LECast: A Low-Energy-Consumption Broadcast Protocol for UAV Blockchain Networks

With the continuous development of communication technology, drones are playing an important role in many fields, such as power transmission line inspection and agricultural pesticide spraying. In order to protect data privacy security drones, experts considering blockchain its enabling technology. However, due their small size limited storage, cannot support energy-intensive applications. addition, future 6G communications need implement key performance indicator, namely extremely low-power (ELPCs). As a consequence, research into green is becoming more popular. The broadcast one most parts because it entails flooding there lot unnecessary processes. Therefore, make suitable for ELPC requirements unmanned aerial vehicle (UAV) networks, we took improvement candidate designed LECast, low-energy-consumption protocol. LECast first analyzes energy consumption model between two constructs shortest-path tree (SPB Tree) UAV networks minimize consumption. Meanwhile, sending drone address receiving convenient way, proposed extended Huffman coding (EHC) scheme name drones. Furthermore, other issues with reliability security. When channel fails, subsequent smoothly receive transaction or block data. result, introduced multichannel splitting (MTSD); that is, divided segments transmitted parallel multiple times over channels. Finally, through analysis simulation terms consumption, latency, throughput, reliability, security, coverage rate, advantages were confirmed, which could meet ELPCs be well applied networks.
