Connection admission control in a cellular wireless ATM access network

A virtual connection tree (VCT) concept has been proposed to avoid the need to involve the network call processor for every cell handoff attempt in cellular ATM networks. Acampora and Naghshineh (see IEEE Journal on Selected Areas in Communications, vol.12, no.8, p.1365-75, 1994) propose a model for connection admission control (CAC) to the virtual connection tree is for a homogeneous system. With wireless ATM perceived for supporting multimedia services, it is necessary to consider heterogeneous traffic models. We propose two CAC approaches for admission to the VCT based on equivalent capacity for heterogeneous traffic. We study the performance of one of these approaches by mathematical analysis and the other approach by computer simulation. The quality of service performance are the overload probability in a base station and the % overload period in a base station
