A New Channel Assignment Algorithm in Multi-radio,Multi-channel Wireless Mesh Networks
Yunpei Chen · Communications technology · 2009
Wide-area wireless broadband access is poised to become ubiquitous. An important factor determining the success or failure of such an approach would be the availability of inexpensive backhaul bandwidth. n this paper, a new wireless mesh backhaul network configured with multiple radios, multiple channels, and directional antennas, is designed. A new and optimized algorithm based on the equivalent transformation of the connection graph is proposed to solve the channel assignment in the wireless mesh backhaul network. Simulation shows that the proposed channel assignment algorithm in this paper can effectively reduce the link interference and greatly improve the network performance.
