Collaborative Innovation Networks r Knowledge economy – the new reality m also called “Collaborative Innovation Networks” – COINS • typically these are self-organizing, open systems • source: Peter Gloor (MIT Sloan), Competitive Advantage through Collaborative Innovation Networks, Oxford University Press, 2006; www. swarmcreativity. net r Examples of COINS: • • Linux developers Development of WWW in CERN Wikipedia Really, most innovative projects today – including business m. Team @ Warsaw, 20 th May 2008

Types of COIN members r Creators m the core of the COIN m need to be: creative, collaborative, fair m example: Linux Creators r Collaborators m share common knowledge and experience m work together to realize, improve, test new ideas m example: Linux Maintainers r Communicators (Interested users) m m last tier of the COIN information seekers (readers) communicate new ideas outside example: Linux Users m. Team @ Warsaw, 20 th May 2008

Properties of COINS r Swarm creativity seen as an emergent property of an open system r Social network m essential for finding required collaborators r Sharing and frequent communication m information is freely shared among trusted, cooperating persons r Virtual trust through ethical code m Trust is established through following an ethical code requiring recognition of other’s input, meritocracy m. Team @ Warsaw, 20 th May 2008

m. Team agenda r Enabling the creation of applications that would use social networks and mobility to find new collaboration opportunities and tools to support collaboration r In other words: enable building a COIN in a nomadic environment, supporting mobility m a heterogenous environment: fixed/mobile • Supporting nomadic teams m needs: • • social network environment for sharing trust, access control, security (in a decentralized setting) resource discovery and communication primitives m. Team @ Warsaw, 20 th May 2008

m. Team goals r 3 D social network: m expresses tacit knowledge about environment of a user (“mental map”) m includes: familiarity, skills/experience, trust/reputation r Collaboration tools: m a middleware for typical collaboration activities/functions r Handling heterogenous mobile environment and the inherent distributed/decentralized setting using a P 2 P information systems infrastructure m. Team @ Warsaw, 20 th May 2008

m. Team deliverables r Team. Creator m uses the social network to recommend and buld a team to solve a problem • • build a team from a COIN form a new COIN restructure a team negotiate rules of engagement in the team (who does what, when, etc. ) r Team. Environment m uses collaboration middleware to enable a team to work on shared information • • includes a distributed versioning system gives users rich context awareness allows collaborators to communicate gathers social information required to build social network m.

Research issues The project will investigate the full-spectrum of research topics and technologies to enable nomadic collaboration or collaboration on the go, including algorithmic foundations and basic research on Networked Distributed Systems which will support upper layer functionalities and ubiquity independent of device and location, Social Networking to facilitate new collaboration opportunities and finally the Collaboration Tools themselves to carry out the tasks and manage such collaborations. m.

Research issues r Privacy issues (beyond the scope of m. Team’s requirements) as well as some common security issues m Informal collaboration between NTU Singapore & Deutsche Telekom Laboratories (Berlin) m. Team @ Warsaw, 20 th May 2008

Research issues m. Team @ Warsaw, 20 th May 2008

Technical issues: Open standards and open sources … SIP ? r How standard will interfaces like P 2 PP be ? r Open source Android SDK or some other r Whether and how much to use environments for mobile devices ? m Politics of hardware/cellular service providers, etc. r UMPCs m. Team @ Warsaw, 20 th May 2008

Proof of concept: Driver Applications r Not part of the original deliverables … m An collaborative editing application for research papers, capable of sharing and reviewing academic literature and news, as well as finding relevant collaboration opportunities • Ongoing m An application geared specifically to facilitate collaboration among environment scientists • Tentative (pending a Swiss/Singapore joint project on cyber-infrastructure for environment monitoring and modeling) m. Team @ Warsaw, 20 th May 2008

Status r Research work m Ongoing literature and technology survey on various themes • Tutorial on “SIP, IMS and P 2 P-SIP” at IFIP Networking 2008 • Book chapter (proposal accepted): Vertically Integrated Collaboration Middleware in Mobile P 2 P Environments m m Groundwork for first driver application well in progress Study of dynamics in open collaboration systems (Wikipedia) r Hiring m Poland: • One Ph. D. student and one research assistant hired m Singapore • Hiring is ongoing • One Ph.
