It can enhance the efficiency and robustness of congestion control. The survey on ECN algorithm lies in the fairness and efficiency mainly.
This mechanism based on RTP / RTCP protocol. Congestion stated is notified to the sender using ECN. RED queue management is used in the router.
Explicit Congestion Notification ( ECN ) mechanism means improving the good output by marking packets in the active queue management technique. ECN is important in the congestion control of the network.
Following the above discussion, to tackle the problem of performance degradation of the current TCP congestion control algorithm under the wireless environment, an improved wireless TCP algorithm is proposed using the cross-layer mechanism based on explicit congestion notification ( ECN ).
In this algorithm, the ecn_to_echo_bits in the acknowledge packets are first used to estimate the congestion probability in the backward path, proving that the change of Round-Trip-Time ( RTT ) is directly proportional to the change of congestion probability.
