Long-range (LoRa) technology is most widely used for enabling low-power wide area
networks (WANs) on unlicensed frequency bands. Despite its modest data rates, it provides …

The vast demand for diverse applications raises new networking challenges, which have
encouraged the development of a new paradigm of Internet of Things (IoT), eg, LoRa. LoRa …

Abstract Long Range (LoRa) and Long Range Wide Area Network (LoRaWAN) are
emerging technologies essential in connecting and managing a wide range of devices in …

Soil moisture sensing is one of the most important components in smart agriculture. It plays a
critical role in increasing crop yields and reducing water waste. However, existing …

LoRaWAN forms a one-hop star topology where LoRa nodes send data via one-hop uplink
transmission to a LoRa gateway. If the LoRa gateway can be jammed by attackers, it may …

The growth of the Internet of Things (IoT) continues to be rapid, making it an essential part of
information technology. As a result, IoT devices must be able to handle data collection …

Wireless sensing is capable of capturing rich information of human target without requiring
sensors attached to the target. Although promising, two critical issues still exist, ie,(i) limited …

In orchards, tree-level localization of robots is critical for smart agriculture applications like
precision disease management and targeted nutrient dispensing. However, prior solutions …

Both our experiments and previous studies show that LoRa links vary dynamically, which
makes data transmission unreliable and consumes much energy of sensor nodes by …

This paper presents our design and implementation of a fast and accurate data aggregation
strategy for LoRa networks named One-shot. To facilitate data aggregation, One-shot …
