Paper Abstract

An adaptive system to support multimedia applications in a wireless network environment is investigated in this research. The proposed system is hierarchical in nature with a cluster of mobile end-hosts connected to a base station, and base stations are connected to a supervisory node, which is in turn connected to a wired infrastructure. Based on our previous experience, the system is designed with an improved service model and a novel call admission scheme that enables more efficient radio channel usage. The service model takes into account both user mobility and the nature of multimedia traffic. Specifically, delay- and/or rate-adaptive services are explored to increase the network performance and utilization under highly variable network connectivity and transmission capacity. The new call admission control scheme is developed under a hybrid call admission control framework. Together with an adaptive resource reservation scheme, it can be adapted to the network situation as well as application requirements. Simulation studies are conducted to show the performance improvement of the proposed scheme.
