Abstract
Effective use of computational grids requires up-to-date in-
formation about widely-distributed resources within it a
challenging problem given the scale of the grid, and the
continously changing state of the resources. We propose
non-uniform information dissemination protocols to effi-
ciently propagate information to distributed repositories,
without requiring flooding or centralized approaches. Cap-
italizing on the observation that grid resources are of more
interest to nearby users, we disseminate resource informa-
tion with a frequency and resolution inversely proportional
to the distance from the resource. Results indicate a signif-
icant reduction in the overhead compared to uniform dis-
semination to all repositories.1
