Optimal Trajectories of a UAV Base Station Using Hamilton-Jacobi Equations
Marceau Coupechoux, Jérôme Darbon, Jean-Marc Kélif +1
We consider the problem of optimizing the trajectory of an Unmanned Aerial Vehicle (UAV). Assuming a traffic intensity map of users to be served, the UAV must travel from a given i…
Optimal Trajectories of a UAV Base Station Using Lagrangian Mechanics
Marceau Coupechoux, Jérôme Darbon, Jean-Marc Kélif +1
In this paper, we consider the problem of optimizing the trajectory of an Unmanned Aerial Vehicle (UAV) Base Station (BS). We consider a map characterized by a traffic intensity of…
Uplink Energy-Delay Trade-off under Optimized Relay Placement in Cellular Networks
Mattia Minelli, Maode Ma, Marceau Coupechoux +3
Relay nodes-enhanced architectures are deemed a viable solution to enhance coverage and capacity of nowadays cellular networks. Besides a number of desirable features, these archit…
Optimal Relay Placement for Capacity and Performance Improvement using a Fluid Model for Heterogeneous Wireless Networks
Jean-Marc Kelif, Marceau Coupechoux, Marc Sigelle
In this paper, we address the problem of optimal relay placement in a cellular network assuming network densification, with the aim of maximizing cell capacity. In our model, a fra…
