Performance Evaluation of a Wireless LAN Dynamic Multi Channel Allocation Strategy

This paper presents a Per-Packet Dynamic Channel Allocation algorithm with QoS support to be applied in a wireless multichannel environment. The strategy has been studied both in a simulative and in a more general analytical perspective. The results, concerning the packet drop probability D and the average number of used channel per non dropped activity U, show a high system efficiency in the resource use, with the possibility to be increased by simply grow the number of available channels; measured trend results linear and this indicates that quite good performance may be obtained by the system really outperforming the classical not cooperative solutions
