Abstract

Wireless Local Area Network Signal Strength Measurement for Sensor Localization without New Anchors

Highlights

  • The sensor network, which is used in outdoor and indoor environments, is one of the fundamental components in many Internet of Things (IoT) systems

  • We presented a sensor localization system that eliminates the deployment of new anchors

  • The key idea is to utilize the wireless local area network (WLAN) access points (APs) already installed in the environment as anchors

Summary

Introduction

The sensor network, which is used in outdoor and indoor environments, is one of the fundamental components in many Internet of Things (IoT) systems. In many IoT systems, sensor localization is a mandatory function because a sensor network is used for physical sensing. The location of sensor nodes is either generally estimated using the global positioning system (GPS) or manually measured. While building a large-scale indoor sensor network in which the GPS is unavailable, we need to measure the location of a large number of sensors. Home energy management, and building energy management systems are typical examples of large-scale indoor sensor networks.
