Recently, mobile devices enabled with Web services are being considered as equal participants of the Web services environment. The frequent mobility of devices and the intermittent disconnection of wireless network require migrating or replicating Web services onto adjacent devices appropriately. This paper proposes an efficient method for migrating and replicating Web services among mobile devices through code splitting. Specifically, the proposed method split the source code of a Web service into sub-codes based on users' preference to its constituent operations. The sub-code with higher preference is migrated earlier than others. The proposed method also replicates a Web service to other devices to enhance its performance by considering context information such as network traffic or the parameter size of its operations.
