Abstract

In this paper, we enhance our distributed call admission control scheme developed for cellular mobile networks. The new scheme can dynamically adapt to changes in the network load to maintain a target call dropping probability. We investigate the impact of the number of neighboring cells involved in a call admission decision in addition to the cell where the call originated. The neighboring cells provide significant information about their ability to support the new mobile user in the future. This distributed process allows the original cell to make a more clear-sighted admission decision for the new user. Simulations are presented with a detailed analysis of a comparison between two schemes involving different number of cells
