WiFox Increase Wi-Fi Performance Up to 700%

Wi-Fi network for Internet connection available free from many public places, even on the bus.
Such facilities are very useful for mobile device users. But the most frustrating is when it starts to slow down access to the Internet as more and more users on the network.
Luckily there was a group of researchers from North Carolina State University (NCSU) to develop software to solve the above problems. Called..  WiFox, this software can be installed on the network and will address the issues slowing the connection speed of the Wi-Fi is being used a lot of people. Increased throughput can reach 700 percent.
Wi-Fi performance degradation when many are using it due to the connection between the user's computer to the access point using only one channel. One channel is used in both directions, ie for sending data from the computer to the access point and vice versa. It's like a one-lane highway is used for two-way cars, are prone to congestion.
When a large number of users sending requests for data, the channel will be full and the access point will face barriers to send data back to the user. The more users the more "crowded" traffic data on the shared channel, and further down the network performance.
Software WiFox solve the above problems. This software monitors data traffic on the Wi-Fi channel and give priority to the access point to send data if there is a backlog of data. Priority is given depends on the size of the backlog - the greater the higher the priority. Acts like a traffic cop, WiFox keep data traffic to flow smoothly in both directions.
A group of researchers from NCSU has tested WiFox in Wi-Fi networks that can handle 45 users at their lab. As a result, more and more users are using the network, the higher data throughput. Increase ranging from 400 percent to 25 users and up to 700 percent when 45 users utilizing the network.
From the test results, the research team concluded that the response to user requests on average four times faster than Wi-Fi networks that do not use the software.
Interestingly, WiFox can be packaged as a software update that can be installed on Wi-Fi networks that already exist. "WiFox can be installed without disassembling the system," said Arpit Gupta, a PhD student at NCSU computer science, was quoted by the press release NCSU.
Gupta is a lead author for the paper describing the workings WiFox. Paper will be presented at the 2012 ACM CoNEXT conference, held in Nice, France, on 10 to 13 December 2012.
