Enhanced node cooperation technique for outwitting selfish nodes in an ad hoc network

摘要: In an ad hoc network, selfish nodes do not cooperate in packet forwarding of other to maximise their own welfare. Such will have a negative effect on the performance network. this study, enhanced node cooperation technique (ENCT) is proposed which hybrid reputation-based mechanism and incentive-based mechanism. It evaluates relaying nodes’ behaviour, calculates its reputation outwitting by utilising receipts submitted each path centralised authority rather than using promiscuous mode. A mathematical analysis provided demonstrates that expected gain for particular maximum if it adopts cooperative behaviour. To motivate cooperation, variable incentives are proportionate current Simulation results demonstrate modification incentive with varying number nodes, traffic connections, topology static dynamic behaviour nodes. The result shows ENCT robust, fair efficient technique.
