چکیده
An unmanned aerial vehicle's(UAV) trajectory optimization is an important way to improve the performance of its relay communication system. The method for UAV cascade broadcast system that uses decoding and forwarding protocols studied. Firstly, expressions signal-to-noise ratio user are given. Then, a joint distributed cascaded UAVs based on minimized maximum interruption probability proposed. transmission link two methods studied; mathematical system's traverse capacity outage single Finally, influence characteristic parameters optimal verified with computer simulations. simulation results show basically same, thus verifying effectiveness criterion.

Development and Testing of a Two-UAV Communication Relay System
In the development of beyond-line-of-sight (BLOS) Unmanned Aerial Vehicle (UAV) systems, communication between the UAVs and the ground control station (GCS) is of critical importance. The commonly used economical wireless modules are restricted by the short communication range and are easily blocked by obstacles. The use of a communication relay system provides a practical way to solve these pr...
متن کاملCellular-Enabled UAV Communication: Trajectory Optimization Under Connectivity Constraint
In this paper, we study a cellular-enabled unmanned aerial vehicle (UAV) communication system consisting of one UAV and multiple ground base stations (GBSs). The UAV has a mission of flying from an initial location to a final location, during which it needs to maintain reliable wireless connection with the cellular network by associating with one of the GBSs at each time instant. We aim to mini...
متن کاملTrajectory Optimization for Completion Time Minimization in UAV-Enabled Multicasting
This paper studies an unmanned aerial vehicle (UAV)-enabled multicasting system, where a UAV is dispatched to disseminate a common file to a number of geographically distributed ground terminals (GTs). Our objective is to design the UAV trajectory to minimize its mission completion time, while ensuring that each GT is able to successfully recover the file with a high probability required. We co...

Insurance-linked securities portfolio with the VaR constraint optimization problem have a kind of weak dominance or ordering property, which enables us to reduce the variables’ dimensions gradually through exercising a genetic algorithm with randomly selected initial populations. This property also enables us to add boundary attraction potential to GA-MPC’s repair operator, among other modifica...
متن کاملRoute Planning for Relay Uav
To expand the operative area for surveillance UAV, we propose the use of a relay UAV. The relay UAV is used as an intermediary node in a communication network: the surveillance UAV transmits data to the relay UAV, which sends it back to a ground station. In this exploratory report, we calculate the route for a relay UAV, to ensure communication at certain time points, given the route of the sur...
