RSS-Ratio for enhancing performance of RSS-based applications [PDF]

2013 Proceedings IEEE INFOCOM, 2013
RSS (Received Signal Strength) has been widely utilized in wireless applications. It is, however, susceptible to environmental unknowns from both temporal and spatial domains. As a result, the fluctuation of RSS may degrade performance of RSS based applications.
