Abstract

We nominate a weighted service queuing approach, each service queue is allotted a preset priority weight and Call Admission Control scheme for service classes defined in IEEE 802.16 standard. Different group of queues have been implemented to transmit different service classes. Allocation of bandwidth usage of each service classes are relying on maximum data that could take part in connection between different networks. The Quality of Service is achieved by considering throughput and delay as a major parameters along with the corresponding service classes taken into account. The scheduled CAC model with the token bucket mechanism allows increasing the performance of Quality of Service for multimedia services. By applying the weighted queuing approach, the acceptance of new connection request is increased to achieve the better Quality of Service in multimedia services over next generation wireless networks.
