Abstract Long-range module (SX1278) is a very popular chip widely used in IoT because of its low power consumption with long range (with almost 1 km in urban areas) to send data in the form of small chunk of packets based on wide area radio technology as it just broadcast the messages similar to radio transmission broadcast. It is the most popular application in almost all sectors of industry ranging from smart cities, smart agriculture, smart healthcare, and many more. But the main problem with LoRa technology is that the average packet loss while sending the data is almost 50%, i.e., there is 0.5 probability that the packet will not be received at the receiving end [1]. To increase reliability and security of the data we are sending, we have proposed a basic logic to make sending–receiving of packets more reliable using the concept of serialization of packets and securing them (using RSA algorithm).

1 Introduction By 2020, it is estimated that there will be 50 billion connected devices to be part of the Internet of things, as large as the network seems, it is less in everything, i.e., less memory, less processing power, and less bandwidth, and of course, less available energy [2]. LoRa is the emerging technology that satisfies all the above conditions. LoRa (LoRa Alliance, https://Lora-alliance.org) is one such LPWAN protocol and the subject of study for this paper. LoRa targets deployments where end-devices have limited energy (for example, battery-powered), where end-devices do not need to transmit more than a few bytes at a time [3] and where data traffic can be initiated either by the end-device (such as when the end-device is a sensor) or by an external entity wishing to communicate with the end-device (such as when the end-device is an actuator). The long-range and low-power nature of LoRa makes it an interesting candidate for smart sensing technology in civil infrastructures (such as health monitoring, smart metering, and environment monitoring), as well as in industrial applications. Different communication technologies aimed at low-power, wireless IoT communication have been proposed and deployed. As indicated above, these grossly fall within two categories: 1. Low-power local area networks with a less than 1000-m range 2. Low-power wide area networks, with a greater than 1000-m range
