A Preference Profile for Automating Web Services Conversation in Mobile Environment

Devices, standards and software develop rapidly, but still often independently of each other. This creates problems in terms of content suitability on various devices. Also, in mobile environment, user and system-level applications must execute subject to a variety of resource constraints. In order to deal with these constraints, content adaptation is required. In this chapter, we justify the need of distributed cross media content adaptation and the potential of utilizing Web Services as the adaptation providers. We introduce request-driven context to complement constraint-driven and utility-driven approaches. We describe the request context mapping and propose a novel path’s determination scheme for determining the optimal service proxies to facilitate the adaptation tasks. To better illustrate the disjoint portions in content passing between service proxies, two communication models were associated. Then, within Web Services, we explain the related protocols and socket connection between adaptation’s services. We conclude with discussion regarding the strengths of the proposed architecture.

As the number of Mobile Web Services (MWS) with different specifications has increased, the task of discovering the relevant ones becomes more challenging in a mobile environment. The challenges include mobile devices constraints and web service descriptions itself. The issues can be considered from the aspect of mobile device’s performance, diversity of available MWS specifications and lack of enriched MWS descriptions. In order to address these issues, this paper presents an enhancement of semantic-based MWS discovery framework for discovering the most relevant MWS that takes into consideration of Non-Functional Properties (NFPs) in web service descriptions. In our work, the matchmaking algorithm with enhanced similarity measure is presented. Semantic MWS profiles are annotated semantically as a WSMO-Lite profile with a REST-based architecture. The experimental validation and statistical analysis demonstrates that the proposed framework can effectively discover relevant MWS according to the various user requirements. It can be concluded that using the proposed framework, there is a significant improvement in the effectiveness of semantic-based discovery for MWS in mobile computing environments.

SKK Migas plans to apply end-to-end security based on Web Services Security (WS-Security) for Sistem Operasi Terpadu (SOT). However, there are no prototype or simulation results that can support the plan that has already been communicated to many parties. This paper proposes an experiment that performs PRODML data transfer using WS-Security by altering the WSDL to include encryption and digital signature. The experiment utilizes SoapUI, and successfully loaded PRODML WSDL that had been altered with WSP-Policy based on X.509 to transfer a SOAP message.
