An analytical model for an RIO queue fed with On/Off sources over a wireless link

The diverse nature of Internet applications gives rise to a need for a network architecture that is robust and can support a wide range of quality of service. Differentiated service is one such architecture. Although it has been the subject of much recent research, existing work focuses primarily on wired networks. As wireless networks become more important, it is necessary to examine the performance of differentiated service over these types of networks. In this paper, we analyze the performance of an RIO queue fed with homogeneous On/Off sources over a two-state Markov wireless channel. The system is used to model the provision of assured forwarding differentiated service over wireless links. A novel stepped-RIO scheme is used to provide an analytically tractable representation, and simulation results confirm the accuracy of the analytical model. Copyright © 2003 AEI.
