Interference-aware Routing Metrics Based on the Wireless Mesh Network

In the study of routing metrics in wireless mesh networks,the metrics such as minimum hop counts,ETX,ETT etc.fail to take the interference problems of wireless networks into consideration,and the paths selected based on these metrics generally are not the optimal path.Therefore,those routing protocols based on them will affect the performance of the whole mesh network such as the network delay,packet loss rate,and throughput.The proposition of interference aware metrics improves the performance of wireless mesh network greatly.
