Performance Evaluation of Connection Admission Control for IEEE 802.16 Networks

Quality of Service (QoS) provisioning to the various kinds of network traffic is one of the major design criteria of IEEE 802.16 WiMAX standard. The MAC and physical layers of 802.16 standards are designed to support different types of real time application by providing QoS. Scheduling, Connection Admission Control (CAC) and traffic policing are the major issues to ensure QoS. In standard, sche...

An Efficient Connection Admission Control Mechanism for Ieee 802.16 Networks

In WiMAX network, Connection Admission Control (CAC) plays an important role in providing QoS guarantee [47]. The multimedia services are supported in IEEE 802.16 using connection admission control (CAC), packet scheduling, dynamic subcarrier assignment etc. It provides QoS guarantee between Base Station (BS) and Subscriber Station (SS) [21]. The CAC algorithm provides bandwidth guarantee and a...

Performance Analysis of Connection Admission Control Scheme in IEEE 802.16 OFDMA Networks

IEEE 802.16 OFDMA (Orthogonal Frequency Division Multiple Access) technology has emerged as a promising technology for broadband access in a Wireless Metropolitan Area Network (WMAN) environment. In this paper, we address the problem of queueing theoretic performance modeling and analysis of OFDMA under broad-band wireless networks. We consider a single-cell IEEE 802.16 environment in which the...

Connection Admission Control Modelling for Atm Networks

The Connection Admission Control(CAC) is part of ATM traffic control and consists of a framework that optimizes network usage while ensuring the desired QoS for the services. The CAC approach we propose for ATM networks is based on a effective bandwidth allocation strategy. This paper addresses the effective bandwidth computation based on a probabilistic model for cell level QoS and call level ...
