A dynamic connection admission control scheme for wireless multimedia communication networks

In this paper, a novel dynamic connection admission control scheme is proposed to provide QoS guarantees in high-speed cellular networks carrying multimedia traffic. This scheme provides QoS level by limiting the maximum threshold of handoff connection dropping probability for real time traffic and periodically adjusting the size of reservation pool according to rapidly changing network load conditions. Extensive simulation results reveal that our scheme is very simple and easy to implement, and features very low connection dropping probability, the nearly same high bandwidth utility with fixed reservation scheme, with a price of little higher of connection blocking probability.
