Introduction | Motivation
Requirements from participants of distributed and collaborative resource sharing.
resource requester
resource requester’s organization
resource provider
Introduction | Motivation
Resource requester: performance& functionality requirements (user-interactive computational steering)
Resource requester’s organization: agile & reliable collaboration formation & dissolve
Resource provider: finance support & improved utility
• How to form & dissolve a distributed resource sharing collaboration in an agile and lightweight manner?
• How to fulfill resource requesters’ QoS requirements?
• How to form & dissolve a distributed resource sharing collaboration in a reliable manner?
Introduction | Main questions
Negotiation protocols based on Virtual Organization, include following features:
• No communication between user’s organization and provider
• Symmetric• Not based on e-commerce regulation

Negotiation protocol states and state transition:
Results | Protocol
• asymmetric three types participants with different requirements
and responsibility to avoid denial of service for provider
• based on European Union Electronic Commerce Directive accept acknowledgement from resource requester
• re-negotiation supported can support interactive computational steering
