Enhanced group-based wireless ad-hoc sensor network protocol

International Journal of Distributed Sensor Networks, 2016
Communication is the major energy consumption source in wireless ad-hoc sensor networks. Thus, an efficient trade-off between the energy cost of the communication and network’s performance is a key challenge in conceiving a wireless ad-hoc sensor network.

A Wearable Brain–Computer Interface for Mitigating Car Sickness via Attention Shifting

Advanced Science, EarlyView.
Car sickness poses a major challenge in vehicular travel, yet effective nonpharmacological solutions are scarce. We developed a wearable, closed‐loop mindfulness BCI that uses real‐time EEG‐based neurofeedback to shift attention away from motion‐induced discomfort. Validated in real‐car experiments involving >100$>100$ susceptible individuals, over 83%

Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

Advanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

A survey of performance enhancement of transmission control protocol (TCP) in wireless ad hoc networks

EURASIP Journal on Wireless Communications and Networking, 2011
Transmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well.

Self-securing ad hoc wireless networks [PDF]

Proceedings ISCC 2002 Seventh International Symposium on Computers and Communications, 2003
Mobile ad hoc networking offers convenient infrastructureless communication over the shared wireless channel. However, the nature of ad hoc networks makes them vulnerable to security attacks. Examples of such attacks include passive eavesdropping over the wireless channel, denial of service attacks by malicious nodes and attacks from compromised nodes ...
