Abstract

A probability-based adaptive algorithm for call admission control in wireless network is proposed and validated. The algorithm is somewhat similar to that of RED (random early detection), which is based on probability to control the guard channels according to controlled QoS measure. The QoS measures studied are call-blocking probability, handoff-call blocking probability and system utility. Simulations are compared to study the performance of the probability-based algorithm, the guard channel algorithm, and the adaptive algorithm devised by Yi Zhang. And results show that the probability-based algorithm outperforms the latter two algorithms in QoS measures.
