Supply chain management requires regular updates of the location of assets, which can be enabled by low power wide area networks, such as Sigfox. While it is useful to localize a device simply by its communication signals, this is very difficult to do wit... see more

Forest fires are a fatal threat to environmental degradation. Wireless sensor networks (WSNs) are regarded as a promising candidate for forest fire monitoring and detection since they enable real-time monitoring and early detection of fire threats in an e... see more

The teaching and learning process on campus is always supervised by paying attention to attendance. Some campuses use this attendance as a condition for taking the exam. However, the attendance system is still manual, which is by using a signature on the ... see more

Large-scale Wi-Fi networks have encountered several critical issues of access point (AP) management such as manual configuration, channel interference, and unbalanced loads, which should be carefully addressed to ensure efficient system performance. Since... see more

To standardize network load and increase throughput, a new scheme is proposed to analyze the routing of wireless sensor networks (WSNs). First, the WSN model was established based on field theory with vectors and operators to analyze the transfer process ... see more

Among the treatment processes in water networks—of increasing importance in recent decades due to the progressive deterioration of water quality—filtration still represents a major solution. The present work focuses in particular on the filtration of drin... see more

Wireless Body Area Networks (WBANs) play an important role in healthcare system by enabling medical experts to guide patients without measuring face-to-face. The unauthorized access of medical data from WBAN controller as well as the unreliable data commu... see more

The requirement for radio spectrum has been increasing and this has resulted in the materialization of wireless applications with enhanced features and higher data rate. The spectrum is scant, and the current radio spectrum regulation is making its use in... see more

In node localization algorithm in Wireless Sensor Networks (WSNs), the least square method is affected by the measurement error, which leads to position error of the unknown node. In order to solve the problem that the error is too high, we propose a nove... see more
