Investigations on detection of misbehaving nodes using routing statistics and priority based resource sharing in manet

Abstract

The explosive reputation of mobile devices and the mobile newlinetechnology leads to extreme recognition of the Mobile Ad Hoc Network newline(MANET). MANET is a collection of wireless battery-operated and newlinedecentralized nodes connected together in a dynamically changing newlinecommunication network. It functions as self-configured and self-maintained newlinemanner and established without using any proper fixed infrastructure. newlineMANET nodes are moving randomly as the network topologies changes quite newlineoften and each node needs to play a router role to relay the traffic to other newlinespecified node in the network. The cooperation among these nodes is highly newlineconsiderable for medium access and routing. MANET established in such a newlineway that all the mobile nodes are treated as equal. Multi-hop communication newlinebecomes unavoidable as the network is too big and direct communication may newlinenot be possible between every pair of nodes. newlineThe nodes within the transmission range can communicate directly. newlineHowever, the nodes outside the transmission range need the help of other newlinenodes to relay messages. Thus, a multi-hop communication is much required newlinein which several intermediate nodes need to work together to forwards the newlinepackets to the destination node. In routing, the nodes need to work together to newlineidentify a set of routes and take part in packet forwarding to deliver the newlinepackets to the desired destinations, which are outside of their transmission newlinerange. If the nodes are not cooperating, operational routes may not be found newlineand end-to-end packet delivery may not be possible. Every node has to think newlineabout its limited energy or other resources, thus every node tends to newlinecontribute as modest as possible of its own resources newline
