Deploying uncrewed aerial vehicles (UAVs) as aerial base stations (BSs) to assist terrestrial connectivity has drawn significant attention in recent years. Alongside other UAV types, drones can be rapidly deployed in the air to bring Internet access to a region when serving users via terrestrial BSs is not feasible.
Practical use cases for aerial base stations UAVs are highly desirable in today's communication systems due to their agility and mobility, low-cost of implementation and ability to move to higher altitudes to provide LoS communications, .
Recently, unmanned aerial vehicles (UAVs) have been reported a lot as aerial base stations (BSs) to assist wireless communication in Internet of Things (IoT). However, most results for UAV deployment require uniform access requirements and obstacle-free environment.
This article investigates a communication system assisted by multiple UAV-mounted base stations (BSs), aiming to minimize the number of required UAVs and to improve the coverage rate by optimizing the three-dimensional (3D) positions of UAVs, user clustering, and frequency band allocation.
This paper investigated the 3D deployment problem of multi-UAV mounted BSs for UEs with non-uniform access requirements in obstacle-laden environment. A three-step algorithm was developed to achieve full coverage of all UEs with guaranteed QoS requirements.
