RTI is a form of DFPL that utilizes the RSS values from a collection of wireless transceivers to produce an image in order to localize a subject within a WSN. Radio Mapping is another form of DFPL that can utilize the same RSS values from a WSN to localize a subject by comparing recent values to a set of calibration data. RTI and Radio Mapping have never been directly compared to one another as a means of localization within a WSN. The goal of this research is to compare these approaches in a side by side manner. A real world WSN was constructed and both RTI and Radio Mapping methodologies were applied to identical data sets with the results compared and discussed. Initial results show that both methodologies have inherent advantages and disadvantages respective to one another Radio Mapping performs significantly better in WSNs with a low number of transceivers, while RTI has significantly more simple calibration procedures.
