Resource allocation in OFDMA wireless mesh networks

A wireless network with a mesh topology works reliably and offers redundancy. In modern broadband wireless mesh networks using OFDMA techniques, the problems of time, frequency, are more complicated from a cellular system, due to system architecture and distributed control and management. This paper focuses on OFDMA wireless mesh network systems and the problem of time/frequency resource allocation, particularly with regard to subcarriers. Advanced graph theory tools are used for time/frequency resource allocation in an arbitrary architecture using to and for a square grid allocation and allow frequency reuse.
