灾害场景下基于MADRL的信息收集无人机部署与节点能效优化
MADRL-based UAV deployment and node efficiency optimization for information collection in disaster scenarios
摘要
Abstract
In the disaster scene,the timely and reliable collection of first-hand and important information in the disaster area is the key to the early disaster warning research and rescue work.Unmanned aerial vehicle(UAV)is an efficient auxiliary tool for establishing emergency communication network within disaster zones.Through the investigation of the deployment methods of UAV in emergency scenarios in the existing research,this paper reported the problem that node energy efficiency was not considered in UAV deployment.Since the ground sensor nodes were located inside the disaster area in a hostile and extremely passive environment,the combination of disaster scenarios.Taking improving the energy efficiency of ground nodes as the opti-mization goal for the first time,based on the deep reinforcement learning method and on the basis of DDQN network model,the adaptive deployment problem of UAV for information collection in disaster scenarios was solved by defining experience playback priority,reasonably designing reward function and adopting complete decentralized training method.Simulation re-sults show that the energy efficiency of the nodes under the proposed algorithm is 21％higher than that of the DDQN bench-mark algorithm,and the training speed is 42％and 34％higher than that of the DDPG and A3C algorithms respectively.关键词
