Incorporation of user preferences into mobile web service conversations

Abstract

WS-CDL (Web Services Choreography Description Language), a Candidate Recommendation from World Wide Web Consortium, facilitates the specification of rules to govern the ordering of message exchanges between web service participants. This paper considers a computing environment where a mobile client interoperates with a web service provider according to a WS-CDL specification that defines peer-to-peer interactions, and proposes a framework through which the client can specify its preference on how conversation should take place. The presented framework allows mobile clients to effectively cope with user and device mobility through providing a flexible means to reduce the number of exchanged messages without violating choreography requirement. © Springer-Verlag Berlin Heidelberg 2007.
