Adaptive Admission Control for next Generation Networks

This paper investigates the adaptive local resource reservation call admission control protocols. The algorithms are built upon the concept of guard channel and we use an adaptive algorithm to track the optimal number of guard channel resources to reserve at a base station. We compare the following adaptive algorithms, one based on the Wiener prediction theory and the other based on the arrival rates of the handoff calls. We compare the methods together with the conventional fixed guard channel in terms of the handover blocking probabilities and the new call blocking probabilities. Our simulation results show that both these methods perform better than the fixed guard channel reservation scheme.
