Abstract

Improving the accuracy rate in the localisation of mobile sensor networks is challenging. Mobile localisation in mobile sensors has various applications, such as mobile robot navigation, networking taxi service for finding the nearest taxi drivers, vehicle ad hoc networks for rerouting the path during road accidents, site works, and many more. In this research work, we have adopted the experimental data from the literature by Marti et al. and performed a simulation to predict the location in three different environments, such as garden, classroom, and corridor. All three environments have been configured with 55 transmitters and four beacons, the localisation has been calculated with received signal strength (RSS), and the data uncertainties in RSS are addressed by implementing the fuzzy logic system using semi-elliptic membership function (SEMF), which has an improved accuracy rate compared to conventional controllers.
