Network coding (NC) makes content distribution more effective and easier in P2P content distribution network and reduces the burden of the original seeder. It generalizes traditional network routing by allowing the intermediate nodes to generate new coded packet by combining the received packets. The randomization introduced by network coding makes all(More)
Wireless Sensor Networks are easily attacked by jammers. Hence it is important to secure these networks from internal nodes that has a chance to become an adversary. In this paper, a novel approach is proposed for detection of node's maliciousness level for securing WSN's from jamming attacks in cluster-based sensor network. The proposed system works to(More)
— Multicasting is the process of sending the information to multiple destinations. This technology is highly efficient for delivering the large scale multimedia content where the end receivers have identical needs and similar set of system components. But in reality, the end users have heterogeneous set of requirements for different service levels as well(More)
