AN ALGORITHM FOR A SECURE PATH IN MOBILE AD HOC NETWORK

Mobile Ad hoc Networks (MANETs) consists of a group of wireless mobile nodes which exchange data dynamically among themselves without based on a fixed base station or a wired backbone network. The ad-hoc network provide lack of secure boundaries. The ad-hoc network may also provide some intrusion.Ad hoc is used to describe solutions that are developed on-the-fly for a specific purpose. Computing nodes (usually wireless) in an ad hoc network act as routers to deliver messages between nodes that are within their wireless communication range. Intrusion is one of the common problems in all networks in case of ad hoc network we face the same problem. When we have a dense sensor network with number of nodes and there is some important data is transferred over the network, there is the requirement of security. But in case of “Man in Middle� it is never easy to say a network is intruder safe. Even when the Intruder knows about the routing algorithms or the algorithm implementation it is quite difficult to handle the problem. We are providing the approach to transfer data from some path other than that common path.
