Extending SWAN to Provide QoS for MANETs Connected to the Internet

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.
