Neighbor discovery is an important part of many protocols for wireless ad hoc networks, including localization and routing. When neighbor discovery fails, communications and protocols performance decline. In networks affected by relay attacks, also known as wormholes, the failure may be more restrained. The wormholes deny or degrade communications. In this paper, the authors present Mobile Secure Neighbor Discovery (MSND), which offers a measure of protection against wormholes by allowing participating mobile nodes to securely determine their neighbors. MSND leverages concepts of graph rigidity for wormhole detection.
