WHISPER: A Location Privacy-Preserving Scheme Using Transmission Range Changing for Internet of Vehicles [PDF]
Sensors, 2021 Internet of Vehicles (IoV) has the potential to enhance road-safety with environment sensing features provided by embedded devices and sensors. This benignant feature also raises privacy issues as vehicles announce their fine-grained whereabouts mainly ...

Long-Range Big Quantum-Data Transmission. [PDF]
Physical Review Letters, 2017 We introduce an alternative type of quantum repeater for long-range quantum communication with improved scaling with the distance. We show that by employing hashing, a deterministic entanglement distillation protocol with one-way communication, one ...

On the Selection of Transmission Range in Underwater Acoustic Sensor Networks [PDF]
Sensors, 2012 Transmission range plays an important role in the deployment of a practical underwater acoustic sensor network (UWSN), where sensor nodes equipping with only basic functions are deployed at random locations with no particular geometrical arrangements ...

Collective cell durotaxis emerges from long-range intercellular force transmission [PDF]
Science, 2016 The ability of cells to follow gradients of extracellular matrix stiffness—durotaxis—has been implicated in development, fibrosis, and cancer. Here, we found multicellular clusters that exhibited durotaxis even if isolated constituent cells did not. This

Extended short-range airborne transmission of respiratory infections
Journal of Hazardous Materials, 2021 Debate and scientific inquiries regarding airborne transmission of respiratory infections such as COVID-19 and influenza continue. Health authorities including the WHO and the US CDC have recognized the airborne transmission of COVID-19 in specific settings, although the ventilation requirements remain to be determined.

Energy-Efficient Algorithm for Sensor Networks with Non-Uniform Maximum Transmission Range [PDF]
Sensors, 2011 In wireless sensor networks (WSNs), the energy hole problem is a key factor affecting the network lifetime. In a circular multi-hop sensor network (modeled as concentric coronas), the optimal transmission ranges of all coronas can effectively improve ...

Ant-Based Transmission Range Assignment Scheme for Energy Hole Problem in Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2012 We investigate the problem of uneven energy consumption in large-scale many-to-one sensor networks (modeled as concentric coronas) with constant data reporting, which is known as an energy hole around the sink.
