PAPER ONE
Secure Video Transmission Against Black Hole Attack in MANETs
M. Umaparvathi, Anna University of Technology, India
Dharmishtan K. Varughese, Karpagam College of Engineering, India
Mobile Adhoc Networks (MANETs) are open to a wide range of attacks due to their unique characteristics like dynamic topology, shared medium, absence of infrastructure, and resource constraints. Data packets sent by a source node may reach destination through a number of intermediate nodes. In the absence of security mechanism, it is easy for an intermediate node to intercept or modify the messages, thus attacking the normal operation of MANET. One such attack is Black hole attack, in which, a malicious node called Black hole node attracts all the traffic of the network towards itself, and discards all the packets without forwarding them to the intended recipients. This paper evaluates the performance of Adhoc on-demand Distance Vector (AODV) and its multi-path variant Adhoc On-demand Multi-path Distance Vector (AOMDV) routing protocols under black hole attack. Non-cryptographic solutions Secure Blackhole AODV (SBAODV) and Secure Blackhole AOMDV (SBAOMDV) have been proposed to mitigate the effect of black hole attack. Through NS-2 simulations, the performance of the proposed protocols with video streaming is analyzed. The results show that the proposed solutions provide better performance than the conventional AODV and AOMDV.

PAPER TWO
Enhancing Clustering in Wireless Sensor Networks with Energy Heterogeneity
Femi A. Aderohunmu, University of Otago, New Zealand

Martin K. Purvis, University of Otago, New Zealand
While wireless sensor networks (WSN) are increasingly equipped to handle more complex functions, in-network processing still requires the battery-powered sensors to judiciously use their constrained energy so as to prolong the elective network life time. There are a few protocols using sensor clusters to coordinate the energy consumption in a WSN, but how to deal with energy heterogeneity remains a research question. The authors propose a modified clustering algorithm with a three-tier energy setting, where energy consumption among sensor nodes is adaptive to their energy levels. A theoretical analysis shows that the proposed modifications result in an extended network stability period. Simulation has been conducted to evaluate the new clustering algorithm against some existing algorithms under different energy heterogeneity settings, and favourable results are obtained especially when the energy levels are significantly imbalanced.

PAPER THREE
New Strategies and Extensions in Kruskal's Algorithm in Multicast Routing

Multimedia applications are expected to guarantee end-to-end quality of service (QoS) and are characterized by stringent constraints on delay, delay-jitter, bandwidth, cost, and so forth. The authors observe that Kruskal's algorithm is limited to minimal (maximal) spanning unconstrained tree. As such, the authors extend Kruskal's algorithm to incorporate the delay bound constraint. Consequently, a novel algorithm is proposed, called EKRUS (Extended Kruskal), for constructing multicast trees. The EKRUS' distinguishing features consists of a better management of Kruskal's priority queues, and in the provision of edge priority aggregation. Preliminary results show that the proposed EKRUS algorithm performs as well as the best-known algorithms (such as the DDMC, DMCTc algorithms) while exhibiting reduced complexity. The authors conducted an intensive analysis and evaluations of different strategies of assigning edges into the classes of the queue as well as edge selection. As a result, the EKRUS algorithm was further extended with different edge assignment and selection strategies. Through extensive simulations, the authors have evaluated various versions of the EKRUS and analyzed their performance under different load conditions.

PAPER FOUR
Emerging Areas of Research in Business Data Communications
Debashis Saha, Indian Institute of Management Calcutta, India
Varadharajan Sridhar, Sasken Communication Technologies, India
Much like the financial crisis that precipitated a new world order, a quiet revolution of some sorts is happening in the telecom industry worldwide. The bankruptcy of stalwarts such as Nortel and the impregnation of Google and Apple into the mobile phone space at an amazing alacrity are changing the world order once dominated by the likes of biggies such as AT&T. What are these changes and what can we expect in the future? We explore in this article, the emerging technologies, market evolution, business models and regulatory interventions and indicate possible research directions in the area of data communications and networking in the coming days.
