A Cross-layer Predictive Routing Protocol for Mobile Ad hoc Networks
نویسندگان
چکیده
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.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
