DySSCo - A Protocol for Dynamic Self-Organizing Service Coverage

Service oriented middleware draws a lot of attention in current research on sensor networks. The automatic distribution of services within a network and the preservation of this distribution is a fundamental aspect of network applications with self-x properties. The network gains the ability to react on mobility, network fragmentation, node failures and new user demands. This paper proposes a distributed selforganizing algorithm for service distribution and preservation of this distribution using demanded coverages for the services. After discussing the theory of the convergence of the algorithm, this paper presents a real-world deployment of a sensor network scenario and evaluates the performance of the algorithm.
