Ad-hoc networks are flexible, self-configurable, easy and fast to deploy. Research has been done mainly in the area of routing and for isolated ad-hoc networks. Some efforts are on the way to connect ad-hoc networks to the Internet. It is however important to support QoS aware multimedia applications in this environment. Therefore, a QoS architecture for ad-hoc networks is necessary that can interwork with infrastructure based QoS approaches. In this paper, we demonstrate our approach that extends SWAN and provides QoS support for communication between ad-hoc nodes and nodes located in the public Internet. The gateway, which provides Internet connectivity to ad-hoc nodes, is also responsible for QoS signaling Interworking and participates in admission control decisions and traffic regulation
