We present a multiple-metric approach in order to improve routing in wireless mesh networks (WMNs). It is based on the proactive optimized link state routing (OLSR) protocol to deal with applications with high quality of service (QoS) demands. Since routing with multiple metrics is an NP-complete problem, we use the analytic hierarchy process (AHP) and pruning techniques to perform such routing. The proposal, dubbed here OLSR-MM (multiple-metric), offers the best available routes based on the considered metrics and is evaluated on Network Simulator 2.31.
