Improving Route Selection Mechanism Using Trust Factor in AODV Routing Protocol for MaNeT
An ad-hoc network comprises of mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. They are characterized by the use of wireless links, dynamically changing topology, multi-hop connectivity and decentralized routing mechanism and decision-making. The performance of Ad-hoc On Demand Vector (AODV) protocols has been modified by including the source route accumulation feature. As low transmission power of each ad-hoc node limits its communication range, the nodes must assist and trust each other in forwarding packets from one node to another. However, this implied trust relationship can be threatened by malicious nodes that may fabricate, modify or disrupt the orderly exchange of packets.
