An approach to suppress selfish behavior of a node in MANET by hiding destination identity in routing path

Abstract

In wireless ad hoc networks, each node cooperates with each other to forward the data packet. However, some of the nodes behave selfishly and disincline to share their resources with other nodes. This selfish behavior of nodes at network layer degrades the performance of the network significantly. In this paper, a novel approach is proposed, to suppress the selfish behavior of nodes and encourage each node to forward the data to its next node in the routing path. This work is inspired from the One More Hop (OMH) approach, in which each node in the network is believed to be rational i.e. each node want to send and receive its own packet in the network. In this paper, a source node always finds a longer path for destination. Here, the term longer path consists of actual routing path from source to destination and an extra path from destination to other disjoint nodes. This extra path may be either fake or real depending on availability of extra path at destination. © 2011 Springer-Verlag.
