Mitigating the misbehavior of nodes at MAC layer in wireless ad hoc network

Abstract

In wireless ad hoc networks, misbehavior of nodes in computation of backoff value is one of the problems that affects the performance at MAC layer. To overcome this problem, this paper proposes a solution in which Contention Window subrange is specified by the receiver to the sender through CTS/ ACK packet. The advantage of sending the Contention Window subrange is, it is easier to detect the misbehaving nodes. From the simulation results, it can be inferred that the proposed solution reduces the misbehavior of the nodes.
