A Systematic Review of Performance Determinants in UAV-Assisted Cooperative Communication Systems

Abstract

Unmanned aerial vehicles (UAVs)-assisted communication systems present a cost-effective solution for ad-hoc network operations. In mission-critical applications like surveillance, UAVs can function as aerial relays, particularly when multiple UAVs collaborate. This collaborative approach proves to be more efficient and economical in accomplishing assigned tasks compared to the use of a single UAV. Achieving reliable operation, however, requires addressing significant issues associated with deploying UAVs in mission areas. This article explores the opportunities offered by a cooperative relaying topology in a multi-UAV system, shedding light on specific challenges related to its implementation and providing communication reliability. Additionally, the article delves into the system evaluation metrics essential for measuring the performance of such network and discusses simulation tools suitable for this purpose.
