Adaptive Admission Control for MBMS satellite system

Abstract

This paper is focused on the design of an adaptive Connection Admission Control (CAC) framework for a Multimedia Broadcast Multicast Service (MBMS) compatible satellite system. The main feature of the proposed framework is the ability to maximize the resource utilization by adapting to the link conditions of the users. The link quality of the user may vary depending on the weather condition, user mobility and any other propagation factors. The framework also features the ability to admit a higher priority connection by pre-empting an existing lower priority connection for multimedia traffic with varying bandwidth requirements. The proposed CAC framework is simulated using MATLAB and the performance results are obtained for a mix of multimedia traffic classes such as videostreaming, webbrowsing, netted voice and email.
