Packet Dropping Alleviation In Mobile Adhoc Networks By Power Saving AODV

In a mobile ad hoc network every node acts as a router for its neighbor. The existing routing protocols assume that the all the nodes will fully participate in the transmission of packets. Though usually a waiting time is allotted for each participating node to send its data, some nodes, however, behave maliciously, by dropping the packets. This paper aims at developing an algorithm to detect misbehaving nodes and prevent such misbehavior by incorporating promiscuous properties in AODV. The new routing algorithm extensions presented in this paper make it possible to detect and isolate misbehaving nodes with energy saving mechanism, thus making it unattractive to deny cooperation. In the presented scheme, trust relationships and routing decisions are made based on experienced, observed, or reported routing and forwarding behavior of other nodes.
