Collaborative Scheme to Detect Stealth Nodes in Mobile Adhoc Networks

Free registration required

Executive Summary

Limited number of nodes are static in Mobile Adhoc Networks. Hence, achieving synchronization between neighboring nodes in such a dynamic environment is complicated considering issues like signal disruptions, transmission power variations, loss of communication. Earlier, a simple protocol that uses a continuous neighbor discovery algorithm through neighbor collaboration was deployed. Besides its ability to address the above issues it can detect hidden nodes that are detrimental to quality and security. Precise knowledge of node localization is important for robust communications in MANETs.
