Call admission scheme based on estimation of call dropping probability in wireless networks

摘要

An effective call admission control scheme is proposed in order to solve the problem due to handoff. The proposed call admission control is based on estimation of call dropping probability. When a new call is generated, the proposed scheme estimates the call dropping probability of the cell where the new call exists and accepts the call only when the estimated probability does not exceed a certain value of threshold set in advance. By computer simulation, we evaluate the call blocking probability and the call dropping probability of the proposed scheme and show the effectiveness of the proposed scheme.
