When a mobile host transmitting real-time video traffic using DCCP CCID3 moves between two wireless LAN access points with different congestion situations, it is difficult to quickly change the transmission rate according to the changes of communication environment because controlling the sending rate depends on feedback information. To solve this problem, we recently proposed a predictive rate control...
The growing use of real-time video in wireless networks, where loss rates are high yet bandwidth and CPU power of receivers can be scarce, calls for new methods to maintain good quality when packets are dropped. These methods should ideally only involve the sender and avoid increasing the amount of data sent across the network. We introduce a scheme that satisfies these requirements by selectively...
