Resource Allocation Management for Multimedia QoS in Wireless Networks

Adaptive resource allocation for multimedia quality of service (QoS) support in broadband wireless network is examined in this work. A service model consisting of three classes with different handoff dropping requirements is presented. Appropriate call admission control and resource reservation schemes are developed to allocate resource adaptively to the real time service classes with stringent delay bound. An efficient and effective measurement based dynamic resource allocation scheme is proposed for prioritized services. The non real time application serviced by the best effort model, are supported. The system accommodates adaptive multimedia applications to further reduce the blocking and dropping probabilities of real time application. The simulation results show that the proposed system can satisfy desired QoS of multimedia application under different traffic loads while achieving high channel utilization.
