In the last decade, bureaucratic organizational hierarchies have been increasingly replaced with flatter organizational forms, bringing together people from different disciplines to form project teams within and between organizations. Distributed project teams often are self‐configuring networks of mobile and “fixed” people, devices, and applications. They are the natural next step in the evolution of distributed computing, after client‐server, web‐based, and peer‐to‐peer computing. Seeks to show that a newly emerging requirement is to facilitate not just mobility of content (i.e. to support a multitude of devices and connectivity modes) to project members, but also mobility of context (i.e. to provide traceable and continuous support of dynamic relationships between people, artifacts, and business processes).

The contribution of this paper is to present the design goals, the architecture, and implementation of a system aiming at supporting internet‐enabled workflow and groupware for project teams, enabling traceable and continuous support of associations (relationships) between people, artifacts, and business processes.

The findings indicate that building internet‐enabled workflow and groupware systems is valuable for virtual teamwork, since they provide a foundation for context‐aware and process‐aware information systems.

This article outlines some foundations of process‐aware collaborative work. Provides an analysis of current workflow and groupware shortcomings in respect of virtual teamwork, outlines the design goals, architecture and an implementation of a system aiming at supporting virtual teams on the internet.

This survey aims to study and analyze current techniques and methods for context‐aware web service systems, to discuss future trends and propose further steps on making web services systems context‐aware.

The paper analyzes and compares existing context‐aware web service‐based systems based on techniques they support, such as context information modeling, context sensing, distribution, security and privacy, and adaptation techniques. Existing systems are also examined in terms of application domains, system type, mobility support, multi‐organization support and level of web services implementation.

Supporting context‐aware web service‐based systems is increasing. It is hard to find a truly context‐aware web service‐based system that is interoperable and secure, and operates on multi‐organizational environments. Various issues, such as distributed context management, context‐aware service modeling and engineering, context reasoning and quality of context, security and privacy issues have not been well addressed.

The number of systems analyzed is limited. Furthermore, the survey is based on published papers. Therefore, up‐to‐date information and development might not be taken into account.

Existing surveys do not focus on context‐awareness techniques for web services. This paper helps to understand the state of the art in context‐aware techniques for web services that can be employed in the future of services which is built around, amongst others, mobile devices, web services, and pervasive environments.

The purpose of this paper is to examine how cloud‐based information systems and services can support emerging and future requirements for sustainability governance of facilities.

The authors present basic elements of cloud‐based sustainability governance platforms, conduct a survey of existing industrial platforms and research works, discuss distinguishable and common characteristics of cloud computing platforms for sustainability governance, and give views on future research.

Cloud computing emerges as a potential candidate for supporting sustainability governance. However, several techniques must be provided in order to support multiple stakeholders, complex analysis and compliance processes.

The number of industrial platforms and research works in the survey is limited, as is information about industrial platforms. Furthermore, industrial platforms are continuously updated, thus some information might be outdated.

There exists no survey for understanding how cloud computing could be used for sustainability governance. The paper not only helps to understand state‐of‐the‐art in using cloud computing for sustainability governance but also discusses main components, stakeholders and requirements for cloud‐based sustainability governance platforms.

The capabilities of embedded devices such as smartphones are steadily increasing and provide the great flexibility of data access and collaboration while being mobile. From the distributed computing point of view, fundamental issues in mobile computing include heterogeneity in terms of varying device capabilities (i.e., operating systems and various hardware platforms), performance characteristics and real‐time behavior, and the ability to discover and interact with peers seamlessly. Web services are a family of XML based protocols to achieve interoperability among loosely coupled networked applications. We propose the use of Web services on embedded devices in order to solve interoperability issues in distributed mobile systems. We discuss various toolkits available for embedded devices and investigate performance characteristics of embedded Web services on smartphones. Our goal is to guide the design of Web services based applications on mobile devices, and provide estimates of performance that can be expected.
