Efficient Resource Management for Distributed Applications with Real-Time Requirements in Broadcast Networks

8th CaberNet Radicals Workshop, 2003.







Abstract

Distributed applications are often established in local, e.g. wireless, networks. An important means to guarantee an acceptable quality of service in networks with real-time communication requirements is the reservation of resources at connection setup time. However, such reserved resources, e.g. transmission bandwidth, may be unused as a consequence of the variations in the actual resource demands. Indeed, in many, mainly wireless, networks these resources are quite limited. Therefore, we propose a more efficient resource utilization which is possible if communicating stations or end-users dynamically hand over some of the free resources temporarily to the other communication partners, e.g. of a "broadcast network".

This paper summarizes some of our main results as achieved up to now. We focus on our recent work in progress as well as on future prospects of such a demand-based sharing of resources: on the one hand, estimation of the current resource requirement on the basis of load measurements is discussed and, on the other hand, we present efficient algorithms for resource sharing respecting real-time requirements. Our approach suggested for resource and traffic management allows one to achieve significantly better utilization of network resources which is demonstrated by means of examples.
