Towards Enabling Unmanned Aerial Vehicles as a Service for Heterogeneous Applications

The increasing use of unmanned aerial vehicles (UAVs) invarious commercial applications, such as precision agriculture andaerial remote sensing, is fast contributing to a significant growthin the UAV market. Also, it is crucial to provide continuous cov erage after failures of wireless network components or additionalbandwidth in high traffic situations. By introducing the concept ofUAVs as a service (UaaS), we propose a novel framework, dubbed 3S, consisting of four phases: Demand, decision, deployment,and service. The main objective of this framework is to provide arealistic and streamlined approach to support the implementationof the UaaS paradigm. The technical problems involved include de termining the type and number of UAVs to be deployed and theirfinal locations (e.g., hovering or on-ground). They also include thetrajectory planning, possibly several times, between charging sta tions and deployment locations. We present the application of the 3S framework to two case studies with the goal of providing wire less connectivity services to (i) static users after failures of wirelessnetwork components, including long-term and short-term failures,and (ii) dynamic users in wireless relaying systems.

In this article we propose using mathematical models of signals in wireless communication systems with autocorrelation reception of modulated ultra-wideband signals. For the transmission of information content, the method of positional-time coding is used, in which each information bit is encoded by hundreds of ultrashort pulses that arrive within a certain sequence. Comparative analysis has shown that the best noise immunity of the systems considered in this paper is the communication system, which uses the time separation of the reference and information signals.
