Abstract

Ad hoc network is a wireless mobile communication network composed of multiple mobile nodes and wireless transceiver devices. Considering the dynamic topology, limited resources and network instability of mobile ad hoc networks, this paper focuses on the mobility of nodes. By optimizing the selection process of service and service provider, the instability of service composition is studied to improve the reliability of service composition. A mathematical model for measuring the reliability of service composition is presented: success rate model. According to the success rate model, three algorithms are proposed: dynamic programming algorithm, improved dynamic programming algorithm and continuous maximum service algorithm to solve the corresponding service composition solution.
