A Web-based peer-to-peer architecture for collaborative nomadic working

Abstract

With the recent advances in mobile computing, distributed organizations are facing a growing need for advanced Information and Communication Technologies (ICT) that support mobile working. The ability to use information effectively anywhere and anytime has become a key business success factor: Although many Computer Supported Collaborative Work (CSCW) systems have been introduced to date, technologies and architectures that support the collaboration of nomadic workers on a wide range of mobile devices, notebooks and personal computers is still a challenge. The Mobile Teamwork Infrastructure for Organizations Networking (MOTION}' project is aiming to design a highlyjexible, open and scalable ICT architecture for mobile collaboration. In this papeq we present the mobile collaboration requirements of two MOTION industry case studies, and highlight the advantages of a Web-based peer-to-peer architecture and for nomadic working.

Formally designing Web services for mobile team collaboration

“…MOTION is a platform we designed and prototyped in the MOTION European project [5,12,24,20] where the needs of two well known organizations were addressed. The first is a manufacturer of mobile phones and the second is a producer of white goods (e.g.…”

“…independently of the behavior of other devices. The justification of this architecture can be found in [20]. We call each device in this p2p architecture a peer (or a MOTION peer).…”

“…To get a flavor of the challenges in applying formal methods to the development of web services, we redesign the MOTION [5,12,24,20](MObile Teamwork Infrastructure for Organizations Networking) platform which is a platform for mobile team collaboration that one of this paper's authors was co-architect and co-developer of. The MOTION platform is a typi-cal example of enterprise wide, open, and Internetand component-based application, hence, an interesting candidate for the application of the web service technology.…”

Towards an access control system for mobile peer-to-peer collaborative environments

“…The MOTION [8,10] (MObile Teamwork Infrastructure for Organizations Networking) service architecture that we have developed supports mobile teamwork and relies on a P2P middleware. The MOTION system has a layered architecture consisting of three layers (as depicted in Figure 1).…”

“…Section 2 investigates the requirements for authorization in mobile, P2P, and collaborative systems. Section 3 gives an overview of the MOTION [8,10] platform, a platform for mobile P2P teamworking, and presents its access control mechanism. Section 4 discusses the evaluation of the MO-TION access control system regarding advocated requirements.…”
