Addressing the challenge of swiftly establishing effective emergency communication links between ground equipment and external rescue organizations post-disaster, the system employs emergency communication vehicles to relay information from the backend rescue center to UAV base stations deployed in the air.
As illustrated in Fig. 1, a suburban emergency communication network is deployed in response to an earthquake disaster, establishing crucial communication links between the disaster zone and the external environment. UAV is used as temporary base stations.
Abstract: Reliable and flexible emergency communication is a key challenge for search and rescue in the event of disasters, especially for the case when base stations are no longer functioning. Unmanned aerial vehicle (UAV)-assisted networking is emerging as a promising method to establish emergency networks.
To address these issues, we propose a UAV-based emergency communication system with a HybridComm architecture. This architecture optimizes the UAV’s aerial position, uplink and downlink time slot ratio, and bandwidth allocation based on feedback from transmission rates and channel losses, ensuring optimal resource allocation.
Unmanned aerial vehicle (UAV)-assisted networking is emerging as a promising method to establish emergency networks. In this article, a unified framework for a UAV-assisted emergency network is established in disasters.
In this section, we rigorously evaluate the performance of the proposed post-disaster emergency communication network system based on the PPO algorithm through comprehensive simulation analyses. The focus of our simulations includes the initialization positions of UAV, the action space, and the minimum communication rate thresholds.
