A MANET (Mobile Ad-hoc Network) is a self-configuring system of mobile nodes connected by wireless links. MANETs are self-configuring and decentralized without having a fix infrastructure. In such a network each node acts as an end system as well as a relay node (or router). Most of the routing algorithms designed for MANET such as AODV and DSR are based on the assumption that every node forwards every packet. But in practice some of the nodes may act as the selfish nodes. These nodes use the network and its services but they do not cooperate with other nodes. Such selfish nodes do not consume any energy such as CPU power, battery and also bandwidth for retransmitting the data of other nodes and they reserve them only for themselves. The original AODV and DSR routing algorithms can be modified to detect such selfish nodes. This paper discusses two techniques namely Reputation based technique and Credit based technique used to detect selfish nodes in MANET. This paper concentrate on two algorithms that are based on reputation based technique and one algorithm based on credit based technique. All the three techniques have been compared finally.
