A Bounded-time Service Composition Algorithm for Distributed Real-time Systems

Service Level Agreements (SLAs) are nowadays used as a cornerstone for building service-oriented architectures. SLAs have been closely investigated in the scope of distributed and Grid computing and are now gaining uptake in cloud computing as well. However, most solutions have been developed for specific purposes and are not applicable generally, even though the most approaches propose a general usability. Only rarely have SLAs been applied to real-time systems. The purpose of this chapter is to analyze different fields where SLAs are used, examine the proposed solutions, and investigate how these can be improved in order to better support the creation of real-time service-oriented architectures.

Effective Service

The service composition process depends on effective service discovery, matching, and selection. Although, service discovery and matching has been thoroughly researched for software services, an effective service discovery and matching mechanism is needed for services representing device functionality. In this chapter, an ontology-based service description method and service discovery and matching mechanism is proposed for Distributed Embedded Real-Time Systems (DERTS). For service description, the existing ontology specification OWL-S is modified to make it suitable for DERTS. The proposed mechanism was applied to a scenario of Smart Home case study for testing. The proposed service description method and discovery and matching mechanism set foundations can be used for the dynamic service composition in DERTS and in any ubiquitous environment.
