Abstract

Wireless self-organizing network including WiMAX (worldwide interoperability for microwave access) mesh networks can provide effective communication in pervasive computing environment. To resolve the problem that WiMAX Mesh network lacks QoS (Quality of Service) guarantee mechanism, a novel resource reservation mechanism used in WiMAX mesh network is proposed. This mechanism uses existing service classes in original standard. Protocol processes that establish dynamic service flow are defined. Using extended distributed scheduling message, the delivery method of dynamic service management messages in WiMAX mesh networks is implemented. Minislot allocation algorithm is given to support data scheduling of various services. The simulation result shows that the mechanism can provide QoS in WiMAX mesh networks effectively.
