Next generation of wireless cellular networks aim at supporting a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). Resource allocation and call admission control (CAC) are key management functions in future 3G and 4G cellular networks, in order to provide multimedia applications to mobile users with QoS guarantees and efficient resource utilization....

The Next Generation Network (NGN) is to deliver anything, anytime anywhere with full quality of service (QoS) guarantees. The network designers need to overcome the NGN’s challenges namely; heterogeneous wireless access environments, multiple traffic types, flexible bandwidth allocation and cross layer design issues among others. To guarantee quality of service for these NGN’s, a call admission...

Call admission control is a key element in the provision of guaranteed quality of service in wireless networks. The design of call admission control algorithms for mobile cellular networks is especially challenging given the limited and highly variable resources, and the mobility of users encountered in such networks. This article provides a survey of admission control schemes for cellular netw...

IEEE 802.16e Broadband Wireless Access (BWA) technology is one of the most promising technologies for broadband access and has many applications. In order to meet the requirements of diverse multimedia services, it is necessary to provide quality of service (QoS) guarantee. Call Admission control plays an important role in QoS provisioning for wireless communication systems [1–2]. However, IEEE...

AbmuctTraditional CAC schemes that mainly focus on the trade off between new call blocking probability and handoff call blocking probability can not solve the problem of congestion in wireless networks. In this paper we investigate the role of pricing as an additional dimension of the call admission control process in order to efficiently and effectively control the use of wireless network reso...

In 4G networks, call admission control techniques have been proposed to provide Quality of Service (QoS) in a network by restricting the access to network resources. Power control is essential in call admission control in order to provide fair access to all users, improve battery lifetime and system performance. But the existing call admission control algorithms rarely consider the power contro...

This paper proposes a simple but effective admission control algorithm for integrated services packet networks. The admission control scheme, based on stochastic control, aims at ensuring user discrimination, by enforcing different call blocking probabilities. The queueing behavior of reservations is analytically characterized in the absence of admission control. From this, call blocking probab...
