Traffic Profiling and Dynamic weight computing using dWRR for Average packet delay versus traffic load

The capacity of the conventional wireless mesh network (WMN) with single channel single radio is limited due to cochannel interference. To resolve this capacity limitation problem, multi-channel multi-radio (MCMR) protocols have been proposed. Wireless mesh networks has attractive significant attention towards promising technology. It is becoming a trend for the fourth generation of wireless mobility. Communication in large-scale wireless networks can create bottlenecks for scalable implementations of computationally intensive applications. Classes of crucially important communication patterns that have already received considerable attention in this regard are group communication operations, since these inevitably place a high demand on network bandwidth and have a consequent impact on algorithm execution times. Multicast communication has been among the most primitive group capabilities of any message passing networks. Existing solutions offered for providing multicast communications in WMN have severe restriction in terms of almost all performance characteristics. Consequently, there is a need for the design and analysis of new efficient multicast communication schemes for this promising network technology. 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.
