Abstract: No effective approximate methods about QoS route question are proposed，some heuristic algorithms generally are used，like genetic algorithm，simulated annealing algorithm，ant colony algorithm and so on.In this paper we firstly introduce QoS，its parameters and the definition that restrains the QoS route，then make a comparison between the Ad-hoc net and the wireless mesh networks，and according to present situation of Ad-hoc network research，analyse feasibility for ant colony algorithm in wireless mesh networks with QoS.

Key words: multi-constrained QoS, wireless mesh networks, ant colony algorithm
