Since the inception of sustainable green unmanned aerial vehicles (UAV), energy efficiency and mission-oriented intentions are the emerging turns in the UAV sector. This study aims to examine the energy efficiency and network performance of mission-based UAVs by conducting a bibliometric analysis of 1391 publications between 2005 and 2023 from the Web of Science (WoS).For a total of 383 records extracted from the Web of Science (WoS), bibliometric analysis was conducted using two techniques: performance analysis, which finds the various research elements (i.e., publication statistics, citation statistics, top publishing countries, top publishing journals, top publishing institutions, and top publishers), and science mapping, which includes relationships among the above-found research elements (i.e., citations by country, citations by journals, keyword co-occurrences, co-authorship, co-citations, and bibliographic coupling) using the open source VOS viewer and Biblioshiny. The findings showed China, India, and the USA are the most productive countries in UAV research. Future research on the use of UAVs for a variety of missions was also identified as having potential active areas of study, taking into account network performance and energy consumption in the developing mission-based UAV sector. Indian contribution and research on energy in UAVs and their network performance are feeble.
