The Node localization problem in the mobile sensor network gains much attention. Recently, parametric point selection adopted from the Loop division has produced great positioning accuracy in conventional settings. However, a state of the art solution suffers significantly when used in mobile-based network distinguish by a high degree of radio signal irregularity. Therefore, a novel localization algorithm is required to address these challenges. We have proposed a new localization scheme by deploying sensor motivated by frugality. The distance is computed by received signal strength (RSSI) in which localization is measured as a fuzzy multilateration scheme with the help of mobile anchor deployment. RSSI and the signal power is used as an input in a fuzification. The fuzzy toolbox of Matlab is used in the entire simulation process and compared with the state-of-the-art techniques. The simulation results demonstrate an overall improvement of 60 to 70 percent in the presence of high signal irregularity.
