In large sensor networks nodes must self-configure their
communication, location, and other characteristics. GPS
and similar systems determine location today, but they require
substantial infrastructure in the environment or on
sensor nodes to locate nodes in a physical coordinate system.
For many applications, logical location — the relationship
of nodes with each other and their environment —
can be more important than physical location. For example,
distance along a road and presence of intersections
may be more relevant than Euclidean coordinates for applications
that track or guide drivers. In this paper we
present a novel algorithm, deployment order, for logical location
determination. Deployment order exploits node deployment
patterns and simple user interactions to define
logical topologies in a completely distributed manner. With
minimal user interaction it can establish arbitrarily complex
logical topologies. We illustrate the algorithm through
the "follow-me" application, which is an easy-to-deploy
sensornet guidance system suitable for use in office buildings
as well as inhospitable environments (underground, in
damaged buildings, etc.). Finally, we demonstrate how the
addition of landmarks allows the conversion from logical
locations to approximate physical locations.
