- •
We have defined and implemented a support for multidimensional range query in distributed systems.
- •
We exploited space filling curves to support the multi dimensionality.
- •
The proposal is based on the definition of a distributed aggregation tree.
- •
We investigated several aggregation techniques.
- •
The paper includes an extensive experimental analysis of the system and a comparison with a state of art proposal.
