RSS Self-calibration Protocol for WSN Localization

Abstract

In wireless sensor network (WSN) localization system, received signal strength (RSS) is one of the simplest ranging methods. However, in real situation, a RSS is affected by some errors which are caused by multi-path channel and dynamic environment. In this paper, we propose RSS self-calibration protocol to attack the errors. The RSS self-calibration protocol can adopt the calibration parameters according to environment as time goes by
