Morning Session - Sunday, Dec. 14, 2014, 9:00 AM - 1:15 PM

1. T1: Basics of Sensor Networks and Security Issues, Dharma P. Agarwal, Univ of Cincinnati


Wireless Sensor Networks (WSNs) have been primarily introduced for defense application using a large number of wireless sensor nodes (SNs) and a Base Station (BS) to collect information from all SNs, making them useful for many civilian applications. A SN typically combines wireless radio transmitter-receiver and limited computation facilities with sensing of some physical phenomenon using different types of transducers. As there are many physical quantities to be monitored, different types of transducers are needed and possible use of sensors in various application areas are discussed first. Various characteristics of WSNs are covered. Specific details of energy consumption in functional units of MICA2 under different operating conditions are summarized. It is clear that more power is consumed in data communication as compared to local computation. With increased use of WSNs in civilian applications, there is a need to learn about how WSNs can be used as sensed area is easily accessible and SNs can be placed wherever desired. Potential use of SNs in indicating the physiological condition of a soldier is also presented. Boundary of a wild forest fire is determined. Analytical model is introduced and obtained curves are compared with simulation results. Secured communication in a WSN is an important aspect ignored by researchers and an innovative technique of distributing keys for shared secret key based communication is described and various characteristics including resiliency are outlined. The need for layered sensing in providing security is also investigated and various alternatives in providing different levels of security are also investigated. Finally, applications of WSNs in unusual areas are also discussed.

2. T2: Emerging Trends in Cloud computing and Role of NFV and SDN for next generation networks, Laxman, B., Freescale


Today Network operators and service providers are facing challenges in hosting different services on to data centers with increasing demands of video streaming, VOIP, Big data processing, social networking and other internet applications. Cloud computing is evolving to host the services on to high volume servers with IT virtualization technologies. Network Function Virtualization (NFV) had emerged as operator’s proposal for offering network services with network functions implemented in software, which can run on Virtual Machines (VMs) with the advent of Server virtualization. There by dynamic networking is evolved through elasticity and agility in launching the services apart from reducing the CAPEX and OPEX. Software defined Networking (SDN) had evolved as Data center (DC) technology to achieve network abstraction with the network services coming up and going down dynamically in the cloud based on the demand. Open flow Infrastructure had come big in a way to separate the control plane functionality from forwarding to compliment NFV, where network intelligence and state are centralized in the form of controller. Key challenges in the cloud with distributed network services are related to Orchestration of services, traffic flow control, security, scalability and performance. This session mainly focuses on advancements and research aspects in cloud computing with respect to networking services (NaaS), Infrastructure (IaaS) and provides more insight on architectural frameworks of Network function virtualization with Software defined networking for addressing the challenges of next generation networks.

2. T4: Information Centric Networks: the Internet of the future,  Anantha Simha, Hemant Kumar Rath, Samar Shailendra, Bighnaraj Panigrahi and Rajan MA, TCS


In recent times, the demands from users and the requirements from the Internet have changed dramatically. Today, huge amount of data is being generated and shared among the users in the form of social networks, online streaming, live TV/videos, online gaming, sensor networks, etc. Accessing such huge amount of data brings up at least two key problems: (i) huge bandwidth requirement in Internet core and access links and (ii) access delay. Both of these problems impact cost & service quality of the Internet access and resource utilization. Today, this is being handled by large content aggregators such as Google, Youtube etc., through large distributed data/cache centres, while at the same time telecom operators all over the world are forced to upgrade the access and core networks to meet this demand. Information/Content Centric Network (ICN/CCN) is an alternate approach to handle this data transfer in the Internet. The principle of ICN says that a communication network should allow a user to focus on the data that is required, while the network itself should be able to support the request with minimal strain on its resources. Since it is not be possible to have a clean slate architecture for the future Internet, the proposed solution should be deployable as an overlay network without bringing any significant changes in the existing infrastructure and should be able to address the twin problems identified above thoroughly. Along with ICN architecture, naming and routing of the ICN data, optimal and scalable content storage/caching, distribution, ensuring security and privacy to the contents are various challenges that need to be solved to build this future Internet. With a lot of data being transferred in wireless networks, the concept of ICN in wireless networks can also revolutionize the future Internet. In the recent times, ICN has gained special attention in the research and business community. IRTF has a dedicated ICN Research Group (ICNRG) for ICN research. ICN has been envisaged as a potential candidate for the future Internet. ICN is going to be an important technology for large content owners as well as the distributors.

4.  R.K. Shyamasundar, FIEEE, FACM, Senior Professor and JC Bose National Fellow, Faculty of Technology & Computer Science, Tata Institute of Fundamental Research, Mumbai 400 005, India
    Title: Towards a Foundation of Security of SCADA
    Time: Dec. 16, Tuesday, 2:15 PM - 3:00 PM
    Chair: Bhabani Sinha (Indian Statistical Institute, India)


Due to technological advances, it has been a common practice for quite some time now to use embedded computers for the monitoring and control of physical processes/plants. These are essentially networked computer-based systems consisting of application-specific control-processing systems, actuators, sensors etc., used for digitally controlling physical systems within a defined geographical location such as power plants, chemical plants etc. Different terminologies like distributed control systems (DCS), cyber-physical systems (CPS), supervisory control and data acquisition systems (SCADA) etc., are used to denote the same. Technology has further made it possible to federate/ integrate heterogeneous (even built by different manufacturers) systems. While such capabilities have provided the needed flexibility and user convenience, it has also created challenges for system designers not only from the correctness point of view but also from the point of view of security and protection of the underlying physical plants. With the arrival of complex malwares, it has become very challenging to secure network and information systems from intruders and protect the systems from attackers. Recently, complex malwares like Stuxnet, Flame etc., have specifically targeted SCADA of public infrastructures like power grids/plants, and thus, bringing to the forefront the challenges in securing and protecting SCADA. The above mentioned malwares are horrendously complex and hence, need a wholesome approach for detection and protection. In these scenarios, apart from the classical IT security, there is a need to look at other plausible new attacks considering the domain of the physical systems and arrive at methods of protection and risk evaluation. In this talk, I shall discuss the challenges various domains in securing SCADA and highlight some of our work referred to as an algorithmic data-intensive approach (also referred to as Bigdata approach) for protecting and securing SCADA from attacks from malware in a wholesome manner.

    Title: Musings on the Future Cloud in India
    Time: Dec 17, Wednesday, 9:00 AM - 9:45 AM
    Chair: Krishna M. Sivalingam (Indian Institute of Technology Madras, India)


Cloud computing is making its presence felt in India. Though, owing to uneven availability of bandwidth and of devices such as smart phones, tablets and laptops the use of cloud computing has yet to penetrate to the mass level. This is likely to change dramatically in the next 5-10 years with rapid proliferation of wireless data networks and of low-cost smart devices. As the cloud becomes mainstream in India, will the cloud serve our needs and aspirations as a sovereign people, or will we become subservient to the cloud?
    In this talk, we speculate on the cloud in India's future based on extrapolation of personal computing hardware trends. There are several possibilities including corporate, public and community clouds. Key to having a cloud that serves India is control and ownership of data. This gives rise to a number of technical challenges. We outline the changes needed in today's cloud to serve India in the decades ahead, changes that will provide many opportunities for researchers and industry.

Invited Talks

1.  Anantha Simha, Principal Research Scientist, CTO Networks Lab, TCS
   Title: Device-to-Device (D2D) Communication and Offloading – A step towards 5G 
   Time: Dec. 15, Monday, 10:45 AM - 11:05 AM
   Chair: Deepak Kataria (IPJunction Inc, USA)


In the last few years the world is witnessing a mobile data tsunami mainly due to increasing number of mobile devices, smartphones, tablets, mobile broadband enabled laptops/palmtops, Internet of Things (IoT), etc. There are more than 5 billion of such wirelessly connected mobile devices in service today. In the future, such human-centric connected devices including surveillance cameras, smart-city, smart-home, smart-grid devices etc., are expected to increase by 10- to 100-fold. This huge transition will present a formidable challenge in the field of wireless communication. With this trend, it is possible to conclude that within the next few years, wireless communication systems will have to support more than 1,000 times today’s traffic volume. This is a worldwide phenomenon and the trends in India follow closely those witnessed elsewhere.

Thus, in order to meet the data rate requirement while maintaining the Average Revenue per User (ARPU), the operators not only need to find-out cost effective solutions, but also look for solutions which are complementary and do not change their existing network completely, thus keeping their CAPEX low. Instead of a “one technology fits all”, complementary technologies should be used to address the data growth requirement. The seamless integration of such complementary technologies with evolved 3G and 4G will bring a new consumer experience and enable introduction of a host of new services and can be called as the evolution towards 5G. Technologies such as WiFi, Small Cells and Device to Device (D2D) have emerged as complimentary solution methods by which the access as well the back-haul capacity can be improved through simultaneous transmission or offloading of the cellular traffic through WiFi, Small Cells, and D2D communications.  We take one such technology, D2D, for further elaboration.

Mobile users in today’s cellular networks (2G/3G/4G) use high data rate services (e.g., video sharing, gaming, social-networking) in which they could potentially be in range for direct communications (between two mobile devices). Due to the fixed infrastructure based communication in a cellular system, many a time, although the mobile users are communicating (sharing files) in close proximity (in a stadium, club, office, homes, etc.), they require to follow the existing cellular transmission procedures, i.e., communication between two mobile devices will be through the Base Station or eNB. This is a resource consuming process, even though the devices are in close proximity. To avoid this, we propose to discuss a technique in which the close proximity devices can communicate with each other directly (Device-to-Device: D2D) without the complete intervention of the eNB. By doing this, re-use of cellular resources (sub-carrier/channel/Resource Blocks) can be made possible resulting in improved spectral efficiency, reduced cost of operation and improved customer experience. D2D can also be useful in enabling multi-hop relays in cellular networks, multi-casting, peer-to-peer communication, video dissemination, machine-to-machine (M2M) communication, cellular offloading, and so on.

Deploying D2D communication in practice requires certain changes such as dynamic power control  at UEs, access to location and channel information of UEs at the eNB, etc., through standardization at 3GPP or TSDSI level in which operators, equipment manufacturers and regulators are to be involved.

Since high cost of operation and low spectral efficiency are the two major factors obstructing the growth of world telecom in general and Indian telecom in particular, we believe that by using D2D communication, major technical and business hurdles of 5G can be  handled. We at TCS, are working closely with cellular operators and equipment manufacturers in this regard, such that a holistic solution can be achieved in future.  This talk will highlight some of the challenges faced in this 5G evolution as well as some techniques to address the same.

2. Anupam Joshi, Oros Family Chair Professor, Director, UMBC Center for Cybersecurity, Visiting Professor, Center of Excellence in Cyber Systems and Information Assurance, IIT Delhi
    Title: Context Aware, Policy based approaches to (Network) Security
    Time: Dec. 15, Monday, 11:05 AM - 11:25 AM
    Chair: Deepak Kataria (IPJunction Inc, USA)


Traditional approaches to securing systems tend to be fixed and mostly non adaptive. The Policy that defines the security posture is in some sense "hardcoded". In this talk, we focus on approaches to securing systems using approaches that have declarative policies that factor in dynamically evolving context. The approach is grounded in W3C standard representation formats for knowledge and formal logic. We show instances of this approach in two different network settings -- mobile devices and intrusion detection.

1. Title: Prediction and Analysis of Cascades on Twitter
    Author: Mona Gupta, IIT Delhi


Social Networks play an important role in spreading information as people can share the information with a large number of users concurrently. The content posted by a user can spread further by retweeting and discussions on the content can be started by replying to the tweet, thus forming large information cascades. A large amount of research has been done in characterizing the information cascades and some work has been done to predict the information cascades. One of the recent work is done by Cheng et al. [1] in predicting the cascades on Facebook. Since Twitter is one of the most influential site where users can share news, opinion, and almost everything, we have chosen Twitter to study the information cascades. We have a dataset of 7.6 million Twitter users from March, 2014 to April, 2014. In this work, we would be presenting a large scale study of the cascades on Twitter by finding retweets and replies of an originating tweet. Most of the prior work on cascades incorporate only retweets and not the replies of a tweet. Replies also play on impotant role in the spread of the information. First of all, we will find the various basic properties of a cascade like size, spread, diameter, path length etc. Dow et al. [2] have studied two large Facebook cascades in detail, but we intend to study the medium sized cascades which are greater in number and see the difference in the network properties of the medium cascades to larger cascades like their growth with time, branching factor, cascade depth, community specificity, role played by root nodes and intermediate nodes. Wang et al. [3] consider user interest, social links, and user influence to recommend the users who should be mentioned to increase the diffusion. But, we also intend to consider network properties along with users social and topical features to predict the growth of the cascade. We also want to identify the variation in the network properties of the two cascades which are started by users who differ largely in the number of their followers count, the two cascades which start at different geographical location, and start at different time. Inspired by the work of Cheng et al. [1], in which they differentiate the cascades based on user initiated and page initiated on Facebook, comparing the cascades based on the properties of the subgraphs, initiated by the individuals and organizations in Twitter will be interesting to study. It will also be interesting to study the properties of two cascades which are competing with each other. By deriving best set of features from the analysis of the cascades, we will apply Machine learning techniques to do prediction task like the growth of a cascade after a certain time period, the effect of a particular user on the growth of the cascade.

2. Title: Quantitative Analysis of Internet Traffic for TCP and Hop-by-Hop Congestion Control
    Author: Sneha Kiran Thombre, IIT Guwahati


Today, Internet faces unprecedented performance challenges in various aspects like heterogeneous environments, mobility and security. The performance of Internet depends on how best TCP works as most of the Internet traffic is carried by TCP. The performance of a particular TCP depends on its congestion control algorithm. However goals of this algorithm are to care for congestion collapse and also to act as resource optimization mechanism in best effort environment. It is important to study how a particular TCP flow characteristic impacts other flows and other protocol at same layer. Hardly any research work is reported in the literature regarding quantitative analysis, clearly showing effects of TCP and UDP on each other, in terms of Quality-of-Service (QoS) parameters. In the former part work we have carried out comprehensive system modeling and exhaustive quantitative analysis of effect of TCP and UDP on each other for predicting QoS parameters like mean delay, network delay, delay jitter and throughput. Modeling network layer traffic includes number of datagrams in aggregate flows, number of bytes in these flows with their respective sizes and fraction of TCP in overall traffic. Initially we focus on the QoS behavior at IP level and the performance of delay sensitive traffic when they are multiplexed with bursty background traffic. The modeling and analysis for mean queuing delay and numerical analysis obtained by transient queuing solution technique for UDP network delay and UDP delay jitter in terms of probability density functions clearly shows that the three parameters mentioned above degrade with the increase in ratio of TCP to UDP as well as with the size of datagrams. When TCP traffic gradually reduces to 0% and UDP traffic increases to 100%, mean delay reduces considerably. This reduction is 48.56% for homogenous case and 78.5% for heterogonous case. For 100% traffic of TCP and 0% of UDP, mean delay in the heterogeneous case is 0.844 s as compared to 0.384 s for the homogenous case. For Instantaneous network delay of a TCP flow when 100% TCP traffic is present is 79 % more to a when TCP flow when only 20% TCP traffic is present, and similarly for TCP throughput is less than 63% when entire background traffic is TCP. TCP degrades UDP network delay and UDP throughput and fellow TCP flows too. We also have compared the theoretical analysis with various ns-2 based simulations. The self similar traffic of TCP due to congestion control mechanism and self similar segment size distribution are the key features which degrade the QoS of overall traffic. To the best of our knowledge, no studies are available TCP and their compatibility with protocol at same layer. So far there is no consensus in research community on the superiority of any specific TCP congestion control mechanism over the other ones. The results obtained provide good insight for the design of better congestion control mechanism so as to improve the QoS demands of modern day dynamic complex traffic. Currently congestion control is seen as a transport layer issue. It is therefore combined with reliability mechanisms, in a TCP-like way. Therefore—like in the Internet—congestion control for unreliable, UDP-like traffic is not possible. A new perspective on this problem should be to realize congestion control in the network layer. After all it makes sense to control congestion problem where it emerges. An exceedingly high network load is a problem closely associated with packet forwarding and media access. Therefore the approach to separate congestion control strictly from reliability measures is what we address in the later part of our work. Reliability can be addressed according to need of application (full, partial and none) by slightly changing UDP or applications can implement according to their requirement. Secondly, Congestion control for non-unicast communication scenarios is also an open research issue. It is proved in literature that link-by-link error recovery performs better than end-to-end approach. On similar grounds a rate based congestion control mechanism in which services rates of routers/switches are adjusted using the feedback provided by neighboring switches. The current buffer occupancy of the immediate downstream switch is the feedback provided to decide the sending rate for the switch in question. We have modeled and analyzed throughput, network delay and stability of this hop-by-hop congestion and flow control mechanism. The probability distributions of traffic arrival and service times of starting node and rest all nodes is modeled, analyzed for QoS parameters like throughput, network delay and stability. We have simulation results using Matlab and Uppaal model checker for comparison with analytical results. Analytical, simulation and Uppaal results clearly indicate that hop-by-hop scheme reacts fast to changes in traffic intensity. The back pressure generated on switches can be handled by designing the buffer sizes of switches. As of now no admission control policy is required. A model checker exhaustively and automatically checks whether the given model meets its specification. Uppaal is an integrated tool environment for modeling, validating and verification of real time systems modeled as networks of timed automata. We implemented Hop-by-hop using Uppaal. It has a number of advantages over traditional approaches that are based on simulation, testing, and deductive reasoning. Model checking is automatic and quite fast. Also, if the design contains an error, model checking will produce a counterexample that can be used to understand error in the model implemented. The results are encouraging and are in progress. So far analytical and model checker outputs agree and indicate that hop-b-hop scheme reacts faster to traffic intensity changes. Advantages of Hop-by-hop are 1) Feedback information is quickly available because of smaller distances between hops. Therefore control mechanism reacts faster resulting in low likelihood of losses. 2) Datagrams can be stored at bottleneck and earlier nodes, so increased capacities are utilized better. 3) We used fixed (210 bytes) of datagrams and aggregated all the traffic streams, then subjected them to feedback-based control so burstiness is minimized to a very large extent. 4) In this mechanism well behaved flows are protected from malicious users. 5) Multicast can be used as Hop-by-hop is implemented at network layer. Finally we intend to propose incremental change in the TCP/IP protocol suite as in fig 1.Congestion control and flow control at network layer using hop-by-hop mechanism and flexible reliability at UDP (transport layer) or at application layer will improve the performance in network delay so delay jitter and throughput. This is improving the Internet performance.

To achieve heterogeneous seamless connectivity with Gigabit wireless speed (~10 GB/s), 1000 times higher mobile data volume per area, and 5 times reduced end to end latency as compared to 4G technology [1] is required for future communication (METIS 2020 and IoT). The researchers and 3GPP (Third Generation Partnership Project) agreed on disruptive changes on wireless communication system at architectural changes, component changes and radical changes and come up with a new generation technology known as Fifth (5 G) Generation Technology. This fifth generation technology has five distinguish key areas where researchers are working to meet the users' expectation. Five key areas are: Device centric architecture, Millimetre wave, Massive MIMO, Smarter devices and Native support for machine to machine communication.

4. Title: Cross Layer QoS Aware Multi Rate Routing Protocol for Ad hoc Network
    Author: Mahadev A. Gawas, BITS-Pilani Goa, Lucy J.Gudino BITS-Pilani Goa, K. R. Anupama, BITS-Pilani Goa


This paper presents an investigation on enhancing the performance on multi-rate Ad hoc networks with congested network. Modern wireless devices, that implement the 802.11b standard, utilize multiple transmission rates in order to accommodate a varied range of channel conditions. Traditional Ad hoc routing protocols use minimum hop paths. These paths operate on long range links that have low effective throughput and low reliability in multi-rate networks. Many rate adaptation algorithms have been proposed to utilize the multi data rate, according to the current channel quality. In this paper, we propose a Cross Layer QoS Aware Multi Rate Routing Protocol for Ad hoc Network (CQMR-AODV) to provide QoS support for real-time multimedia applications in ad hoc networks. Our focus on cross-layer interactions between PHY, MAC and Network layer to utilize these multi-rate support from 802.11b on AODV reactive routing protocol. We propose an effective algorithm that chooses the optimal path with effective data rate and through a less congested network which is compatible with existing 802.11 implementations. CQMR_AODV chooses two metric for route selection, channel link quality of the physical layer and includes MAC layer channel contention information through the number of packets in the interface queue. We have implemented CQMR-AODV in the NS-2 simulator and conducted extensive simulation studies over network diversity. Our analysis shows that the CQMR - AODV protocol significantly increases the network performance in the packet delivery ratio and throughput.
