This paper presents a new metric for routing in wireless mesh networks (WMNs). The proposed metric does not only consider the quality of wireless links to choose a high throughput path between a pair of nodes, but it also includes the resulting interference introduced by using such links. The philosophy behind this metric is to choose a good path for an arriving connection, not necessarily the best in terms of throughput, but that alleviates the resulting interference in order to preserve good paths for the subsequent arriving connections. In doing so, we find that our metric significantly outperforms previously proposed routing metrics when multiple concurrent flows are considered in the network. The total network throughput is indeed increased.
