Review on unmanned aerial vehicle assisted sensor node localization in wireless networks: soft computing approaches
(IEEE, 2022)
Artículo / Artikulua,
Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using ...
Design of high gain base station antenna array for mm-wave cellular communication systems
(Springer Nature, 2023)
Artículo / Artikulua,
Millimeter wave (mm-Wave) wireless communication systems require high gain antennas to overcome path loss effects and thereby enhance system coverage. This paper presents the design and analysis of an antenna array for ...
