A Session Migration Scheme for Smart Web Services in Mobile Computing
نویسندگان
چکیده
In present times, quite a large number of network applications have been implemented as Web services to take advantage of World Wide Web, the most popular and common platform in the Internet. Although most modern mobile devices are able to connect to the Internet and hence capable of accessing Web services as stationary clients do, they often suffer from performance degradation because of the unawareness of client mobility in the protocol design. In this paper, a session migration scheme is proposed to provide persistent Web services with better service quality and improved availability by dynamically assigning the most appropriate server to each mobile client at any time instant. The proposed scheme avoids introducing extra burden to mobile clients, and the determination of the most appropriate servers can be customized to take a variety of logical and physical metrics into consideration, resulting in a practical and flexible architecture for smart Web services in mobile computing.
