Solving Area Coverage Problem with UAVs: A Vehicle Routing with Time Windows Variation [PDF]
Robotics Auton. Syst., 2020 In real life, providing security for a set of large areas by covering the areas with Unmanned Aerial Vehicles (UAVs) is a difficult problem that consists of multiple objectives. These difficulties are even greater if the area coverage has to be sustained

Indoor Wireless Network Coverage Area Optimization
International Journal of Cyber and IT Service Management, 2022 The presence of interference has a significant impact on wireless network connections indoors. Because of the effects of multipath propagation, such as reflection, refraction, and scattering of radio waves by the structure of the building, the sent signal can usually be received in free space or via more than one pathway, and the consequence might be a

Distributed Coverage Area Reporting for Wireless Sensor Networks [PDF]
, 2009 In order to efficiently deal with subscriptions or other location dependent information, it is key that the wireless sensor network informs the gateways what geographical area is serviced by which gateway. The gateways are then able to e.g.

Self-optimized Coverage Coordination in Femtocell Networks
, 2010 This paper proposes a self-optimized coverage coordination scheme for two-tier femtocell networks, in which a femtocell base station adjusts the transmit power based on the statistics of the signal and the interference power that is measured at a ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

IEEE Transactions on Automation Science and Engineering, 2020 This article describes a Voronoi-based path generation (VPG) algorithm for an energy-constrained mobile robot, such as an unmanned aerial vehicle (UAV). The algorithm solves a variation of the coverage path-planning problem where complete coverage of an ...
