Fire is one disaster that often leads to the large amount of material losses and casualties. This is partly due to the lack of support tools provided by residential buildings. There are two kinds of systems of fire protection of buildings against disaster... see more

We propose a novel method to detect and locate a Man-in-the-Middle attack in a fixed wireless network by analyzing round-trip time and measured received signal strength from fixed access points. The proposed method was implemented as a client-side applica... 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

In this study, we design a state predictor-based output feedback controller that compensates for unavoidable time-varying network delays in networked control systems (NCSs) over Wi-Fi networks. We model time-varying network delays as timevarying input del... see more

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

Modem is a device that has the ability to connect cellphones, PCs or laptops to the internet network. The type of modem that is popular today is MiFi or Wi-Fi Modem, which is a portable modem that makes it easier for users to carry the device anywhere. Cu... see more

Many automated attendance systems have been proposed in academia. However, all of them require the attendees to consciously record their attendance. This is prone to human error as some attendees may forget to do that. It is also distractive as the record... 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
