“…Although excellent research has been conducted on UAV communications, there are few works focusing on UAV-assisted emergency communication networks in disasters [26][27][28][29]. Merwaday et al [26] used a genetic algorithm to get the best location of the UAV, thereby improving the network throughput.The problem that maximizing the number of service users under limited UAV battery capacity by optimizing the flight path was proposed in [27].…”

“…There are three different network models corresponding to three scenarios: First, UAV is deployed to assist the surviving BSs; Second, when all ground BSs are destroyed, UAV serves as a flying base station to provide communication services; In addition, hovering UAVs are used as multi-hop relays to exchange the information between the disaster area and outside. The collection and transmission of user information in emergency scenarios considering natural environment and UAV energy consumption constraints were investigated in [29]. In order to improve the QoE and shorten the flight time of UAV, a path optimization scheme including hover point selection and mobility planning is proposed and solved by convex optimization method.…”

“…A robust routing scheme is introduced to guarantee communication stability during the process of delivering the distress information. A novel UAV path planning frame work is introduced in [ 12 ] for emergency messages transmission and collection. The motion and transmission power of the UAV is optimized while visiting access points for sending and collecting the emergency messages.…”
