A load and QoS aware scheduling algorithm for multi-channel multi-radio wireless mesh networks

The great potential of Wireless Mesh Networks (WMNs) is their autonomy of being built and formed without the need of any infrastructure. An IEEE 802.11s standard draft has been lately designed to define the WMNs framework and architecture. Multi-channel multi-radio wireless mesh networks (MCMR WMNs) have been introduced to improve system performance. However, interfaces and channels management in MCMR WMNs becomes essential to achieve the network performances rise. In this paper, we propose a solution that defines a MAC layer module named Interface Management Module (IMM) under a hybrid channel assignment. The IMM manage the multi-channel radio interface based on scheduling algorithms. A dynamic scheduling algorithm has been proposed. The algorithm is based on traffic profiling and dynamic weights computing for channels scheduling.
