Relative Localization of Wireless Sensor Nodes by Using the RSSI Data

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...

The Distance Measurement by Using RSSI of Wireless Sensor Network

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...

RSSI-based Rings Overlap Localization Algorithm in Wireless Sensor Network

This paper proposes a RSSI-based rings overlap localization algorithm of Environment Adaption(RROLA/EA) for large-scale wireless sensor network (WSN). Localization technology is one of the key technologies in most applications of wireless sensor network. Localization technology is composed of two phases: ranging phase and localization phase. RSSI-based ranging method is adopted in the ranging p...

RSSI-based Indoor Mobile Localization in Wireless Sensor Network

Abstract Location techniques play an important part in wireless sensor network. The received signal strength indicator (RSSI) based localization is a promising technique since it requires relatively low configuration and energy. The received signal strength is mainly influenced by propagation environment in wireless sensor network. So we proposed an indoor mobile location algorithm (IMLA). We f...
