摘要：A MANET is referred as an infrastructure less network because the mobile nodes in the network dynamically locate paths among themselves to transfer packets provisionally. Security is core concern in routing protocol of MANET and affects the performance. Here, a innovative request forwarding mechanism is proposed in which source node generates route request packet and broadcast packet to other neighbor nodes to locate destination by implementing black hole attack. Enhanced DSR Routing is proposed & implemented by using selfish nodes in network, and it is found from results that enhanced DSR routing protocol is better than existing DSR protocol on performance measures such as throughput, routing overhead, end to end delay and packet delivery ratio. As mobility increases, there is significant decrease in communication overhead that is almost about 60% than DSR protocol which is one of the main beneficial point of our proposed protocol and also as speed increases end to end delay is also decreases almost 45% than DSR, It has been found that on dense network certain numbers of selfish nodes are supportive to reducing communication overhead.
