A Tutorial-Cum-Survey on Percolation Theory With Applications in Large-Scale Wireless Networks
Connectivity is an important key performance indicator and a focal point of research in large-scale wireless networks. Due to path-loss attenuation of electromagnetic waves, direct wireless connectivity is limited to proximate devices. Nevertheless, connec ...
Ieee-Inst Electrical Electronics Engineers Inc2024Self-powered transformer intelligent wireless temperature monitoring system based on an ultra-low acceleration piezoelectric vibration energy harvester
The wireless sensor nodes used for monitoring the condition of grid equipment always be powered by disposable batteries. However, it introduces disadvantages, such as inconvenient replacement, short lifespan, and envi-ronmental pollution, significantly imp ...
ELSEVIER2023WINC: A Wireless IoT Network for Multi-Noise Source Cancellation
Haitham Al Hassanieh, Jiaming Wang, Junfeng Guan
This paper introduces Wireless IoT-based Noise Cancellation (WINC) which defines a framework for leveraging a wireless network of IoT microphones to enhance active noise cancellation in noise-canceling headphones. The IoT microphones forward ambient noise ...
New York2023Investigation of Self-Sensing Techniques for Dielectric Elastomer Actuators
Self-sensing allows to use a Dielectric Elastomer Actuator (DEA) simultaneously as an actuator and sensor, without the need of external sensors. DEAs are composed of a dielectric elastomer that is sandwiched between two electrodes. If a voltage difference ...
2023Moby: A Blackout-Resistant Anonymity Network for Mobile Devices
Bryan Alexander Ford, Antoine Rault, Amogh Pradeep, Hira Javaid
Internet blackouts are challenging environments for anonymity and censorship resistance. Existing popular anonymity networks (e.g., Freenet, I2P, Tor) rely on Internet connectivity to function, making them impracticable during such blackouts. In such a set ...
