Proof-of-Location (PoL) is a lightweight security concept for Internet-of-Things (IoT)
networks, focusing on the sensor nodes as the least performant and most vulnerable parts of …

In this paper, we describe the positioning technique for camera based smartphone in an
indoor environment. The camera of smartphone detects multiple light-emitting diode (LED) …

Wireless sensor networks are a collection of sensor nodes that collaborate to sense a
specific event in a given environment. When sensors monitor a structure organized linearly …

Insecurity of human and properties in Nigeria has risen to an alarming situation and calls for
immediate attention. Kidnapping has become so rampant that these days not only the …

In this paper, we propose a hybrid LoRaWAN/GPS solution for the tracking of athletes
performing outdoor sport activities. The combination of the two technologies has the main …

The purpose of this paper is to propose an advanced fingerprint-based indoor localization
scheme for wireless sensor networks (WSN) to improve the accuracy. Many localization …

The adaptation of localization in a real-world environment can be observed by popular
commercial and non-commercial GPS applications. However, with the advent of the Internet …

The Received Signal Strength Indicator (RSSI) is a preferred metric for localization and
distance estimation among researchers. Although it is easy to use, as it is available for most …

Dans cette thèse, nous nous sommes intéressés aux réseaux urbains considérés par le
projet ANR ARESA2 qui sont principalement des réseaux de capteurs et actionneurs …

Clustering is one of the most energy-efficient methods to organize sensor nodes in Wireless
Sensor Networks (WSNs). To perform clustering, location data are usually used for …
