Agent-based virtual organisations for the Grid

The ability to create reliable, scalable virtual organisations (VOs) on demand in a dynamic, open and competitive environment is one of the challenges that underlie Grid computing. In response, in the CONOISE-G project, we are developing an infrastructure to support robust and resilient virtual organisation formation and operation. Specifically, CONOISE-G provides mechanisms to assure effective operation of agent-based VOs in the face of disruptive and potentially malicious entities in dynamic, open and competitive environments. In this paper, we describe the CONOISE-G system, outline its use in VO formation and perturbation, and review current work on dealing with unreliable information sources

Supporting QoS monitoring in virtual organisations

There are methods proposed for managing various aspects of quality of service (QoS) in service oriented computing environments, but existing effort tends to adopt a provider-centric perspective, aiming largely at optimising and guaranteeing QoS for service delivery. In this paper, we consider QoS monitoring from a service user’s perspective. We describe an approach in which monitoring requirements are expressed as queries in a simple language and are processed against continuously arriving QoS data stream

Supporting Formation and Operation of Virtual Organisations in a Grid Environment

The ability to create reliable and scalable virtual organisations (VOs) on demand in a dynamic, open and competitive environment is one of the challenges that underlie the Grid concept and research. In this paper, we describe the agent-based mechanisms that we are currently developing within the CONOISE and CONOISE-G projects for supporting VO formation and operation

Monitoring, Policing and Trust for Grid-Based Virtual Organisations

A key challenge in Grid Computing is the ability to create reliable and scalable virtual organisations (VOs) which operate in an open, dynamic and competitive environment.

Delivering Services by Building and Running Virtual Organisations

In our view, customers in the future are likely to obtain their services from coalitions of service providers. These coalitions can be described as virtual organisations (VOs); they are group of service providers that form relationships to service customers’ demands on an ad-hoc basis. For a VO to be effective, it must be reliable and scalable, and realistically, it must be created and maintained in a dynamic, open and competitive environment. The CONOISE-G project has focused on resolving the technology challenges that emerged from these requirements. Specifically, CONOISE-G provides mechanisms to assure effective operation of VOs in the face of failure, unexpected events and changing requirements in dynamic, open and competitive environment. In this paper, we describe the CONOISE-G system; motivated by a scenario based on mobile service provision; outline its use in the context of VO formation and perturbation and review current efforts to progress the work to deal with unreliable information sources.
