Power grid upgrades may cause blackouts, warns Braess's paradox
Engineers take big step toward using light instead of wires inside computers
(Phys.org)—Stanford engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead ...
New algorithm for message dissemination in decentralized networks faster than its predecessors and guarantees delivery
Ad hoc networks—communication networks set up on the fly by mobile sensors—pose problems that ordinary office networks don't. Ad hoc networks are usually decentralized, meaning that no one node knows ...
Multimode waveguides bring light around corners
(Phys.org)—Light has become one of our most powerful servants, carrying information ranging from a chat room "LOL" to an entire digitized movie through hundreds of miles of fiber optics in seconds. But ...
Researchers develop new wireless technology for faster, more efficient networks
"Wireless communication is a one-way street. Over." Radio traffic can flow in only one direction at a time on a specific frequency, hence the frequent use of "over" by pilots and air traffic controllers, walkie-talkie ...
Today, data traveling over the Internet are much like crates of oranges traveling the interstates in the back of a truck. The data are loaded in at one end, unloaded at the other, and nothing much happens ...
Taking the Internet underwater
(Phys.org) —Wireless networks span the globe. But like a frightened toddler, they don't go underwater.
S. Korea tests 'electric road' for public buses
A South Korean city has begun testing an "electrified road" that allows electric public buses to recharge their batteries from buried cables as they travel.
Reliable communication, unreliable networks
Now that the Internet's basic protocols are more than 30 years old, network scientists are increasingly turning their attention to ad hoc networks—communications networks set up, on the fly, by wireless devices—where ...
Visio.M e-mobility project unveils remote control driving technology
Fully autonomous cars may still be the stuff of science fiction. Remote driving technology, however, may be much closer than we think. Scientists at the Technische Universität München believe that full-size ...
Computer system automatically generates TCP congestion-control algorithms
TCP, the transmission control protocol, is one of the core protocols governing the Internet: If counted as a computer program, it's the most widely used program in the world.
Wiggling worms make waves in gene pool
The idea that worms can be seen as waveforms allowed scientists at Rice University to find new links in gene networks that control movement.
It's often said that we live in an age of increased specialization: physicians who treat just one ailment, scholars who study just one period, network administrators who know just one operating system.
Shifting the Internet into high gear
(Phys.org) —A new-generation analog-to-digital converter (ADC) developed by a joint IBM-EPFL team has the potential to greatly increase the speed and volume of data that can be transferred over the Internet.
