Abstract:
Recently, the advance of service-oriented architectures and peer-to-peer networks has lead to the creation of service-oriented peer-to-peer networks, which enable a distributed and decentralized services market. Apart from the usage of single services, this market supports the merging of services into new services, a process called service composition. However, it is argued that for the time being this process can only be carried out by specialized peers, called service composers. This paper describes the new market created by these service composers, and models mathematically building blocks required for such a service composition. A general algorithm for service composition developed can be used independently of solutions for semantic difficulties and interface adaption problems of service composition. In a scenario for buying a distributed computing service, simulated strategies are evaluated according to their scalability and the market welfare they create.
