An adaptive algorithm for call admission control in wireless networks

In the present paper, we develop an adaptive algorithm for call admission control in wireless networks. The algorithm is built upon the concept of guard channels and it uses an adaptation algorithm to search automatically the optimal number of guard channels to be reserved at each base station. The quality of service parameters used in our study are the new call blocking probability and the handoff call blocking probability. Our simulation studies are performed for comparisons of the present algorithm with static guard channel policy. Simulation results show that our algorithm guarantees that the handoff blocking rate is below its given threshold and at the same time, minimizes the new call blocking rate.
