A secured MANET using position-based opportunistic routing and SEMI MARKOV process

摘要

Inthe mobile ad hoc network (MANET), the nodes are moving very frequently and they do nothave any fixed infrastructure. For reliable data delivery inMANET,we have analyzed the efficiencyof data delivery using Position-based Opportunistic routing method and greedy forwarding technique,which is based on geographic routing method. Initially, theMANETis divided into a numberof provinces to identify the location of the receiver, and then Geographic routing is applied on thenetwork for transmission of data. Based on the performance and throughput, the best forwardernode will be identified. Semi Markov process is used to develop the node behaviormodel for networksurvivability. In this work, reliable data delivery is obtained for the MANET by estimatingthe present performance of the network through isolating the forwarder node in Semi Markovprocess.
