Abstract
Current mobile applications oftentimes require power-consuming localization
services. In this paper, we outline the co-localization approach,
where nodes share their location with peers, enabling a reduction
in the costs of localization when a precise location fix is desired.
While several works in this domain compare the accuracy of localization
techniques in cooperative scenarios, we focus our evaluation on the
power consumption and accuracy that can be achieved. We present a
first model and evaluation using statistics and traces derived from
two human mobility models. We find that for 15 minute intervals of
location requests, a cooperative localization approach can reduce
the costs associated with localization if half of the nodal peer
encounters are with location-sharing nodes and GPS is usable about
half the time.
