Interference-Aware Channel Assignment with Seamless Multi-Channel Monitoring on Wireless Mesh Network

The wireless mesh networks (WMNs) are statically deployed on heterogeneous areas and are operating in open wireless media, and thus it coexists with other networks operating on the same frequency with the same or different radio access technology (RAT). The WMNs experience two types of interferences according to the source of interference. Coexisted networks with WMN induce the interference called external interference and nodes in WMN experience interference each other, which is called internal interference. The increased interferences can degrade the performance significantly. To resolve this coexistence problem, we propose three channel assignment schemes for hybrid multi-channel protocol (HMCP) by recognizing the states of each channel and selecting its operating channel.
