Metric Anticipation in Mobile Ad-Hoc Networks
Abstract
In this paper, we propose a new method for metric calculations. It aims to improve mobility management in wireless networks. The idea consists in anticipating metric values in order to compensate the delay generated by the measure of the link quality and the routing protocols. As an example, we consider the popular ETX (Expected Transmission Count) metric. We focus on ad-hoc networks, even if our approach could be used in other contexts. We show by simulations that our approach, when well parametrized, allows a Packet Delivery Ratio (PDR) close to 100% when nodes are moving.
