Broadband Wireless Networks is growing rapidly due to the increased number of mobile users. The greatest challenge is to achieve maximum throughput with minimal or no interference while performing concurrent transmission. To reduce the interference problem, this paper proposes a cooperative scheduling and channel assignment algorithm for multi-channel wireless mesh networks. In scheduling algorithm, to avoid the primary interference, the proper time slot is assigned through centralized scheduling for the packet and link in a network. The objective of using the scheduling algorithm is to reduce the transmission delay for uplink/downlink networks. Channel assignment algorithm helps to avoid secondary interference and to perform concurrent transmission with an optimal number of channels. In scheduling, the priority of packets contributes to preventing the accumulation of packets and transmission delay in a multi-hop network. Simulation analysis shows that our channel assignment algorithm avoids both interferences with an optimal number of channels.
