Security-aware Localized Topology Control Algorithm for Mobile Ad-hoc Networks

Abstract

Abstract In this paper, we extend the topology control schemes by making security the primary concern. For this purpose, we propose a security-aware localized topology control algorithm that can maximally avoid making malicious nodes into intermediate nodes. In order to marginalize malicious nodes, we introduce a new metric for characterizing the security status of each link in the network. Each node independently builds a local spanning tree for finding a reduced neighbor set. In the meantime, we maximally avoid using insecurity links in their neighborhood for the local spanning tree construction. Simulation results show that our algorithm significantly improves the security of a network.
