Abstract
Location-based services are one of the demanding applications on mobile
devices that account for significant battery usage. In this paper,
we evaluate the potential average savings over using approaches such
as GPS for localization that can be achieved by (i) using local low-energy
mobile node cooperation and/or (ii) additional local infrastructure
(fixed) beacon nodes that broadcast their position. Using a random
walk simulation approach, we find that significant savings could
be attainable; we determine above 20% for 50 nodes in a 100x100 area
in the presence of beacons and 18% without. We additionally note
that the simulated nodes are able to determine their location fairly
accurately within the simulated area. We finally observe that random
background refreshes (such as those triggered by other applications)
have only little impact on the potential for savings.
