Rose Ann Cyril, Saritha S . A Survey on Evaluation Schemes for Routing Misbehaviors in Manet. International Journal of Computer Applications. 78, 11 ( September 2013), 7-11. DOI=10.5120/13531-0677
Mobile ad hoc network has emerged as a trending topic of research in recent years owing to the highlighted pervasive computing culture. MANETs are decentralized, and therefore all network activities are carried out by nodes themselves. Transmissions are not controlled by any central authority as like base stations in the case of cellular networks. Each node is both an end-system as well as a relay node (router) to forward packets for other nodes. This requires that every node in the network contribute full cooperation as to cater to the routing needs of adhoc network. The route creation and maintenance tasks in Manet are autonomous operation. The flexibility of wireless transmission is however affected by its limitations as well like limited range, bandwidth, energy constraints etc. To cope up with these limitations, many a time's mobile nodes may decide either not to cooperate or partially cooperate for the benefit of their own. This strategic dimension of mobile nodes to conserve energy may be detrimental to the health of efficient Manet systems. Selfishness substantially reduces the performance of network at the routing layer. The selfishness may also cause data loss making the scenario more badly. It is hence the need of the hour to discover the selfish nodes and device new schemes wherein data accessibility is never affected on varying environments.
