Despite the many routing protocols to choose from in the existing wireless network literature, routing has remained a challenging problem in the actual deployment of wireless mesh and ad hoc networks. To address some of the issues in-volved with routing in wireless mesh networks, in this paper we attempt to make routing more sensitive to the dynamics of the network such as interference, traffic load and conges-tion. We introduce a link/load-sensitive metric using links' idle time and average Signal to Interference Noise Ratio (SINRJ, as perceived by receiving nodes into link/path se-lection. We use this quantity as a secondary link metric to prevent instability that might happen due to frequent SINR variations. We therefore attempt to introduce better load balancing critical to mesh networks as the nodes closer to the base stations tend to be the natural bottlenecks of the network. We perform a simulation study to assess the per-formance enhancement due to this technique under differ-ent load conditions. We use ETX as primary link metric and observe throughput enhancement when a secondary SINR-based metric is incorporated in the link metric.
