An Emergency Communication System Based on UAV-assisted Self-Organizing Network

摘要

Emergency Communication System (ECS) becomes more and more important for certain emergency situations such as the affected mountainous areas, temporary battlefield, or filed of fire. Self-organizing network is proverbially adopted by ECS due to its flexible and robust architecture. However, the moving range and mode of mobile node in self-organizing network, especially mobile gateway, constrain the coverage and adaptability of self-organizing network in ECS. In this paper, we design an ECS based on UAV-assisted self-organizing network, which helps nodes on the ground form a self-organizing network automatically. In addition, the system adopts UAV as strong relay nodes to form relay network in the air. We also add some humanized functions in the system to adapt to the needs of different environment, which includes positioning and messages pushing service. The proposed ECS can be easily deployed in the emergency environment and owes high communication efficiency.
