چکیده
In todays wireless networks different wireless multimedia services have diverse bandwidth and QOS requirements, which need to be guaranteed by the wireless cellular networks. The decision to admit or reject the new user call is made by the call admission control algorithm.In this paper, a novel Call Admission Control algorithm for wireless cellular networks is proposed. The call admission control algorithm is based on power control. It determines the optimum number of admission users with optimum transmission power level so as to reduce the interference level and call blocking. By our simulation we show that our proposed call admission control algorithm reduces the blocking probability. GJCST Classification: C.2.1 Performance analysis of Call Admission Control algorithm for Wireless Multimedia networks Strictly as per the compliance and regulations of:

Adaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...

In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...

We propose a framework for quality-of-service (QoS) provisioning for multimedia services in next generation wireless access networks. This framework aims at providing a diier-entiated treatment to multimedia traac ows at the link layer, which can be broadly classiied as real-time (or delay-sensitive) and non-real-time (or delay-tolerant). Various novel schemes are proposed to support the diiere...
