Analysis and prevention of wormhole attack using trust and reputation management scheme in MANET

MANETs operates without fixed framework and all nodes in network perform like a router in sequence to forward information next receiver. Since the pivotal point rein lack, MANETs are additionally pregnable routing attacks as against various grids. Routing is one of the most serious attacks of wormhole attacks that are easier to be implemented nevertheless harder detection. Generally, it operates in two phases; in the first phase, wormhole channel nodes tend to draw more and more traffic route, and by other phase, they loss the grid by altering or dropping the grid traffic. In MANETs, numerous writers have implemented diverse results to prevent attacks. In this paper, we proposed a trust and reputation management scheme for find out the trusted location in MANET environment.
