摘要：In an open MANET, different mobile nodes with different goals share their resources in order to ensure global connectivity. However, some resources are consumed quickly as the nodes participate in the network functions. For instance, battery power is considered to be most important in a mobile environment. An individual mobile node may attempt to benefit from other nodes, but refuse to share its own resources. Such nodes are called selfish or misbehaving nodes and their behaviour is termed selfishness or misbehaviour [1]. One of the major sources of energy consumption in the mobile nodes of MANETs is wireless transmission [2]. A selfish node may refuse to forward data packets for other nodes in order to conserve its own energy. Selfish nodes (SN) use the network but do not cooperate, saving battery life for their own communications: they do not intend to directly damage other nodes. This paper proposes Selfish Avoidance Routing Protocol(SARP) for mobile ad hoc network, which takes into account the various factors like the residual battery capacity of a node, power consumption in transmitting packet and the drain rate to increase the battery life of the nodes to overcome the presence of selfish nodes.
