FLoCAD: Fuzzy Logic Controlled Video Streaming with Congestion Avoidance using Delay and Packet Loss

Accuracy in determining congestion level is a big factor in designing efficient rate adaptive networked multimedia. This paper proposes measuring one-way delay of video packets to serve as incipient network congestion indicators. The delay is potentially used in conjunction with packet loss rate as input to a fuzzy logic controller. The controller efficiently adapts the sending rate of the application to the level of network congestion. The paper demonstrates that using delay to signal imminent congestion and packet loss to signal full-blown congestion is a means of accurate and timely adaptation to varying network conditions.
