Research of Grid Resource Discovery Method Based on Adjacency List and Ant Colony Algorithm

Grid is commonly considered as next generation network. Resource discovery is the key requirements in large heterogeneous grid environments, and an effective and efficient resource discovery mechanism is crucial. Base on centering resource discovery and distributed resource discovery methods, a hierarchical resource discovery method is proposed. Agent technology is used in every layer. Resource adjacency list as a kind of centering resource discovery method is used in the supernode of every VO. But in the middle of the supernodes of P2P layer, we use ant colony algorithm as distributed resource discovery method.
