Admission control for wireless multimedia networks with hard call level quality of service bounds

摘要

In this paper, a new adaptive admission control scheme for wireless cellular network supporting mixed narrowband and wideband traffic is proposed. The scheme is event-based and provides hard constraints on hand-off dropping probability requirements. The role of the quality of service (QoS) regulation parameter P_oυ in the call admission process is analyzed and presented. The analytic results are validated by simulation. We also show that the analytic model is extensible to more than two types of traffic.
