Path reliability metric for proactive MANET routing

One critical issue for routing in Mobile Ad-hoc Networks (MANET) is how to select reliable paths that can last as long as possible, The reliability of a path depends on the number of links and the reliability of each link constituting the path. In this paper we developed efficient routing metric prediction methods by predicting link stability using a probabilistic computation based on the normal-like distributions of the link lifetimes in typical MANET mobility scenarios, integrating it to proactive MANET routing OLSR, named Path Reliability OLSR (PR-OLSR). We show by simulation that PR-OLSR is more adaptive to the network dynamics and therefore is able to improve performance significantly on packet delivery ratio and prolonged network energy lifetime. © 2016 IEEE.
