There are many resources and services in grid environment which may be distributed geographically. So, resource discovery methods with lower update and discovery costs are of vital significance. The centralized methods have the advantage of improved management of nodes, but in a grid with large number of nodes and resources, a bottleneck is caused in the server, which reduces the system efficacy significantly. Decentralized methods proposed till now are not able to discover the required resources of the users and update their environment without any additional traffic and referral to unnecessary nodes.
