Extending the Real Rime Congestion Control Mechanism for Multicast Applications over 3G Wireless Networks

چکیده
In this paper we introduce a real time congestion control mechanism to multicast the multimedia applications. The key challenge in the design of this mechanism is to calculate the rate of feedback messages by various receivers; appropriate feed back suppression, scalable round trip time measurements & ensuring that feedback delays in the control loop do not adversely affect fairness towards competing flows. Major contributions are the feedback mechanism and provide an end-to-end multicast congestion control schemes. We improve the well-known approach for multicasting, by using exponentially weighted random timers by biasing feedback for low-rate receiver and preventing the response implosion. We evaluate the design using simulation and demonstrate the results for multicast transmission of multimedia data. KeywordsGECM; ROTT; Congestion; ECN; TFMCC; TFRC; RBRC.

متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
