Multi-radio multi-channel

Latin squares

Novel channel

We have presented the two types of channel assignment schemes and routing methods: Latin squares based M4 approach and Novel channel assignment approach, for MRMC communication. The novel optimal efficient channel assignment scheme can greatly relieve the interference effect of close-by transmissions; effective routing schemes can alleviate potential congestion on any gateway to the Internet, thereby improving per-client throughput.The channel assignment in multi-interface WMN consists of a task to assign channels to the radio interfaces by such away to achieve efficient channel utilization and minimize the interference. Simulation results conclude that the proposed effective channel assignment scheme will improve the Quality of Service (QoS) in wireless mesh networks by improving throughput, packet delivery ratio and by reducing end-toend delay compared to Latin squares based M4 approach and IEEE 802.11e.
