Abstract

In wireless multimedia networks, the process of offering Quality of Service (QoS) guaranteed multimedia services becomes more challenging owing to the limited bandwidth, dynamic environment and mobility. This problem can be overcome by a call admission control mechanism that restricts the network access based on resource availability. In this paper QoS based Adaptive admission control algorithm for wireless multimedia networks is proposed. Initially the calls entering the network cell are categorized as real time handoff calls, non-real time handoff calls and new calls which are handled in the similar progression. In common, any call category entering the cell undergoes bandwidth test and when the bandwidth value is satisfied, the call is admitted. Otherwise cell performs different cell resizing technique for respective call categories. The proposed work is implemented in Network simulator (NS-2). It is shown that the proposed admission control algorithm achieves better bandwidth utilization, fairness with reduced call dropping rate, when compared with the existing technique. A mobile cellular architecture based on WCDMA is considered for implementation of this technique.
