Abstract :

As a result of the changes in people’s life and the conveniences of the wireless communications, the wireless networks showed
increasing growth during the last few years. Therefore many kind of mobile wireless devices are supported; i.e. the smart
phone, the tablet PC, and the notebook. The MANET, different to the wireless networks with infrastructure, does not need any
access point (AP) device. MANET relies on the cooperation of all the participating nodes. In MANET, the source nodes can
relay packets to the destination node by other nodes. If the intermediate nodes have misbehaviors in the communication path,
the throughput of MANET will be degraded. These misbehaviors are due to the selfish nodes. How to detect these selfish nodes
in MANETs is very important. We will adapt AODV (Ad hoc On-Demand Distance Vector) routing protocol in MANET in
this paper. Also we use ns-2 simulator to observe and verify the proposed algorithm in this paper. Finally we analyze the results
obtained from ns-2 simulator.
