A Load Management Algorithm For Wireless Mesh Networks
Ilyas Bambrik, Fedoua Didi · 2015
The WMN (Wireless Mesh Network) is a new emerging technology that can render the field of industrial network more efficient and profitable. Due to its versatility that allows a flexible configuration, this kind of network is commonly considered as a very suitable architecture for mobile clients. The difference between the WMNs and other dynamic networks, such as the MANET (Mobile Ad-hoc Network), is that the Mesh network contains static wireless nodes called MR (Mesh Routers). Consequently, the presence of this infrastructure makes the WMN more suitable to provide QoS (Quality of Service). However, the guarantee of QoS in a dynamic topology is a difficult task by comparison with static networks. These difficulties are caused by the random movement of the clients, the shared nature of the wireless channel, the complexity of multi-hop communications and most importantly the management of the traffic load forwarded through the MRs. In this paper, we propose a new algorithm for load balancing in WMN that can search for alternative paths in order to deviate from the loaded MRs. The proposed algorithm can operate with different metrics at the same time and applies the Genetic Algorithm in case there is a large population of possible solutions.
