چکیده
In unmanned aerial vehicle (UAV)-assisted data collection system, UAVs can be deployed to charge ground terminals (GTs) via wireless power transfer (WPT) and collect from them information transmission (WIT). this letter, we aim minimize the time required by a UAV jointly optimizing trajectory of scheduling for all GTs. This problem is formulated as mixed integer nonlinear programming (MINLP) which are difficult address in general. To end, develop an iterative algorithm based on binary search successive convex optimization (SCO) solve it. The simulation shows that our proposed solution outperforms benchmark algorithms.

Aviation Time Minimization of UAV for Data Collection over Wireless Sensor Networks
In this paper, we consider a scenario where an unmanned aerial vehicle (UAV) collects data from a set of sensors on a straight line. The UAV can either cruise or hover while communicating with the sensors. The objective is to minimize the UAV’s total aviation time from a starting point to a destination while allowing each sensor to successfully upload a certain amount of data using a given amou...
متن کاملTrajectory Optimization for Completion Time Minimization in UAV-Enabled Multicasting
This paper studies an unmanned aerial vehicle (UAV)-enabled multicasting system, where a UAV is dispatched to disseminate a common file to a number of geographically distributed ground terminals (GTs). Our objective is to design the UAV trajectory to minimize its mission completion time, while ensuring that each GT is able to successfully recover the file with a high probability required. We co...
متن کاملEnergy-Efficient Data Collection in UAV Enabled Wireless Sensor Network
In wireless sensor networks (WSNs), utilizing the unmanned aerial vehicle (UAV) as a mobile data collector for the ground sensor nodes (SNs) is an energy-efficient technique to prolong the network lifetime. Specifically, since the UAV can sequentially move close to each of the SNs when collecting data from them and thus reduce the link distance for saving the SNs’ transmission energy. In this l...

This paper proposes a wireless powered communication network (WPCN) assisted by backscatter communication (BackCom). This model consists of a power station, an information receiver and multiple users that can work in either BackCom mode or harvest-then-transmit (HTT) mode. The time block is mainly divided into two parts corresponding to the data backscattering and transmission periods, respecti...
متن کاملSelf-powered system with wireless data transmission.
We demonstrate the first self-powered system driven by a nanogenerator (NG) that works wirelessly and independently for long-distance data transmission. The NG was made of a free cantilever beam that consisted of a five-layer structure: a flexible polymer substrate, ZnO nanowire textured films on its top and bottom surfaces, and electrodes on the surfaces. When it was strained to 0.12% at a str...
