Interference-Aware Robust Wireless Mesh Network Design

Interference has been proven to have an effect on the performance in wireless mesh networks (WMN). Using multichannels can improve the performance of WMNs by reducing interference influence. In this paper, we study how to design a robust WMN for a set of mesh nodes, each with Q Networking Interface Cards (NICs) and pre-defined connection requests. Our scheme aims to construct an interference-aware network topology for the nodes, then set up a pair of link-disjoint paths for each request with fault- tolerant capability. We propose two novel schemes to improve the network design. First, we embrace the network interference for providing resource- efficient protections. Second, protection links are shared and reused by multiple connections for protection, which further improves the efficiency of network resource usage. Our simulation results show that our scheme outperformed previous schemes.
