Adaptive admission control algorithm and performance analysis in wireless/mobile networks
Zhao A-qun · Journal of China Institute of Communications · 2004
In wireless/mobile networks, new connection blocking probability(CBP) and handoff connection dropping probability(HDP) are important connection level QoS parameters. Forced connection terminations due to handoff connection dropping are generally more objectionable than new connection blocking. In general, most of the previously proposed schemes for reducing handoff connection dropping probability substantially at the expense of increasing the new connection blocking probability and decreasing the utilization of the cells by reserving channels exclusively for handoff connection requests. Recently there is a growing interest in the adaptive multimedia application where the bandwidth of an ongoing multimedia connection can be dynamically adjusted. In this paper, we research multi-priorities services adaptive admission control mechanism, present a adaptive admission control algorithm, and analyze its QoS performance.
