  This paper proposes a simple and scalable web-based model for grid resource
discovery for the Internet. The resource discovery model contains the metadata
and resource finder web services. The information of resource finder web
services is kept in the repositories that are distributed in the application
layer of Internet. The resource finder web services will be discovered by
sending queries to the repositories in a similar way as the DNS protocol. The
underlying technology for implementation of the two architectures of this model
is introduced. These architectures are: Direct and Centralized Web-Based Grid
Resource Discovery. The resource discovery time is computed after simulating
each of these models in GridSim. By performing scalability tests, we found that
when increasing the load on the grid with more users and resources, the cost of
our model in comparison to the grid resource discovery time is marginal.
