Wireless Call Admission Control Using Threshold Access Sharing
نویسندگان
چکیده
This paper presents a call admission control (CAC) algorithm that aids in the Quality of Service (QoS) support in a wireless network base station. The Threshold Access Sharing (TAS) scheme provides improved performance over generalized methods of current CAC algorithms. The TAS algorithm relies on a prioritization of admitted traffic through bandwidth thresholds. This is particularly vital for high priority real-time calls and preapproved QoS handover calls. In addition, the CAC algorithm must rely on some advanced levels of channel estimation to most effectively use the limited channel resources.

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...

Abstmet-This paper addresses the issue of call admission control with the necesary QaS guarantee for a micddala integrated wireless cellular network. Specifically, we propose a new call admission control policy called Dual-Threshold Call Admission Conml (DT-CAC) policy. It uses hw rhresholdr, one to reserve channels for narrow-band voice handoffcalls, and the other for wideband data handoff Irf...

In this paper model of integrated voice/data cellular wireless networks (CWN) are investigated. The unified approximate approach to calculate the desired Quality of Service (QoS) metrics in an isolated cell of such networks under two multi-parametric call admission control (CAC) strategies is developed. One of them is based on the guard channels scheme while the second is based on a threshold s...

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...
