Proactive Resilience to Dropping Nodes in Mobile Ad Hoc Networks

Abstract. Proactive routing protocols for mobile ad hoc networks currently offer few mechanisms to detect and/or counter malevolent nodes. Stability and performance of most, if not all, emerging standard proactive protocols rely on cooperation between nodes. While cryptographic methods may be a solution to secure control messages, nodes not willing to cooperate may still decide not to forward data packets. In this paper, a method to enable resilience to such malevolent nodes is presented. It is non-intrusive with respect to the packet forwarding mechanisms (e.g. TCP/IP kernel stack) and particularly well suited for integration with proactive routing protocols. Key words: proactive routing, ad hoc networks, malicious nodes, resilience.
