A tuplespace-based coordination architecture for service composition in pervasive computing environments

With increasing number and wireless connected computing elements, pervasive computing environments become more and more complex. This environment need an improved coordination mechanisms and composted services to provide the users with a sufficient level of quality. This paper introduces a tuplesapce-based coordinate service composition architecture that addresses these two requirements. Our proposal supports a high level coordination model that is based on the use of tuplespace to achieve service composition among the nodes. We use DAG-based (directed acyclic graph) algorithm to compose services efficiently. In addition, a case study is implemented and some future work is described.
