Paper Abstract

In this paper we introduce a cross-layer mechanism to enhance the effectiveness of link-state routing protocols by providing a localized estimate of the validity of a given route. Accurate predictions of route staleness result in less packet loss by selecting alternative paths before primary path failures. We present a proof of concept implementation that utilizes shared location and velocity information provided from each node through a common cross-layer substrate. Simulations using random-walk mobility models are presented for the OLSR protocol. The results show that predictive route adaptation can significantly reduce the average packet loss, average delay and jitter.
