Ledger-based Points Transfer System in LPWAN: From Disaster Management Aspect

Abstract

Low Power Wide Area Network (LPWAN) is an Internet of things (IoT) network layer technology that has emerged in recent years for long-range and low-power communication needs in IoT. Its low-bandwidth, low-power, long-range and mass-connected IoT application features can be well applied to the points transfer system. However, the traditional centralized points transfer system faces many problems such as centralization, high computational requirement of nodes, and low robustness which are difficult to be widely used. In order to solve these problems, we propose a distributed ledger-based points transfer system in LPWAN and analyze the system robustness from the disaster management aspect. The simulation results show that our proposed system can still have strong robustness under extreme disaster situations and ensure the safe and efficient operation of the whole system.
