An Energy-Efficient UAV Recharging and Reshuffling Strategy for Seamless Coverage
Xiaowei Li;Haipeng Yao;Jingjing Wang;Chunxiao Jiang;F. Richard Yu
2019 IEEE Global Communications Conference (GLOBECOM)
Year: 2019 | Conference Paper |
Cited by: Papers (5)
Due to the easy deployment, low cost and high maneuverability, unmanned aerial vehicles (UAVs) serving as aerial base stations can be efficiently deployed according to realtime situations for providing high-quality coverage, which can improve the communication efficiency and meet the requirements of green communications. However, due to the finite flight energy, a single UAV has limited capability...Show More
Joint Node Assignment and Trajectory Optimization for Rechargeable Multi-UAV Aided IoT Systems
2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)
Year: 2019 | Conference Paper |
Cited by: Papers (3)
Due to the high flexibility and high maneuverability, UAVs play an important role in constructing the space-terrestrial integrated network (STIN). However, in STIN-assisted sparse IoT scenarios, a single UAV cannot provide seamless and long-term services due to its limit cruising duration, hence the cooperation of multiple UAVs becomes a remedy. This paper studies the cooperative strategy of multi...Show More
Rechargeable Multi-UAV Aided Seamless Coverage for QoS-Guaranteed IoT Networks
Xiaowei Li;Haipeng Yao;Jingjing Wang;Sheng Wu;Chunxiao Jiang;Yi Qian
IEEE Internet of Things Journal
Cited by: Papers (57)
Due to their high flexibility, high maneuverability, and line-of-sight (LOS) predominant channel, unmanned aerial vehicles (UAVs) serving as flying base stations have received a lot of interest in emerging Internet of Things (IoT) networks. This article studies the energy-efficient cooperative strategy of rechargeable multi-UAVs for providing seamless coverage and long-term information services fo...Show More
A Near-Optimal UAV-Aided Radio Coverage Strategy for Dense Urban Areas
Xiaowei Li;Haipeng Yao;Jingjing Wang;Xiaobin Xu;Chunxiao Jiang;Lajos Hanzo
Unmanned aerial vehicles (UAVs) may be used for providing seamless network coverage in urban areas for improving the performance of conventional cellular networks. Given the predominantly line-of-sight channel of drones, UAV-aided seamless coverage becomes particularly beneficial in case of emergency situations. However, a single UAV having a limited cruising capability is unable to provide seamle...Show More
UAV Comprehensive Coverage to Users in Urban Environment
2018 IEEE 9th International Conference on Software Engineering and Service Science (ICSESS)
Year: 2018 | Conference Paper |
Cited by: Papers (6)
Unmanned aerial vehicles (UAVs)are widely used to provide network coverage in emergency situations due to their high flexibility and air-ground channel link. In urban scenarios, building blockage can severely weaken the link signal between UAV and users. Hence, how to deploy UAVs avoiding link blockage as far as possible is meaningful for improving UAV - user communication quality. To deal with th...Show More
