jit.6.3.13780 Improved Performance of DSR Protocol in Node Failure in MANET Using Netsim Gurpreet Singh Rajat Khurana Journal on Information Technology 2277-5250 6 3 20 24 10.26634/jit.6.3.13780 MANET, DSR, NetSim In this paper, a study has been done on improved performance of reactive ad-hoc routing protocol, i.e Dynamic Source routing protocol in context of increasing number of failure mobile nodes in the network. And simulations are evaluated using Network Simulation (NetSim). Mobile Ad Hoc Network consists of mobile sites that are not having any predefined structure. Because of varying infrastructure these nodes are attacked and may get failure also. In present study, reactive routing protocol, i.e. Distance Vector Routing (DSR) is evaluated on the basis of throughput, packets transmitted, packets errored, and packets collided by increasing number of failed nodes in the network.
