Performance Analysis of a Simplified Call Admission Control Scheme for Multimedia Wireless Network

چکیده
One of the key mechanisms for QoS provisioning is the call admission control, which manages system resources based on application QoS requirements. To address the QoS provisioning issue in the multimedia wireless network, we have proposed a conservative and adaptive QoS (CAQoS) provisioning model. CAQoS is designed to optimize the existing CAC scheme based on two parameters, which are the conservative rate and bandwidth scale-down rate. In this paper, we highlight the novelty of the proposed CAQoS and investigate its performance impact under different conservative and bandwidth scale-down rates, through simulations of a realistic wireless cellular-based environment.

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...
متن کاملA Call Admission Control Protocol for Multimedia Cellular Networks
The performance of any cellular wireless network, as well as its revenue (number of customers using the network, and their degree of satisfaction) is determined to a great extent by its call admission control (CAC) protocol. As its name implies, the CAC determine if a new call request is granted, or rejected. In this paper, we propose a call admission control protocol for cellular multimedia wi...
متن کاملCall Admission Control for QoS Provisioning in Multimedia Wireless ATM Networks
In this paper, we investigate a call admission control (CAC) problem in a multimedia wireless ATM network that supports various multimedia applications based on micro/pico cellular architectures. Due to reduced wireless cell size (compared to conventional cellular networks), forced termination of calls in progress becomes a more serious problem in the wireless ATM network. Another problem speci...
