“…Finally, we introduce a negotiation stage at the beginning of Web Service interaction between Web Service and clients to set up the streaming channel and agree on the message representation. As empirical results shows in Ref [7], the HHFR architecture outperforms conventional Web Service architecture when the client application is running on less powerful mobile device, and the client and the Web Service exchange information in a session (i.e. exchanging similar messages in series ).…”

“…Whether or not it is self-contained (maintaining self-descriptive characteristics of XML), there has been a lot of studies and proposals [5] [7][14] [15]. First, Paul Sandoz and his team at Sun Microsystem proposed Fast Infoset specification to W3C workshop on Binary Interchange of XML information Item as an XML alternative to provide faster and more efficient Web Services in restricted computing environments.…”

Web Services allow a user to integrate applications from different platforms and languages. Since mobile applications often run on heterogeneous platforms and conditions, Web Service becomes a popular solution for integrating with server applications. However, because of its verbosity, XML based SOAP messaging gives the possible overhead to the less powerful mobile devices. Based on the mobile client's behavior that it usually exchanges messages with Web Service continuously in a session, we design the Handheld Flexible Representation architecture. Our proposed architecture consists of three main components: optimizing message representation by using a data format language (Simple_DFDL), streaming communication channel to reduce latency and the Context-store to store context information of a session as well as redundant parts of the messages. In this paper, we focus on the Context-store and describe the architecture with the Context-store for improving the performance of mobile Web Service messaging. We verify our approach by conducting various evaluations and investigate the performance and scalability of the proposed architecture. The empirical results show that we save 40% of transit time between a client and a service by reducing the message size. In contrast to solutions for a single problem such as the compression or binarization, our architecture addresses the problem at a system level. Thus, by using the Context-store, we expect reliable recovery from the fault condition and enhancing interoperability as well as improving the messaging performance.

Architectures for Mobile Web Services [7] aim at providing alternative representations other than XML-based SOAP and fast communication transport options for mobile Web Services [8,2]. The approach presented in [9] uses aspect oriented programming to facilitate the access to Services from mobile devices.…”

The wide-spread adoption of powerful mobile devices allows for the design of workflows while on the move. In this paper, we leverage established SOA principles towards mobility in design and execution. For this purpose, we introduce a lightweight Service workflow model that is tailored for the needs of ad-hoc creation and mobility. We show how sensor data from mobile devices can be included during the design of Service workflows and we address crowd sourcing aspects for the deployment and execution of Service workflows. We present a proof of concept prototype application that supports the creation of Service workflows on mobile devices.

“…The use of Web services introduces, however, additional overheads in communications as a trade-off for the increase in flexibility they provide. In particular, due to the usage of XML, not only requests and replies are larger when compared to traditional Web interactions [5] but also the need for parsing the XML code in the requests adds additional server overhead.…”

Abstract.Computational science studies often rely on the availability of large datasets through the Web. Web services (WS) provide a convenient way for making those datasets available, since they rely on a standard and widely available technology. However, there are many ways to devise a Web service interface for a given dataset, and the resulting interfaces vary in their properties related to cohesion, distribution, flexibility and communication overhead, among other parameters. This paper explores these attributes and provides some directions on how they can be measured. Concretely, a well-known cohesion metric is explored as a way to characterize the possible kinds of Web service interface designs. This is discussed for a concrete distributed context of serviceoriented architectures.
