In: Proceedings of the 2009 IEEE International Symposium on Modeling Analysis and Simulation of Computer and Telecommunication Systems (MASCOTS), (Jeremy T. Bradley, James M. Conrad, A.J. Field, Uli Harder, William J. Knottenbelt, George F. Riley Ed.), pp. 311--218, 2009.

Abstract: Ensuring Quality of Service (QoS) in wireless networks poses an open problem in many application domains. We propose an automatic on-line QoS monitoring and management infrastructure that can be incorporated into existing network setups. Based on model-based assessment of current and future QoS conditions, our solution will control traffic in the network through a combination of admission control, enforced hand-over, traffic shaping and transmission parameter adjustments. Correctness of the model is evaluated through experimental evaluation and simulations. We implement a prototype of the proposed system using open-source components.
