Private Blockchain-Based Platform for Cool Box Truck Based on LoRa Communication Protocol

The Internet of Things utilizes software, embedded system, sensor, and network connectivity to control and monitor business processes such as supply chains. One of the implementations of IoT is LoRa (Long Range) which enables data transactions in long-range without using radio frequency. Currently, a combination of IoT and blockchain is able to increase the security level of IoT applications. Implementation of IoT in the supply chain has been done in several research by implementing blockchain and LoRa. Approximately 6.43% of the Gross Domestic Product (GDP) is attributed to logistics, with cold and hot logistics constituting around 11%. Among these, cold chain logistics, a specialized form, accounts for 9.7% of tonnage. Cold chain logistics, characterized by comprehensive temperature control, is a sophisticated system closely intertwined with advanced technology. Despite its complexity, there are still technological drawbacks leading to significant material losses on an annual basis. In this research, to overcome that problem, we proposed Blockchain-Based Monitoring System on Cool Box Trucks using LoRa. The proposed system implemented LoRa for data communication and Blockchain as decentralized databases. We simulated the LoRa environment by using FLoRa framework to obtain the optimal parameters such as Transmission Power (TP), Packet Delivery Ratio (PDR), and Spread Factor (SF) that used in TTGO T-Beam V1.
