Artificial Bee Colony-Aided UAV Deployment and Relay Communications for Geological Disasters

Geological disasters cause great threat to people's life and property. Therefore, it is necessary to take close supervise and monitoring to geological disasters to take timely measures. To address this, communication needs to be established between the emergency operation center and the monitoring equipment. Traditional communication mode obviously cannot accomplish this task which is complex and dangerous. Hence, unmanned aerial vehicle (UAV) becomes an ideal choice given its high maneuverability and strong scalability. Considering the factors of cost and security, how to deploy UAVs is a key factor. In this paper, first of all, an optimization model for both minimizing cost and maximizing security is formulated. Moreover, a K-means and depth first search aided-artificial bee colony algorithm (KDFS-ABC) is proposed. Finally, extensive simulation results demonstrate that our proposed model outperforms the sate-of-the-art works in terms of computational complexity and the cost of UAV systems.
