Distributed and collaborative beamforming (DCBF) scheme in wireless sensor networks
(WSNs) is receiving newfound interest in recent times due to the rapid advancements in …

Collaborative beamforming is usually characterized by high, asymmetrical sidelobe levels
due to the randomness of node locations. Previous works have shown that the optimization …

A conventional collaborative beamforming (CB) system suffers from high sidelobes due to
the random positioning of the nodes. This paper introduces a hybrid metaheuristic …

In this paper, a multiuser mixed radio frequency (RF) and hybrid free-space optical (FSO)/RF
system is considered, where multiple mobile users transmit their data to an intermediate …

The communication distance and the energy of the nodes are limited in large-scale wireless
sensor networks (WSNs). Collaborative beamforming is an effective way to solve such …

The beam pattern of the virtual node antenna array (VNAA) in wireless sensor networks has
a high maximum sidelobe level (SLL), thereby causing communication interference because …

In this paper, a multi-vehicle multi-task non-orthogonal multiple access (NOMA) assisted
mobile edge computing (MEC) system with passive eavesdropping vehicles is investigated …

This paper considers unmanned aerial vehicle (UAV)-carried intelligent reflecting surface
