The Distance Measurement by Using RSSI of Wireless Sensor Network

Indoor Localization System using RSSI Measurement in Wireless Sensor Network Based on ZigBee Standard

This paper presents the studies and experiments of indoor object localization system using wireless sensor network (IEEE 802.15.4). The system is defined upon the analysis of the models of maximum likelihood estimation and received-signal-strength indicator (RSSI) by a novel method for localizing a stationary object in an indoor office environment. The proposed method utilizes the RSSI of radio...

Indoor Localization System using RSSI Measurement of Wireless Sensor Network based on ZigBee Standard

To verify the validity of our previously reported autonomous indoor localization system in an actual environment, we implemented it in a wireless sensor network based on the ZigBee standard. The system automatically estimates the distance between sensor nodes by measuring the RSSI (received signal strength indicator) at an appropriate number of sensor nodes. Through experiments, we clarified th...

RSSI based Node Localization using Trilateration in Wireless Sensor Network

Wireless Sensor Network (WSN) is an ad-hoc network generally used to perform various monitoring tasks deployed randomly in different environments. There are various applications of WSN which require the knowledge of the location of sensor node makes the sensing data more significant. This aspect of information increases the diversity of applications. In most of the Wireless Sensor Networks wher...

RSSI-based node localization algorithm for wireless sensor network

In order to overcome the problem of low accuracy of the localization algorithm based on RSSI, an improved RSSI-based location algorithm is presented in this paper. To avoid the influence of the final positioning caused by error of a single RSSI measurement value, first, median model is used to correct each value of RSSI, then, corrected value of RSSI is used to estimate the relative size of the...
