In this paper we build on methods from probabilistic management for overcoming two issues in the translation of QoS into configurations of network nodes in dynamic, decentralized, and hierarchical networks. First, the inherent uncertainty about node performance in such networks (due to network dynamics) may impede adequate specification of QoS. We suggest how a probabilistic variant of QoS via optimization can be translated into objectives that can be handled with probabilistic management methods. Second, the dynamics of the network may make the interpretation of QoS dependent on the availability of network resources. We use methods from probabilistic management to suggest how the expression of QoS may be restricted in order to be able to ensure the existence of a translation of given QoS. The suggestions are applied to our own network architecture. The aim is to further develop our approach to a viable management solution for cloud computing and virtualized networks.
The Analytic Hierarchic Process (AHP) is used for presenting a method for setting up policies that define priorities among services sharing a limited measure of bandwidth in an ad-hoc radio network. We examine the issue of ensuring the autonomy of the users of the bandwidth, as well as the issue of ensuring that the priority policies result in efficient bandwidth usage even when the priority decisions involve uncertainty about the dynamics of the network and the services.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
