Abstract

As the features of service composition such as large scale, high complexity, various failures and resource dynamics, a safe and credible service composition scheme is one of the biggest challenges for flexible deployment and on-demand providing. Based on the critical analysis of block chain infrastructure, consensus mechanism and programmable features, contrasting to the characteristics and process of Web service composition, this paper developed an novel service composition system architecture with much more credibility and reliability using service overlay networks theory. In addition, considering the security strategies derived from block chain consensus mechanism, and making full use of smart contract's functions and effects, this paper proposed an effective algorithm based on the predictive route life time(RLT) and service intensity(SI) across overlay networks for the generation of service paths. Besides, it designed a better service-path selection algorithm which was decided by the trusted quality of service model with the single-node's trust index and interactive tightness index. The simulation results show that the service composition strategy based on block chain mechanism has greatly increased the success rate and credibility of service components after composition.
