Deterministic boundary recongnition and topology extraction for large sensor networks

05361.FeketeSandor.Paper.563.pdf (0.6 MB)


We present a new framework for the crucial challenge of
self-organization of a large sensor network. The basic scenario can
be described as follows: Given a large swarm of immobile sensor
nodes that have been scattered in a polygonal region, such as a
street network. Nodes have no knowledge of size or shape of the
environment or the position of other nodes. Moreover, they have no
way of measuring coordinates, geometric distances to other nodes, or
their direction. Their only way of interacting with other nodes is
to send or to receive messages from any node that is within
communication range. The objective is to develop algorithms and
protocols that allow self-organization of the swarm into large-scale
structures that reflect the structure of the street network, setting
the stage for global routing, tracking and guiding algorithms.

Our algorithms work in two stages: boundary recognition and topology
extraction. All steps are strictly deterministic, yield fast
distributed algorithms, and make no assumption on the distribution
of nodes in the environment, other than sufficient density.
