Accidentally shot your hand with a nail gun during a DIY project? You get a doctor immediately. Someone just got run over by a truck?
They get a doctor immediately too. Somebody else shows up with a broken arm? The same thing happens on your network at home—bandwidth is given out as needed, without much regard for what each application is doing. There are hundreds of different routers out there with wildly different firmware and capabilities. Some routers have Quality of Service settings that are as simplistic as allowing you to prioritize the traffic from one computer over another.
Some have you specify what kind of services you want to prioritize e. For demonstration purposes, we will be enabling Quality of Service rules on a router flashed to run the versatile DD-WRT third-party firmware.
Before you even open your admin page, think about your goals. What are you attempting to accomplish with quality of service rules? Do you want to ensure that your home office computer always has priority over all the other devices in the house e. Do you want to prioritize Netflix so your streaming video is always smooth?
For residential use, QoS rules should be selective and as minimal as possible. If that resolves your network issues, then stop there. If not, you can continue with another rule. Save for the most simple of QoS systems, nearly every QoS setup will ask about your upload and download speed to set the limits on how much bandwidth users and services can gobble up. Absolutely do not rely on the advertised speed your ISP says your account has.
Test it yourself to get a true measurement. First, stop all high-bandwidth activities on your network: stop large downloads, stop streaming Netflix, and so on.
You want an accurate picture of your real available upload and download bandwidth. Next, visit speedtest. Ideally, you should run this test while your computer is hooked up with an Ethernet cable, or at the very least a fast Wi-Fi connection using modern wireless technologies like Wireless N or Wireless AC. Once you have your results, convert the numbers from Mbps to Kbps as the QoS control setup usually asks for these values in kilobits and not megabits.
You can do so by multiplying each value by Thus, in our above example, we achieved 42, Kbps for our download bandwidth, and 3, Kbps for our upload bandwidth. Quality of Service Games for Spectrum Sharing Abstract: Today's wireless networks are increasingly crowded with an explosion of wireless users, who have greater and more diverse quality of service QoS demands than ever before.
However, the amount of spectrum that can be used to satisfy these demands remains finite. This leads to a great challenge for wireless users to effectively share the spectrum to achieve their QoS requirements.
This paper presents a game theoretic model for spectrum sharing, where users seek to satisfy their QoS demands in a distributed fashion.
The transmitters adapt their parameters power, frequency, and spreading gain autonomously and in a decentralized way, without exchanging any information. This adaptation is made possible thanks to the feedback of local information on the channel statistics provided by their receiver. A blind satisfaction response algorithm is also proposed, which requires only a 1-bit feedback. Realistic assumptions are made regarding the environment.
