Swapped Huffman tree coding application for low-power wide-area network (LPWAN)

2016 International Conference on Smart Green Technology in Electrical and Information Systems (ICSGTEIS), 2016
Data compression and encryption play key role in the modern wireless communication technologies, especially, in internet of things (IoT). Main problems with successful implementation of IoT are; the use of low power long range devices and the requirement of managing huge amount of data; mainly, compression and security of the data transfer.

Modeling and Online Adaptation of ALOHA for Low-Power Wide-Area Networks (LPWANs)

IEEE Internet of Things Journal, 2021
Unslotted ALOHA protocol has been adopted as a channel access mechanism in commercial low-power wide-area networks (LPWANs), such as Sigfox and long-range (LoRa) alliance. This work examines the throughput and random access (RA) delay distribution of unslotted ALOHA systems by considering exponential random backoff (ERB) or uniform random backoff (URB)

Reliable Data Transmission using Low Power Wide Area Networks (LPWAN) for Agricultural Applications

Proceedings of the 16th International Conference on Availability, Reliability and Security, 2021
Reliable IT-based communication in agriculture is becoming increasingly important for regular operations. For example, if a farmer is in the field during a network outage, such as a failure of the mobile network, an alternative communication channel is needed to continue to connect to IT components and required data. With increasing digitalization, Low

A 923 MHz Steerable Antenna for Low Power Wide Area Network (LPWAN)

2020 IEEE International Conference on Communication, Networks and Satellite (Comnetsat), 2020
This study aims to support the communication network in the LoRa technology application in supporting the application of the IoT system. In Indonesia, LoRa technology is included in the communication technology based on low power wide area network (LPWAN) non-cellular by utilizing the unlicensed ISM band of 915 MHz. Generally, LoRa technology is widely

Wireless Power Transfer for LoRa Low-Power wide-area Networks (LPWANs)

2019 Southern African Universities Power Engineering Conference/Robotics and Mechatronics/Pattern Recognition Association of South Africa (SAUPEC/RobMech/PRASA), 2019
LPWANs are emerging to provide solutions for covering very low-power Internet of Things devices and applications which may be distributed over large geographical areas. LPWANs generally consume very low power thus their batteries can last for a very long time.

Low-Power Wide Area Networks (LPWAN) for Communications of Mobile Sensor Data

Proceedings of the 2nd ACM/EIGSCC Symposium on Smart Cities and Communities, 2019
There are multiple options for communication of data to and from mobile sensors. For tracking systems, Global Navigation Satellite System (GNSS) is often used for localization and mobile-phone technologies are used for transmission of data. Low-power wide area networks (LPWAN) is a newer option for sensor networks including mobile sensors. We developed
