Abstract
This paper presents a novel peer-to-peer
system that is particularly well suited to support context-aware
computing. The system, called GeoPeer, aims to combine the
advantages of peer-to-peer systems that implement distributed hash
tables with the suitability of geographical routing for supporting
location-constrained queries and information dissemination. GeoPeer
is comprised of two fundamental components: a Delaunay triangulation
used to build a connected lattice of nodes and a mechanism to manage
long range contacts that allows good routing performance, despite
unbalanced distribution of nodes.
