Peer-to-peer network is one in which each node in the network can act as a client or server for the other nodes in the network. It allows shared access to various resources such as files, peripherals, and sensors without the need for a central server. Content distribution in the P2P network from server is done by multicasting. Multicasting is the process of(More)
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)
This paper focuses on cognitive radio network (CRN), in which a group of nodes communicate over a shared wireless medium with a limited bandwidth. Here frequency channel for transmission of primary radio network (PRN) which is the legacy network will be shared to the secondary users (SU). Whenever resources are shared there exist a strong need of scheduling(More)
Jammers may easily attack the Wireless Sensor Networks. Hence it is essential for securing these networks from malicious nodes. In this paper, a novel system is proposed to detect the node’s maliciousness level for securing WSN’s from jamming attacks in cluster-based sensor network. The proposed System that detect the maliciousness level using Packet(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 as(More)
