Paper Abstract

Supporting end-to-end QoS of media streaming applications over wireless Internet has received tremendous interest recently. In this paper we propose a new architecture for transmitting real-time multimedia streams over Bluetooth wireless Internet integrated with Differentiated Services (DiffServ) mechanism. IP support over Bluetooth is discussed in details to take advantage of the DiffServ framework. In our proposed architecture, the Bluetooth wireless users are connected to the Bluetooth LAN Access Point to acquire the capability of Internet access. Different media streams are classified at edge routers of the DiffServ core network, mapped to different priorities and delivered according to the dynamically negotiated Service Level Agreement (SLA). QoS monitoring agents deployed in network nodes and endsystems can monitor network QoS conditions and provide reports to the concerned nodes. Implementation details of the prototype of the proposed architecture are given in this paper. Specially, the Bluetooth communication is implemented as a virtual network card that supports IP protocol in order to provide consistent access to the DiffServ Internet. Experimental results show that enhanced end-to-end QoS can be achieved based on our architecture.
