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

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. In this work, to cope with these issues, we have applied swapped Huffman tree (SHT) coding to a low power wide-area network (LPWAN) for realizing its benefits. The applied SHT coding compresses and encodes the data at the same time which is clearly shown in this work with the help of examples. Performance evaluation is shown at the end of the paper.
