WiFox “Congestion Handler” Could Speed Up Wi-Fi Without Hardware Tweaks

In practice, most Wi-Fi routers offer much less than their advertised speeds. Although I’ve seen some fast throughput in my time, most of the gear we use is rated for much higher than network traffic will allow. Some researchers at NC State University , however, have figured out a way, in software, to improve throughput by 700%.

These claims – often put forth by researchers and rarely implemented in real life – are pretty bold but entirely feasible. The system, called WiFox, works best on congested networks like those found at airports, hotels, and events. When the latency gets too high on the network, WiFox begins by taking control of the channel, sending out backlogged packet, and clearing the main channel. Once things have been sent over, the latency should drop considerably as data begins to flow normally.

Using 45 devices connected at once, the researchers saw a 700% increase in throughput, which is impressive given what happens when a scrum of users tries to access the same access point at public locations.

“In effect, the program acts like a traffic cop, keeping the data traffic moving smoothly in both directions,” according to the researchers.

The research team, student Jeongki Min and Professor Injong Rhee, will present their findings at the ACM CoNEXT 2012 in December.

NC State University's WiFox could improve public WiFi performance by up to 700 percent

If you’ve ever swallowed your pride and bit the bullet on hotel WiFi, you’ve probably felt the sluggish pull of other users dragging down your connection speed. Coffee shops, airports and other heavily impacted public hotspots can slow to a crawl as they try to mete out data to dozens of users sharing a single channel. All hope is not lost, however — a team at NC State University are about to release a paper detailing a technology that could bolster WiFi data throughput performance by up to 700 percent. The team is calling their technology WiFox, and it’s already made their local test network four times faster, on average. WiFox keeps track of the amount of traffic gumming up a WiFi channel and actively assigns priority access to avoid a traffic jam of data requests. Fixing sluggish hotspots should be a snap, too — Student and lead author Arpit Gupta says WiFox could be “packaged as a software update that can be incorporated into existing WiFi networks.” The full paper will be presented at ACM CoNext next month in Nice, France. Can’t wait? Feel free to click on the source and ogle the paper’s abstract.
