Theoretical facts on RSSI-based geolocation
2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel, 2012We address the problem of locating a stationary emitter using the Received Signal Strength (RSS) at receivers with known locations. The Maximum Likelihood estimator for the emitter location requires the minimization of a non-convex cost function. Since this cost function exhibits numerous local minima, its global minimization is usually realized by ...

RSSI evaluation for multi-story building
2015 Internet Technologies and Applications (ITA), 2015In this paper we investigate the reliability of ray tracing simulator in predicting the indoor radio channel response through a well specified environment. The knowledge of the indoor environment geometric and martial properties led to such site specific modeling.

CORDIC implementation of RSSI localization method
2010 Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics (PrimeAsia), 2010In this paper, a computational function based on the CORDIC algorithm for location estimation is proposed. Position awareness is a desirable feature for many applications of Wireless Sensor Networks. The Received Signal Strength Indicator (RSSI) values provide a feasible way for relative position estimation.

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 ...

RSSI-based localization in cellular networks
37th Annual IEEE Conference on Local Computer Networks -- Workshops, 2012This paper presents a novel RSSI based localization scheme that employs an existing cellular network infrastructure to perform trilateration. Traditional localization schemes employ RSSI-based radial distance estimation and trilateration algorithm.

Low power RSSI outdoor localization system
2016 12th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2016This work presents a low power outdoor localization system that implements a power management technique in order to control the wakeup and sleep of the different modules in the system. Through this technique, the system achieves 6.7 µA in sleep mode.

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 Positioning Technics in Networks
2010Les informations de (geo)localisation et l'auto-organisation dans des environnements réseaux hétérogènes sont cruciales. Dans cet article nous réalisons un état de l'art des techniques de positionnement basées sur la puissance du signal reçu (RSSI), les analysons et les comparons avec des métriques globales telles que la précision et la consommation d ...
