AbstractCellular networks based on new generation standards are the major enabler for Internet of things (IoT) communication. Narrowband-IoT and Long Term Evolution for Machines are the newest wide area network-based cellular technologies for IoT applications. The deployment of unmanned aerial vehicles (UAVs) has gained the popularity in cellular networks by using temporary ubiquitous coverage in the areas where the infrastructure-based networks are either not available or have vanished due to some disasters. The major challenge in such networks is the efficient UAVs deployment that covers maximum users and area with the minimum number of UAVs. The performance and sustainability of UAVs is largely dependent upon the available residual energy especially in mission planning. Although energy harvesting techniques and efficient storage units are available, but these have their own constraints and the limited onboard energy still severely hinders the practical realization of UAVs. This paper employs neglected parameters of UAVs energy consumption in order to get actual status of available energy and proposed a solution that more accurately estimates the UAVs operational airtime. The proposed model is evaluated in test bed and simulation environment where the results show the consideration of such explicit usage parameters achieves significant improvement in airtime estimation.

In the past few years, UAVs have evolved considerably towards real-world applications, going beyond entertaining activities. The unique features that UAVs can provide, such as flexible and easy deployment, high mobility, and mostly autonomous operation, tend to be appealing solutions in a wide variety of applications. With the number of UAVs expected to increase significantly in the forthcoming years, it is deemed mandatory to integrate innovative features of communication technologies in order to tackle several limitations and challenges that exist to date. To this end, the amalgamation of UAVs and 5G cellular networks is an auspicious solution in order to realise the full potential that the UAVs can provide as well as to effectively open up new fields of applications. The unique features that 5G cellular networks offer are utilised for supporting and providing reliable and secure UAV command and control. This chapter provides an overview of the 5G technology to support communication services for the UAV ecosystem.

AbstractUnmanned aerial vehicles (UAVs) have gained considerable interests in numerous civil applications. To push forward its potentials, cellular-connected UAVs have been introduced. Nevertheless, cellular networks face several bottlenecks such as spectrum scarcity and limited concurrent connectivity. To address these issues, non-orthogonal multiple access (NOMA) can be adopted. NOMA provides several opportunities for cellular-connected UAVs such as larger rate region, balanced performance between system throughput and fairness, and reduced delay. In this paper, we review important findings of the related studies, and outline new opportunities and challenges in NOMA for cellular-connected UAVs. Monte-Carlo simulations are then performed to analyze the new aerial user’s (AU)’s signal characteristics and evaluate the NOMA performance for co-existence of AU and terrestrial user (TU). Our preliminary results show that NOMA is a promising strategy for cellular-connected UAVs.
