Service Composition in eHome Systems: A Rule-based Approach

Abstract

This paper deals with eHome systems. We focus on theservice composition in order to reduce complexity and to leverage maintainability and extensibility of eHome services. Talking about services, we mean any piece of software, which is executed in a network environment, making the usage and administration of ubiquitous appliances easier. Current situation is, that the complete functionality is hard-coded into services without the facilities to be extended or reused. Many logical correlations (e.g., how to react if an alarm condition is raised) are made explicit in an inappropriate way. To tackle this problem, we introduce a declarative approach to specify logical correlations and to combine functionalities and services to new services, offering the required flexibility and comprehen-
