Analysis of Multiple-Bound Signals Towards Localization: A Theoretical Approach
In presence of obstacles, localization is a real challenge since multi-path effect takes place due to reflections and/or scattering of signals. There are works in the literature which discard multiple-bound signals received by sensors using statistical methods and then localize sensors using remaining signals. In literature, to the best of our knowledge, there is no deterministic way to know the number of reflections/bounds of a particular signal, so researchers have to rely on statistical methods for localization. In this paper, we analyze multiple-bound signals based on the information gathered by different ranging techniques viz. AOA, TOA, RSSI and make use of a multiple-bound signal where number of reflections are not known, to localize sensor deterministically.
