Multi-path routing protocol using cross-layer congestion-awareness in wireless mesh network
Hung Quoc Vo, Young Yig Yoon, Choong Seon Hong · 2008
Recently, the WMNs (Wireless Mesh Network) have increased their popularity and kept the interest of the most important research groups all over the world due to their self-configuring, self-healing capabilities, as well as their low equipment and deployment cost. Most of research work carried out in WMN is prone to be simple, practical to build up confidence in commercial implementation of these networks. In this paper, we present a multi-path routing protocol using Hop-Count metric that can be aware of congestion by collecting information from MAC layer. The primary advantage of our paper is to provide a simple and stable multi-path routing algorithm that can provide better than best-effort to real-time applications in wireless environment but need much less overhead compared to QoS-aware routing with two kinds of metrics: bandwidth and WCETT (Weighted Cumulative Expected Transmission Time).
