Performance evaluation of a distributed call admission control for QoS-sensitive wireless mobile networks

This paper presents a performance evaluation of a distributed call admission control framework developed for cellular mobile networks. The call admission control algorithm involves not only the original cell (handling the new admission request) but also a cluster of neighboring cells. 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 provided to show the improvements obtained using our framework
