Abstract

The collaboration of services scattered over the internet is often required in solving a complicated scientific problem or finishing a complex business process. Centralized client/server architecture used in traditional service collaboration mechanism such as workflow has exhibited many weaknesses. We adopt the concept from peer-to-peer computing and Synergetics, and introduce an innovative middleware for structured-based service collaboration, in which each service node belongs to one or more structured collaboration organizations and is allowed to join and leave (planned departure or sudden failure) freely. We also propose neighborhood-based maintenance mechanism to cope with the dynamics of collaboration organization structure in a decentralized manner.
