Secure Multipath Routing Scheme for Mobile Ad Hoc Network

Mobile ad hoc networks (MANETs) are collections of autonomous mobile nodes with links that are made or broken in an arbitrary way. Due to frequent node and link failures, multipath MANET is preferred than single-path MANET in many applications. Multipath routing schemes are used for achieving various goals such as robustness, reliability, and load balancing. However, before they can be successfully deployed several security threats must be addressed. Due to lack of fixed infrastructure, security in ad-hoc routing is challenging task, especially in multipath MANET. In this paper, we propose a robust multipath routing scheme for MANET and also security mechanism for such a routing scheme. We discuss security analysis for our scheme. And we conduct simulation to evaluate the cost of the proposed secure multipath routing scheme and present some preliminary results.
