A P2P approach for membership management and resource discovery in grids

As deployed grids increase from tens to thousands of nodes, peer-to-peer (P2P) techniques and protocols can be used to implement scalable services and application in grids. This paper proposes a P2P approach for handling two key services in grid environments: membership management and resource discovery. The membership management service exploits the use of "contact nodes", i.e. of nodes elected within virtual organizations to facilitate the assignment of neighbours and the construction of interconnections between grid nodes. The resource discovery service uses these interconnections to give grid nodes the opportunity to explore the grid and discover available resources. The paper analyzes the performance of the resource discovery service on grid networks with different sizes.
