Abstract :
In this paper, we present two simple-to-implement measurement-based admission control methods for real-time services in IEEE 802.16e networks. The first method simply utilizes the averaged number of free slots as input in admission decisions while the second method is more advanced and it tunes the admission thresholds according to current traffic load. Our simulations show that the proposed methods lead into more efficient use of scarce radio resources-without sacrificing the quality of service (QoS) requirements - than using parameter-based, i.e., static, connection admission control.
