Abstract

Location support systems typically tradeoff positional accuracy, uncertainty, and latency in providing location information for ease of configuration, lower hardware costs, energy-efficiency, scalability or preserving user privacy. In this paper, we explore these tradeoffs by discussing the design space of location support systems and their impact on applications. Applications informed of these tradeoffs can adapt to them and substantially improve their performance. Location models and abstractions should therefore be quality expressive \emphi.e., provide an explicit representation of parameters such as accuracy, timeliness, energy cost
