For any node in a Mobile Ad hoc Network conservation of battery power and bandwidth are the priority. Hence, they try to reduce the overload they would otherwise incur when they forward packets. This selfish behavior of a node affects the throughput of the network. The nodes may also choose a back off value of shorter duration. These problems are handled effectively by the methodology proposed in this paper. A conscious effort has been made keeping the constraints of the MANETs in mind. An algorithmic approach for misbehaving node detection and isolation in ad hoc networks by modifying the protocol being used in the lower layers which consequently improves performance of the network had been proposed.
