AN EFFICIENT SCHEME AGAINST VARIOUS ATTACKS IN AD HOC NETWORKS

摘要

Its lack of infrastructure and centralized administration makes security be an important and, in many cases, a critical concern in the research of wireless ad hoc networks. The routes between any two nodes in an ad hoc network are apt to be attacked by various attacks, including those formed by two colluding malicious nodes. Taking advantage of node-disjoint paths between any two nodes, we propose a novel mechanism to provide protection against various attacks, especially the colluding attacks. Our simulation results show that the performance of our scheme on DSR and multi-path routing algorithm is satisfactory.
