A Dynamic Multi-Threshold Call Admission Control Scheme in Wireless Networks
Hu Dan · Journal of Hunan University · 2004
For multi-traffic business in wireless networks, the paper proposes a call admission control scheme, which is built upon the concept of dynamic guard channels. The scheme sets service threshold for each traffic based on its priority, and dynamically adjusts service thresholds according to system load. Simulation results show that, compared with existing fixed schemes, the proposed scheme can not only guarantee the priority of traffic, but also maintain better performance with the real-time changes of the traffic volume.
