چکیده (انگلیسی):

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.
