Abstract: Considering that both of intra-flow and inter-flow interference have a great impact on path performance, based on wireless mesh networks, this paper proposes a routing metric FIA which is comprehensively aware of flow interference. The metric takes channel as unit and captures the transmission data size of all interfered link of each hop in path to measure the inter-flow interference. Furthermore, the metric measures the usage of each channel by getting the maximum of the interfered transmission data size to consider both of intra-flow and inter-flow interference at overall. This paper sums up the measurement result and the expected transmission time of the path with a weight for balanced to consider both of the transmission delay and flow interference. Simulation results show that the FIA performs better in terms of throughput and packet loss rate.
