Reputation based trust allocation and fault node identification with data recovery in MANET

Mobile ad-hoc network is dynamic in nature with no centralized organizer. The ad-hoc communication depends on the radio range, node mobility as well as intermediate nodes because communication is performed from one device to another with the help of intermediate nodes, that means each mobile node is treated as a route and hence arises the problem of data security in communication, before that proposal number of different trust approach are proposed securing the data from dropping and modification as well as capture attack, in this paper we design reputation base trust allocation system for the node and if any fault occurs in any of the node we will identify the particular node using node packet delivery ratio base analysis, in that technique we will calculate node packet delivery ratio of each node which will participate in the route and we get node packet delivery ratio in less than certain limit that means node is faulty and will search for new route using Location Aided Routing (LAR). Above work behavior is analyzed through Network Simulator-2 test based architecture and also identifies the node trust level and faulty node as well as performance impact of AODV-Trust as well as AODV-LAR-Trust approach.
