Abstract: In order to raise the rate of service searching success and reduce the rate of service executing interruption, the reliability-predicted service discovery & selection protocol ( RPD&S) was proposed. A new mobile model of nodes could predict the mobility and available time of nodes, calculate the reliability of service provider nodes and the path, and then select the service provider node and the path with high reliability. Meantime, a double path was built between service request nodes and provider nodes. Simu-lation shows RPD&S can reduce failure rate of searching service and interrupt rate of execution. It also proves that RPD&S can solve the problems in service discovery and selection and improves the user expe-rience.
