A Path Reliable Routing Protocol in Mobile Ad Hoc Networks

In mobile ad hoc networks (MANETs), one of the critical issues consists of the design of routing algorithms that are robust to frequent path disruptions caused by hostspsila mobility. This paper analyzes random walk mobility model, and establishes the relationship between a linkpsilas reliability and current lifetime via a conditional probability model. A path reliable routing algorithm is also developed, in which the proposed analytical model is employed. Simulation results show very good agreement to the analytical model, and indicate the benefits of the proposed routing protocol in terms of increasing path duration and packet delivery ratio, as well as reducing packet end-to-end delay.
