In wireless multi-hop networks, broadcasting by flooding generates frequent retransmissions of unnecessary packets that participate heavily in increasing contention and collision probability. These problems become increasingly likely in a wireless mesh network which can interface to other external networks, thus leading to a significant increase in broadcast traffic. In this paper we have focused...
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...
