This study examines how an airborne device can intercept underwater acoustic signals exchanged between submerged nodes. It challenges the conventional belief that acoustic communications under the water are safe against eavesdropping since acoustics do ...

This paper investigates how an airborne node can eavesdrop on the underwater acoustic communication between submerged nodes. Conventionally, such eavesdropping has been assumed impossible as acoustic signals do not cross the water-air boundary. Here, we ...

As a fundamental concept used in human gerontology, frailty refers to the gradual decline in physiological function with aging and the resulting vulnerability to adverse health outcomes. Assessment of frailty and using this for healthcare and resource ...

Farmers grapple with the task of feeding a growing population amidst climate-induced strains on farmland, water, and energy resources. While embedded sensors present advantages over drones and satellites in precision agriculture by providing high-...

Emerging wireless IoT applications increasingly venture beyond over-the-air communication, such as deep-tissue networking for medical sensors, air-water communication for oceanography, and soil sensing for agriculture. These applications face the ...

In our daily life, people often spend time to find their forgotten or misplace items for indoor. As a result, they often lead to frustration and abandonment of the finding due to various factors. Therefore, this paper is to develop system and propose an ...

Traditional body temperature monitoring technology has some problems, such as inaccurate manual reading, unable to monitor continuously for a long time, and difficult data storage and analysis. To solve these problems, this paper designs an application ...

Point cloud data gathered through wireless sensors has garnered increasing attention for its critical applications, including automotive radars, security systems, and notably, gesture recognition. It provides a non-intrusive and robust approach ...

To realize the grand vision of automated driving in smart vehicle cyber-physical systems (CPS), one important task is to support the merging of connected automated vehicles (CAVs) from a metered-ramp to highway. Certain safety rules must be guaranteed. ...

With the advancement of the Internet of Things (IoT), many devices will be connected to the Internet, enabling digital twin and smart home applications. However, currently, these IoT devices are operating at lower frequency bands of the wireless ...

As the number of wireless end and edge devices increases, so does the volume of data to be monitored in view of predicting or detecting malfunctions. Furthermore, as the networks become more complex, the more context can be provided around a certain ...

Obtaining hands-on experience with wireless communication can be challenging due to the limited configurability of most commercial off-the-shelf transceivers. We present a low-cost and open-source educational platform designed to help students ...

Sub-6GHz and mmWave complement each other in the next generation of wireless communications for wide coverage and high capacity. However, there is still a gap between current network technology and seamless connection in indoor environments due to the ...

Fully autonomous driving applications rely on a complete knowledge of their operational environment to ensure safety while maintaining efficient driving. However, in scenarios with close visual restrictions, such as urban traffic, the lack of sensor ...

Continuous monitoring of human vital signs using non-contact mmWave radars is attractive due to their ability to penetrate garments and operate under different lighting conditions. Unfortunately, most prior research requires subjects to stay at a fixed ...

Current LoRa networks including those following the LoRaWAN specification use the primitive ALOHA mechanism for media access control due to LoRa’s lack of carrier sense capability. From our extensive measurements, the channel activity detection feature ...

DoS, GH, Sybil, Masquerading, Spoofing, Man in the Middle, etc. constantly attack IoT networks. Internal or external attacks reduce end-to-end delay, throughput, energy use, and other metrics. To counter these attacks, researchers have proposed a number ...

In the last decade, many studies have significantly pushed the limits of wireless device-free human sensing (WDHS) technology and facilitated various applications, ranging from activity identification to vital sign monitoring. This survey presents a novel ...

Long-range radio communication is preferred in many IoT deployments, as it avoids the complexity of multi-hop wireless networks. LoRa is a popular, energy-efficient wireless modulation but its networking substrate LoRaWAN introduces severe limitations to ...

Reconfigurable Intelligent Surfaces (RIS) constitute a promising technology that could fulfill the extreme performance and capacity needs of the upcoming 6G wireless networks, by offering software-defined control over wireless propagation phenomena. ...
