A Linear Localization Algorithm for Wireless Sensor Network Based on RSSI

  • Conference paper

Part of the Communications in Computer and Information Science book series (CCIS,volume 176)

Abstract

Node localization and tracking is a highlight research in wireless sensor networks(WSN), and localization algorithm plays the most important role in improving the localization accuracy. To overcome the drawback of the low localization accuracy of conventional Least Squares(LS) with small number reference nodes, this paper proposes a linear algorithm based on received signal strength indicator (RSSI), which implements Taylor Series Expansion to linearize binary quadratic equations. With the same number reference nodes, simulation result shows, compared to conventional LS, the linear algorithm can highly enhance the localization accuracy.
