Collaborative Discovery and Verification of Neighbour position in MANET

Abstract

MANET is an self configuring and infrastructure less based network. A growing number of ad hoc networking protocols and location-aware services require that mobile nodes learn the position of their neighbors. However, such a process can be easily abused or disrupted by adversarial nodes. The fully distributed cooperative NPV solution is robust against independent and colluding adversaries, and can be impaired only by an overwhelming presence of adversaries. In the existing approach, nodes are correct if they comply with the NPV protocol and adversarial if they deviate from it. Results thwart more than 99 percent of the attacks under the best possible conditions for the adversaries, with minimal false positive rates. But there is no secure message transformation. In the proposed approach secure message transformation takes place, so the trusted node informs all the correct nodes about the adversarial node, and the node will be removed from network operations cooperatively and the operational load of each correct node is reduced.
