Received signal strength indication‐based localisation method with unknown path‐loss exponent for HVDC electric field measurement

Changes in received signals with a WLAN signal strength - based indoor localisation system

Range-free sensor localisation with ring overlapping based on comparison of received signal strength indicator

Sensor localization has become an essential requirement for many applications over wireless sensor networks. Radio irregularity and stringent constraints on hardware cost and battery power, however, make localization very challenging. Range-based localization depends on special-purpose hardware for direct measurement of the distance to reference points. Range-free localization, in contrast, doe...

Emitter localization using received-strength-signal data

This paper considers a scenario in which signals from an emitter at an unknown location are received at a number of different collinear locations. The receiver can determine the received signal strength, but no other parameters of the signal. Postulating a log-normal transmission model with a constant but unknown path loss exponent and, also, an unknown transmit power and known noise variance, ...

Maritime Management Using Received Signal Strength Indicator

For location finding through Wireless Sensor Networks (WSNs), the RSSI is regularly assumed to have a linear signal strength by the whole of the logarithm of the communication distance. However, this is not true in certain cases because there are uncertainties in RSSI readings to obstacles, receiver interferences etc. In this complimentary, we specifically ask for the hand of a new RSSI-based c...

Geometric Algorithm for Received Signal Strength Based Mobile Positioning

Mobile positioning is one of the fastest growing areas for the development of new technologies, services and applications. This paper describes a simple and efficient geometric algorithm using received signal strength measurements extracted from at least three base stations. This method is compared with standard Least Squares method. The simulation results show, that geometric algorithm gives m...
