Wireless Environments

With the emergence of powerful mobile Internet devices such as smartphones, mobile devices are expected to play the role of service providers or even brokers, as well as clients. However, the frequent mobility of devices and the intermittent disconnection of mobile and wireless network may degrade the availability and reliability of services. To resolve these problems, this paper proposes an efficient method for migrating and replicating Web services among mobile devices. Specifically, the proposed method splits the source code of a Web service into subcodes depending on users’ preferences for its constituent operations. For the seamless provisioning of services, a subcode with a higher preference is migrated earlier than others. To evaluate the performance of the proposed method, the effect of the code splitting on migration was analyzed.
