In wireless sensor networks (WSNs), most time synchronization protocols allow synchronizing the different nodes’clocks with the clock of a reference node called ROOT. The position of the ROOT determines the accuracy of time synchronization. Indeed, the closer the ROOT is to the other nodes in the network, better is the accuracy. In this paper, we p...

In wireless communication technology, wireless sensor networks usually need to collect and process information in very harsh environment. Therefore, accurate positioning of sensors becomes the key to wireless communication technology. In this study, Davidon–Fletcher–Powell (DFP) algorithm was combined with particle swarm optimization (PSO) to reduc...

Wireless sensor networks (WSNs) require accurate localization of sensor nodes for various applications. In this article, we propose the distance vector hop localization method (DVHLM) to address the node dislocation issue in real-time networks. The proposed method combines trilateration and Particle Swarm Optimization techniques to estimate the loc...
Nowadays, to improve animal well being in livestock farming application, a wireless video sensor network (WVSN) can be deployed to early detect injury and monitor animals. They are composed of small embedded video and camera motes that capture video frames periodically and send them to a specific node called a sink. Sending all the captured images ...
Avec des gradients de températures élevés et permanents, une aciérie est le lieu idéal pour installer des thermogénérateurs. L'électricité récupérée est stockée dans des supercapacités puis conditionnée pour alimenter un capteur sans fil communicant (une sonde lambda très énergivore et ses auxiliaires). La particularité du projet est liée à l'envir...

Published in Journal of Physics: Conference Series
To ensure the integration of wireless sensor network and broadband wireless communication network, we establish a new generation of power IoTs information communication system for smart grid, and propose a distribution automation terminal solution based on eSIM card. An adaptive access algorithm based on multi logic eSIM priority, and a WSN based p...

The intrusion detection in network traffic for crucial smart metering applications based on radio sensor networks is becoming very important in the Smart Grid area. The network’s structure for smart meters under investigation should consider important security factors. The potential of both passive and active cyber-attacks affecting the functioning...
While the ongoing fourth industrial revolution continues to be a major driver behind wireless communication technologies, some environments are so prohibitive that even state-of-the-art solutions can barely achieve ubiquitous wireless connectivity (if at all). For example, in industrial sites with large metal constructions (such as petrochemical pl...
