Abstract
With the development of network communication technology and mobile terminal equipment, mobile ad hoc network (MANET) is becoming more and more widely used. It is composed of a group of terminal equipment and routing function of the communication network composed of autonomous systems, also known as wireless ad hoc network. When the nodes located in it can move, it is called mobile ad hoc network. The mobile nodes located in the network can exchange information with each other or provide services for other nodes. In order to improve the reliability of service composition, a large number of researches focus on minimizing the number of interruptions of service composition and reorganization of service composition, but less research on the reliability of service before the service is combined. The purpose of this paper is to use the results of mobile forecasting technology to find a service portfolio with low risk of failure before the service composition is used. In this paper, a failure risk model is proposed to measure the reliability of service composition, and an algorithm is designed based on the model: single-step enumeration algorithm to solve the corresponding service composition solution, so that the service composition scheme has Smaller risks reduce the probability that a service composition will be interrupted during execution.
