The key confront in Mobile Ad hoc NETwork (MANET) is its dynamic nature, which itself carries security measures. The Mobile Ad hoc Network is multi-hop in nature where nodes are required to perform communication activity for end to end connectivity which is being used for transferring data packets and thereby spending its resources. A selfish node is one that tries to consume the network resources for its own benefit but is unwilling to spend its own resource for others. If such selfish behavior continues among nodes in network, it may be harmful for network by creating disorder. In this paper, Proposed ES-DSR (Enhanced Selfish DSR) is implemented on NS-2 and results shown significant improvement over original DSR in terms of performance evaluation of network.
