Evaluation and Analysis of Connection Admission Control for QoS in Wimax Networks

Abstract

IEEE 802.16/WiMax is one of the emerging as well as promising wireless technologies. Although wireless technology like WiMax has many features such as mobility and cost effectiveness etc. but it also has the issue like limited resources and QoS that necessitate the better mechanism to provide the solution. Among the other mechanism Connection Admission Control is one of the effective mechanisms for better QoS in wireless network. The main idea behind the connection admission control is to maintain the QoS in the WiMax networks. The algorithm of connection admission control works based on condition whenever condition is satisfied it accepts the request for new connection otherwise it rejects. In the wireless network like WiMax, distinct kinds of applications need distinct requirement of QoS that necessitate the CAC. This thesis presents the theoretical concept on the CAC in the WiMax networks for better QoS. This report also presents two different approaches proposed by the researchers and compares, evaluates and analyzes them on the base features of the algorithm and result obtained by the researchers. Finally shows some area for future work of the two approaches.
