Impact of Finding Selfish Nodes in Manet

The nodes that operate in the self-organized functions of Mobile Ad hoc Networks (MANETs) participate in the network but increase the energy and resources consumption. As some nodes are non-cooperative with others in the network, it is necessary that those nodes have to be removed. Active researches are conducted to deal with those selfish nodes that are non-cooperative. Methods/ Statistics: Our paper analyzes by comparing the 2ACK method simulated using hash chain one-way scheme with digital signature and DSR methods. Findings: The simulation analysis suggest that a considerable percentage of packets delivered of 2ACK method is greater when compared with Digital signature or any other DSR methods but has the capability in finding a considerable number of selfish nodes present in the network. Applications/ Improvements: the 2ACK scheme can be used to control the network overhead using the authentication schemes and can be enhanced to monitor the video traffic can be monitored.
