Internet of Things, IoT, is a promising methodology that has
been increasing over the last years. It can be used to allow the connection
and exchange data with other devices and systems over the Internet.
One of the IoT connection protocols is the LoRaWAN, which has several
advantages but has a low bandwidth and limited data transfer. There is
a necessity of optimising the data transfer between devices. Some sensors
have a 10 or 12 bits resolution, while LoRaWAN owns 8 bits or multiples
slots of transmission remaining unused bits. This paper addresses
a communication optimisation for wireless sensors resorting to encoding
and decoding procedures. This approach is applied and validated on the
real scenario of a wildfire detection system.
