Channel Assignment on Wireless Mesh Network Backbone with Potential Game Approach
The Wireless Mesh Network (WMN) has already been recognized as a promising technology as broadband access network from both academic and industry points of view. In order to improve its performance, research has been carried on how to increase the number of simultaneous transmissions in the network while avoiding signal interference among radios. Considering WMNs based upon IEEE 802.11 b/g standards, lately most of researchers have been relying on the usage of orthogonal channels for solving the Channel Assignment (CA) problem. However, in this paper, the authors introduce a novel CA algorithm exploiting Partially Overlapped Channels (POC) that overcomes the common orthogonal channel approach. This algorithm is derived based on Game Theory framework using Potential Games and yields near optimum CA.
