Framework for Dynamic Resource-Constrained Service Composition For Mobile Ad Hoc Networks

Gerald Kaefer, Reiner Schmid, Guenter Prochart, Reinhold Weiss

چکیده

In this paper we present a framework for dynamic resourceconstrained composition in mobile ad hoc networks (MANETs) in order to manage the permanently changing environment by reason of mobility and resource variability. Moreover, dynamic composition alone is not sufficient because devices could typically be very resource-constrained and the resource situation may change rapidly, e.g. battery power may fade away, or due to memory limits a service may not currently run on a device, though it is available in principle. The described framework provides two novel aspects: First, the framework provides automatic execution of dynamic compositions for endto-end functional descriptions even if functional nodes contained in that description are not directly compatible. Second, the framework approaches resource optimization based on simple rules, but with powerful means, such as deployment provisioning and migration of services and components within an ad hoc network.
