RSSI quantization for indoor localization services
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017Received Signal Strength Indication (RSSI) measurements are known to be noisy and to exhibit high degree of variability, yet massive sets of RSSI data are streamed and collected with the purpose of using them for localization. In this paper we determine that the full resolution of RSSI measurements is unnecessary and propose, based on an evaluation of ...

Predicting Car Collisions Using RSSI
2015 IEEE Global Communications Conference (GLOBECOM), 2014The periodic broadcast of a safety message (SM) containing vehicle position and motion data is the salient mechanism for providing drivers pre-crash alerts in Vehicle-to-Vehicle (V2V) networks. However, if SMs are compromised or contain erroneous information, drivers may be unaware of impending danger.

Improving Positioning Algorithm Based on RSSI
Wireless Personal Communications, 2019Nowadays, a large number of positioning studies based on RSSI technology mainly focused on the coordinate position by measuring the distance using the certain algorithm. The difference between calculated distance and real distance became rather lager due to the poor solution to improve the impact of environment to RSSI, and the bad repeatability ...

RSSI-Based Ranging for Pedestrian Localization
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018Pedestrians are particularly vulnerable traffic participants with a very high fatality rate. An important component of Advanced Driver Assistant Systems is the accurate localization of pedestrians and other vulnerable traffic participants using various sensors and other technologies.

Compensation of the Antenna Polarization Misalignment in the RSSI Estimation
Proceedings of the 3rd International Conference on Sensor Networks, 2014The diffusion of wireless sensor networks has allowed the development of a plethora of indoor localization algorithms based on these technologies. Also if several radio signal features have been exploited in order to estimate the position, the Received Signal Strength (RSS) is probably the most used.

RSSI-based Indoor Localization Using RSSI-with-Angle-based Localization Estimation Algorithm
International Journal of Sensor Networks and Data Communications, 2015For the scenarios of indoors localization and tracking, the solutions generally need complex infrastructure because they would require either a grid of antennas, each having a well-known position (proximity based approach), or a sophisticated algorithm that uses scene fingerprint to estimate the location or the zone of an object by matching the online ...

Study of characteristics of RSSI signal
2008 IEEE International Conference on Industrial Technology, 2008Numerous experiments are used in order to discuss the strength of received signal strength index(RSSI) signals due to changes in the environment, and the effects of time domain and frequency domain on RSSI signals has been proposed in this paper. RSSI signal's strength, in connection to the link quality, is categorized as: Good (RSSI >40), Acceptable ...

Analysis of RSSI in diverse field
International Conference on Information Communication and Embedded Systems (ICICES2014), 2014IEEE.802.15.4 based ZigBee will play an vital role in the future of different fields of wireless communication due to its long battery life and less power consumption. The RSSI of radio signals used to estimate the distance between ZigBee nodes and it does not require any hardware additionally other than simply a radio transceiver.

The Location of the WSN-Nodes Based on RSSI
2011Particular introduced the ranging theory, the correction technology and the location algorithm of the WSN’s ranging location based on the RSSI (Received Signal Strength Indication). For the problem of the nonlinear equations need to be solved in the location algorithm, this paper uses the UKF (Unscented Kalman Filter) algorithm, uses the algorithm’s ...
