Administrator and Trust Based Secure Routing in MANET

The advent of mobile ad hoc (MANET) network had spurred in a new era of communication where users (nodes) communicate with each other via a self configuring infrastructure less network of mobile devices connected by wireless links. Nodes can participate both as a host as well as a router willing to forward packets for other nodes. So here arises the need of a routing protocol. Now the dynamic topology of the network owing to the node mobility becomes the most challenging part of a routing protocol as it demands a protocol which quickly adapts to topology changes with minimizing control traffic such as periodic update message because of limited resource like storage capacity, battery power and bandwidth. In this paper, we have proposed a new routing scheme, Administrator and Trust Based Secure Routing in MANET (ATSR) which provides routing by making an important use of a parameter, trust, an integer value, helping in the selection of administrator inside the network for routing. The message confidentiality and integrity has also being implemented. The simulation result shows the efficiency, lustiness and trustworthiness of our proposed routing scheme.
