Abstract:This paper investigated the effect of heterogeneous interface for the capacity of distributed channel-assignment mesh network, presented a new ILP model of joint radio and channel assignment, which considered radio-links as the object of channel-assignment, and proposed a new distributed greedy algorithm. It was an adaptive distributed algorithm, which could get the maximal sum of radio-links throughput with the weight of queue length, based on 2-hop interference model and the load of the network. It found this algorithm has the same time-complex order as Dist. Greedy algorithm with homogeneous interfaces. The simulation result shows that this algorithm can improve the performance of the network efficiently. ......
