摘要 在多射频多信道无线Mesh网中,是无线宽带接入的重要候选技术之一.为了满足无线宽带接入的容量要求,Mesh路由器节点常需要配置多个无线接口并使用多个正交信道.已有的信道分配方法虽能减少干扰和碰撞,但不能完全避免.本文提出一种域内中心式调度的接口分域信道分配(ICCA)方案,旨在完全避免干扰与碰撞以提高网络吞吐量,尤其能够降低传输时延,特别适合实时业务传输. Wireless mesh network（WMN） is one of the important candidates for wireless broadband access services.In order to meet the requirements of capacity of wireless broadband access,mesh routers in WMN are often needed to equip with several radio interfaces and uses a number of orthogonal channels.Interference and collisions may be reduced in recent channel allocation schemes,but can not be completely avoided.A centralized inter-cluster scheduled interface-clustered channel assignment（ICCA） scheme is designed to completely eliminate interference and collisions in order to enhance network throughput.It can reduce the transmission delay that is especially fit for real-time services.
