Abstract

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 802.16e standard does not specify the CAC scheme at all. In this paper, a novel call admission control scheme is proposed for 802.16e networks based on maximum use of subchannels using AMC to minimize the overall transmit power in OFDMA systems for low, medium and heavy multimedia traffic .the results clearly indicates the performance the novel call admission control algorithm to show the effectiveness of bandwidth estimation and resource allocation using this novel CAC algorithm over that of dynamic bandwidth allocation call admission control (CAC).
