Abstract In Wireless Local Area Networks (WLANs), co-channel deployment is desirable for mitigating the collision and interference among different access points (APs). Therefore, it can bound channel access delay and improve network capacity. In this paper, we present an interference model for multiple APs co-channel deployment. And then we formulate the channel assignment problem into a time slot allocation problem and propose a co-channel assignment strategy, which includes two procedures: (1) Assigning the channel based on the vertex coloring algorithm. (2) Making extra polls to improve the channel assignment by applying time slot reservation strategy. The simulation results show that our proposed algorithm can improve the network throughput and transmission delay by 8% and 15% respectively compared with the TMCA scheme.
