Multiple Radio Channel Assignment Utilizing Partially Overlapped Channels
Source: University of Alabama
Existing channel assignment algorithms designed for Multi-Radio Multi-Channel Wireless Mesh Networks (MRMC-WMN) mainly deal with orthogonal or non-overlapped channels. But in reality, the limited availability of orthogonal channel is a major issue where the network is very dense in terms of inter-nodal distances. On the other hand, Partially Overlapped Channels (POC) are currently considered as a great potential for increasing the number of simultaneous transmissions and eventually upgrading the network capacity; especially in case of MRMC-WMN. In this paper, the authors address the limited orthogonal channel problem by exploring the usable POCs. The key technique lies in the fact that the interference between adjacent channels has to be considered intelligently in order to increase the overall capacity.
