A Robust Technique for verifying the neighbor positions in MANET

Mobile ad-hoc network is a collection of independent mobile nodes that can communicate to each other via radio waves�. After nodes are deployed, they do not have knowledge about the neighbors so, they need to discover their neighbors in order to communicate with them. Knowledge of the neighbor nodes is essential for almost all routing protocols, medium-access control protocols and other topology control algorithms. Now, neighbor node may be trustable node or adversarial node so verification of node is require. For neighbor position verification NPV protocol is used. NPV protocol deals with verifying the neighbor node location. Nowadays, location awareness has become very important in MANET because wide range of protocol and application require knowledge of the position of participating nodes. So it is require improving NPV protocol. Examples of services that build on the availability of neighbor position information are Geographic routing in spontaneous networks, data gathering in sensor networks, movement coordination among robotics nodes, location specific services for handheld devices. Existing NPV protocol has some limitation like Lower Performance and False Positive Rate and False Negative Rate are high. So the objective of our proposed system is improve the FPR and FNR means minimize the FPR and FNR.
