Quality of service for rapidly deployable radio networks

We present an end-to-end QoS provisioning mechanism for a rapidly deployable radio network (RDRN). A flow specification tailored for a highly dynamic mobile networking environment is proposed. The instability of wireless links and the mobility of the nodes influence the flow specification. A flow establishment scheme that uses in-band signaling to establish the flows is described. This approach is designed to make efficient use of the features of IP at the network level and ATM at the link level. In the event of non-availability of the requested QoS, the flow establishment scheme constantly attempts to scale up to the maximum requirements of the application, and establishes the flow when the resources become available. A QoS architecture for an RDRN system is also proposed, which provides the framework for the configuration, prediction and maintenance of the end-to-end QoS.
