Age of Information (AoI) has become a new metric for data freshness in Unmanned Aerial Vehicle (UAV)-assisted data collection. Whereas, the UAVs are usually energy-limited. When they leave to be charged, the AoI may increase additionally. Current studies of optimizing the AoI usually consider the situation where charging facilities are sufficient, which is not true in many scenarios. For the situa...Show More
Exploiting and sharing unlicensed spectrum resources among cellular and WiFi networks is critical for the fifth-generation (5G) and beyond networks due to the severe spectrum shortage and huge traffic demands. While distributed consensus with blockchain has been considered to realize fair and efficient spectrum sharing, the existing mechanism is not adaptive to wireless network traffic with divers...Show More
In unmanned aerial vehicle (UAV) networks, the route efficiency is crucial for effective cooperation among the UAVs. However, due to the highly dynamic topology and environment of UAV networks, current routing schemes usually suffer from performance degradation. To address this issue, in this paper we propose a blockchain and deep Q-network (DQN) enabled co-evolutionary routing (BDCoER) scheme for...Show More
