RSSI Based Improved Weighted Centroid Localization Method Using Indirect Transmission and Error Estimation

Abstract

The importance of location on a wireless sensor network cannot be overstated. There are two types of localization procedures now in use: range-free and range-based localization WSN deployment, on the other hand, is fraught with challenges. Localizing a node position is one of the issues. We used range-based location identification methods in this study, with the received signal strength indication as to the primary factor and transmission type, Direct or Indirect as the secondary element. We are using adaptive routing protocol to categorize direct and indirect transmission, weighted centroid method(WCM) for computations and Indirect transmission type calculation is based on average sequence gap values, mathematical formulations, and final error estimation is calculated.
