Abstract
Localization remains a challenging problem in
wireless sensor networks community. There are many algorithms
for localization proposed in the literature, ranging from very basic
to very complex. Among them, trilateration is one of the oldest and
simplest approach, that can be used alone, or as part of more
complex pipelines. In this paper we explore two different heuristics
that adopt trilateration as a base technique. Our heuristics use
distance information together with knowledge about the most
appropriate anchors in terms of quality. We show that by
improving trilateration with different heuristics, localization error
can be significantly reduced, while maintaining low computational
cost.
