UAV Placement and Relaying for Wireless Communications
Fri, 20/09/2019 - 11:00 to 12:00

Speaker:
Dr Yunfei Chen
Affiliation:
University of Warwick
Synopsis:
Unmanned aerial vehicles (UAV) have gained great popularity in recent years due to their low cost and high mobility. In communications, they are mainly used as either aerial base station or relay. In this talk, UAV communications will be discussed. Firstly, UAV placement issue will be discussed. A higher altitude gives a better line-of-sight condition but leads to higher path loss from the ground user. Optimum altitudes exist in different application scenarios, depending on the path loss model. Secondly, the use of a UAV swarm with multiple UAVs as relays will be studied. Two typical settings of using multiple UAVs in a multi-hop single link and in multiple dual-hop links will be optimized and compared to find the best setting for different scenarios.
