摘要：

Service composition in pervasive environments enables users to utilize services in the environment to solve complex queries. Current work in development of service composition architectures focuses on wired-networked environments where solutions are centralized and tailored towards a reliable network and fixed service topology. In this paper, we present an alternate and novel design architecture of a broker-based distributed service composition protocol for pervasive environments. We present simulation results by comparing our protocol to a centralized architecture for composition. Results show that our distributed broker-based composition architecture perform better than the centralized solution in terms of composition efficiency, broker arbitration efficiency and composition radius.
