In this study, routing metric design for multi‐gateway (MG) wireless mesh networks (WMNs) where partially overlapped channels (POCs) are used for data transmissions is investigated. POCs, multiple gateways and routing are effective solutions for capacity improvement in WMNs. Previous research designs routing metrics for WMNs where only orthogonal channels (OCs) are used. As interference estimation of POCs is quite different from that of OCs, these routing metrics are not suitable for POCs WMNs. In this paper, a light‐weight uniform description of interference‐based routing metric is proposed, and to the best of our knowledge, this is the first routing metric specifically designed for MG POCs WMNs. Equivalent bandwidth is defined to capture the unique characteristics of POCs WMNs accurately, and gateways are also paid close attention to. This metric combines the optimal gateway selection together with the optimum path selection, and simulation results show that it can help select low‐interference and light‐load paths to light‐load gateway for data flows.
