Analytical Impact of Reputation based scheme on DSR protocol for Evaluation of MANETs
MOBILE ad hoc networks (MANETs) are collections of mobile nodes, dynamically forming a temporary network without pre-existing network infrastructure or centralized administration. The dynamic nature of mobile ad-hoc networks make traditional routing protocols unsuitable for MANETs. Their Security requirements and also unlike the traditional networks and are more complicated and stringent. Various routing protocols designed for ad-hoc networks fulfilling a unique set of requirements are ADODV, DSDV, TORA, TBRPF and DSR. The Dynamic Source Routing is a simple and robust protocol designed for use in multi-hop Some nodes though, in order to save resources, may exhibit a selfish behaviour and not co-operate, thus damaging the efficiency of entire network. This paper proposes a set of minor extensions to the DSR protocol proposed by the IETF MANET working group, by implementing the reputation based scheme on it, that enable to increase the performance of the network. The proposed mechanism allows a node to autonomously evaluate the “reputation” of its neighbours based on the completion of the requested services. Simulations will show the increase in throughput and packet delivery ratio, decrease in data drop and routing overhead on the basis of some network metrics used.
