Interference Aware Spectrum Allocation in IEEE 802.22 Wireless Mesh Networks

Abstract

This research studies the current IEEE 802.22 system architecture and investigates the limitations in creating wireless back-haul mesh networks due to its lack of knowledge about the spectrum bands to be used. In this regard, a coordinated distributed scheme for IEEE 802.22 enabled devices to is proposed establish a mesh network with reduced interference. The coordination is initiated by the base station and is followed by the iterative joining of the IEEE 802.22 consumer premise equipment to the mesh network in a distributed manner. A graph coloring approach is taken, and an algorithm called Maximum Utility Graph Coloring (MUGC) is proposed to allocate spectrum to the mesh network, enabling higher spectrum utilization and reduced collisions. Two objective functions are explored: maximize utility and proportional fair utility to allocate spectrum efficiently.
