A Secure Prioritized Trust Based Multi-path Routing Protocol for Ad Hoc Networks

Security in infrastructure-less networks like MANETs (Mobile Ad Hoc Networks) has proven to be a challenging task. Multipath routing protocols were initially proposed in order to design robust and secure networks. These protocols improve network performance in terms of delay, throughput, reliability and life time. It is hard to find a single protocol that can improve all these performance parameters. In this paper we propose a secure prioritized trust based multi path routing protocol. It ensures reliable communication with low overhead and minimum delay. This is realized by discovering and selecting reliable path based on the trust information. We take the advantage of multiple paths to increase reliability and robustness of data through context aware routing. Results show the effectiveness of our protocol.
