MIP: A New Routing Metric for Wireless Mesh Networks

A new simple and effective routing metric called MIP (Metric of Interference and Propagation Delay) for multi-channel multi-radio wireless mesh networks (WMNs) has been proposed. The new metric combines loss rate, channel capacity, inter-flow interference and intra-flow interference together to find effective routing paths for source-destination pairs in WMNs. MIP is different from any existing routing metrics for wireless networks. It redefine Interference Ratio and tries to obtain balance between channel diversity and path length. Large numbers of experimental rounds prove that the new metric improves the performance of WMN a lot than existing algorithms.
