Abstract Unmanned aerial vehicles (UAVs) are employed as mobile relay nodes to enable timely remote monitoring by collecting information from devices and transferring the collected base station. The freshness of delivered is critical system performance, which can be quantified concept age (AoI). Nevertheless, fresher comes at cost higher energy consumption UAVs. Considering limited onboard energy, it essential strike a balance between required budget. here, both straight trajectory circular UAV considered, study problem with goal supporting data collection while minimizing UAV. formulated multi‐criteria optimization jointly considering aging information, planning To solve problem, solution procedure find sequence Pareto‐optimal points proposed. Simulation results demonstrate curve, yields energy‐efficient for collection.
