Abstract
Wireless networks such as WiFi (802.11) enable new kinds of applications when users are in a mobility situation, including audio/video streaming. However, the total available bandwidth may vary greatly because of entwork usage and physical interferences in the 2.4GHz band. This may lead to a point where the bandwidth is overused causing a quality of service degradation. Based on the programmable node concepts and the scalable coding techniques, the functionality of a WiFi access point was extended to make it “active” and adaptive to the network conditions. Furthermore, since a WiFi access point is "light", the focus was to design this gateway as light as possible. Thanks to a module that monitors the wireless network and to a module that can truncate packets when the network is overused, the network-aware wireless gateway can adapt data according to the network bandwidth. This paper describes the designed scalable coding, the programmable wireless gateway and presents an evaluation of the gain of bandwidth after truncation of packets.
