Energy-Efficient Trajectory Design for UAV-Enabled Communication Under Malicious Jamming

In this letter, we investigate a UAV-enabled communication system, where UAV is deployed to communicate with the ground node (GN) in presence of multiple jammers. We aim maximize energy efficiency (EE) by optimizing its trajectory, subject UAV's mobility constraints. However, formulated problem difficult solve due non-convex and fractional form objective function. Thus, propose an iterative algorithm based on successive convex approximation (SCA) technique Dinkelbach's it. Numerical results show that proposed can strike better balance between throughput consumption optimized trajectory thus improve EE significantly as compared benchmark algorithms.
