Connection admission control for PCS-to-Internet protocol internetworking

This paper studies the connection admission control for PCS-to-Internet protocol internetworking. In order to provide QoS to the Internet while avoiding the scalability problem, several recent papers proposed using an endpoint measurement-based admission control (EMAC) scheme, in which one end host sends probe packets and the other end host makes the admission decision based on the collected result. Although EMAC has many desirable features in wireline networks, we show in this paper that several distinct characteristics of mobile wireless networks make EMAC difficult to implement. On the other hand, third generation (3G) wireless networks will have their own connection admission control functions. We propose a mobile EMAC (M-EMAC) scheme for PCS-to-IP internetworking, and present simulation results to show that M-EMAC outperforms EMAC
