Abstract
Medium access control MAC protocols such as IEEE 80211 are used in wireless networks for sharing of the wireless medium The random nature of the protocol operation together with the inherent difficulty of monitoring in the open poses significant challenges All nodes are expected to comply with the protocol rules But some nodes in order to gain greater benefits misbehave by not complying with the rules One such selfish misbehavior is waiting for smaller backoff intervals when compared to the other nodes in the same subnet Such selfish misbehavior is being tackled in this paper A diagnosis scheme and a penalty scheme are being proposed for overcoming such selfishmisbehavior at MAC layer of mobile ad hoc networks which could be extended to other types of networks also
