Wireless mesh network is a kind of multi-hop and distributed wireless network which can provide many sorts of wide-band multimedia services.At the present,the research of wireless network in routing technology is still at the starting stage. This paper firstly introduces several famous routing protocols in wireless mesh network and analyses the deficiency of those routing protocols,based on which,this paper then puts forward a new routing algorithm which can remarkably improve the performance of the network because of its comprehensive consideration on three factors: link quality,the balancing of load on each node and channel interference.The analysis and simulation results indicate that the new routing algorithm can evidently improve network throughputs and reduce transmission delay and it has nice interference immunity.
