OODC: An Opportunistic and On-Demand Forwarding Mechanism for LPWA Networks

The single-hop star-of-stars topology of current Low Power Wide Area Network (LPWAN) is simple and robust but still lack of network coverage because of signal attenuation. We present a forwarding mechanism to increase the coverage and re-liability of LPWAN. Two key characteristics of our approach are on-demand and opportunistic forwarding. While most previous studies adopt […]

Proposal of Seamless Communication Method in Shadow Area Using LoRaWAN

Low-Power Wide-Area Networking (LPWAN) technology is attracting attention as a communication technology for IoT(Internet of Things) by enabling low-power and long-distance transmission. In this paper, based on Long Range (LoRa) technologies, one of representative technologies in LPWAN area, we suggest the need for multi-hop communication class to solve the communication shadow area and discuss the […]

Design and Implementation of object tracking system based on LoRa

Internet of Things(IoT) technology is an global infra that offers intellectual services combined with situation recognizing knowledge and communication between humans and objects and among objects, which has become core technology in hyper-connected society with its Cloud and big data technology. To connect objects, low range and low power communication technology was needed, therefore, LoRaWAN […]

Low-Power, Long-Range, High-Data Transmission Using Wi-Fi and LoRa

Along with the commercialization of the Internet of Things (IoT) technology, the demand for long-range, low-power and long-range, large amount of data transmission arises. However, there has been no such communication technology to satisfy the transmission. The Wi-Fi is able to send large amounts of data with its broadband technology, but because of high power […]
