摘要：

In this paper we propose the channel assignment scheme for multi-channel wireless mesh network (WMN), where each mesh router is equipped with multiple radio interfaces. In real WMN the number of radio interfaces is much higher than the number of non-overlapping channels, which causes a lot of connections between mesh nodes operate on the same radio channel. Increasing number of simultaneous transmissions on the same channel causes interference, which limits network capacity. This paper presents a new centralized channel assignment scheme called first random channel assignment algorithm (FRCA). This algorithm efficiently utilizes radio interfaces to achieve improvement of the network capacity. NS-2 simulator was used to evaluate the performance of proposed solution and simulation results were compared with others channel assignment algorithms.
