Abstract—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
