SECURING FSR PROTOCOL AGAINST DATA PACKET DROPPING IN MANET: AN APPROACH TOWARDS MAKING THE ROUTING PROTOCOLS SECURED

Mobile Ad Hoc Network (MANET) is an emerging area of research in the communication network world. As the MANET is infrastructure less, it is having dynamic nature of arbitrary network topology. So it needs set of new networking strategies to be implemented in order to provide efficient end to end communication. These (MANET) networks have immense application in various fields like disaster management, sensor networks, battle field etc.. Many routing protocols have been proposed in MANET among which Fisheye State Routing (FSR) protocol scales well in large network. Security in MANET is a very difficult problem to incorporate without degrading the performance of the protocol. There are various security issues associated with the FSR algorithm among which is the black hole attack which causes data packet dropping by malicious node. Here we have proposed one scheme to minimize the data packet dropping by malicious nodes in the network.
