A QoS guaranteed hybrid channel assignment strategy

These different applications require different QoS (Quality of Service) guaranteed in wireless mesh networks, such as IP telephone, video conference, video on demand (VOD), remote education and other real-time multimedia business, e-commerce. In order to achieve the satisfactory performance in WMNs, we put forward a QoS guaranteed hybrid channel assignment strategy for a multi-Interface wireless mesh network. It adopts fixed channel for the GAs node, dynamic channel for RC node, the channel assignment algorithm according to the node of traffic load and channel contention degree The number of slots assigns to the client nodes will be dynamically changed according to the service level. The strategy can achieve the satisfactory performance in.
