Multidimensional Range Queries on Hierarchical Voronoi Overlays

Ref: CISTER-TR-160406       Publication Date: Nov 2016

Abstract:
The de nition of a support for multi-attribute range queries is mandatory for highly distributed systems. Even if several solutions have been proposed in the last decade, most of them do not meet the requirements of recent platforms, like IoT or smart cities. The paper presents an approach that builds a multidimensional Voronoi graph by exploiting the attributes of the objects published by a node. Our solution overcomes the curse of dimensionality issue a ecting Voronoi tessellations in high dimensional spaces by de ning a Voronoi hierarchy. The paper formally de nes the structure, analysis the complexity of the operations and presents experimental results.
