Abstract: This paper investigates the challenges involve in designing a dynamic channel assignment (DCA) scheme for wireless mesh networks, particularly for multi-radio systems. It motivates the need for fast switching and process coordination modules to be incorporated in DCA algorithm for multi-radio systems. The design strategy is based on a reinterpretation of an adaptive priority mechanism as an iterative algorithm that recursively allocate a set of channels to radios in a fair and efficient manner in order to minimise interference and maximise throughputs. The algorithm, called Adaptive Priority Multi-Radio Channel Assignment (APMCA) is tested for overall performance to assess the effectiveness by determining its overall computational complexity. The combined advantages of fast switching time and process coordination modules make the APMCA a useful candidate towards automating the channel assignment method in multi-radio wireless mesh network planning and design.
