“…Moreover, UAVs offer distinctive advantages, including high mobility, cost‐effectiveness, and deployment flexibility, which have propelled UAV‐assisted wireless communication networks into a burgeoning research field embraced by both academia and industry. The utilization of UAVs as aerial mobile relays in cooperative communication systems has been widely discussed and investigated in the open literature 3 . Aerial mobile UAV relays can establish favourable line‐of‐sight (LoS) connections by dynamically adjusting their position.…”

Motivated by the timely need for fresh updates in time‐critical applications, this paper investigates the AoI‐driven UAV trajectory optimization for a two‐way relay network. The non‐linear simultaneous wireless information and power transfer (SWIPT) power‐splitting (PS) technique is used to provide the energy required for UAV communication considering hardware impairments. Amalgamating derived outage probability, AoI expression is obtained to evaluate data timeliness and its performance trade‐offs. Then, we optimize the trajectory of the UAV while minimizing the AoI performance within the given discretized time slot. The impact of the system parameters, that is, size of the status update, PS factor, outage probability, and UAV's position, on the AoI performance are extensively investigated.
