collaborative innovation networks
Collaborative Innovation Networks
  • Knowledge economy – the new reality
    • 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
  • Examples of COINS:
      • Linux developers
      • Development of WWW in CERN
      • Wikipedia
      • Really, most innovative projects today – including business
types of coin members
Types of COIN members
  • Communicators (Interested users)
    • last tier of the COIN
    • information seekers (readers)
    • communicate new ideas outside
    • example: Linux Users
  • Creators
    • the core of the COIN
    • need to be: creative, collaborative, fair
    • example: Linux Creators
  • Collaborators
    • share common knowledge and experience
    • work together to realize, improve, test new ideas
    • example: Linux Maintainers
properties of coins
Properties of COINS
  • Swarm creativity
    • creativity seen as an emergent property of an open system
  • Social network
    • essential for finding required collaborators
  • Sharing and frequent communication
    • information is freely shared among trusted, cooperating persons
  • Virtual trust through ethical code
    • Trust is established through following an ethical code requiring recognition of other’s input, meritocracy
mteam agenda
mTeam agenda
  • Enabling the creation of applications that would use social networks and mobility to find new collaboration opportunities and tools to support collaboration
  • In other words: enable building a COIN in a nomadic environment, supporting mobility
    • a heterogenous environment: fixed/mobile
      • Supporting nomadic teams
    • needs:
      • social network
      • environment for sharing
      • trust, access control, security (in a decentralized setting)
      • resource discovery and communication primitives
mteam goals
mTeam goals
  • 3D social network:
    • expresses tacit knowledge about environment of a user (“mental map”)
    • includes: familiarity, skills/experience, trust/reputation
  • Collaboration tools:
    • a middleware for typical collaboration activities/functions
  • Handling heterogenous mobile environment and the inherent distributed/decentralized settingusing a P2P information systems infrastructure
mteam deliverables
mTeam deliverables
  • TeamCreator
    • 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.)
  • TeamEnvironment
    • 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

Distributed computing

P2P information system
  • Share the resources of individual peers
    • CPU, disk, bandwidth, information, …
basic p2p layer functions
Basic P2P layer functions
  • Routing and information search
    • it can be constrained by other requirements, such as trust
  • Publish-subscribe
    • subscribe to a topic, publish, notify
    • in ad-hoc environments, needs to be delay-tolerant
  • Multicast
    • special case of publish-subscribe
  • etc …
research issues
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.

research issues1
Research issues
  • Privacy issues (beyond the scope of mTeam’s requirements) as well as some common security issues
    • Informal collaboration between NTU Singapore & Deutsche Telekom Laboratories (Berlin)
technical issues open standards and open sources
Technical issues: Open standards and open sources …
  • Whether and how much to use SIP ?
  • How standard will interfaces like P2PP be ?
  • Open source Android SDK or some other environments for mobile devices ?
    • Politics of hardware/cellular service providers, etc.
  • UMPCs
proof of concept driver applications
Proof of concept: Driver Applications
  • Not part of the original deliverables …
    • An collaborative editing application for research papers, capable of sharing and reviewing academic literature and news, as well as finding relevant collaboration opportunities
      • Ongoing
    • 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)
status
Status
