On Fairness, Delay and Signaling of Different Approaches to Real-time Congestion Control

چکیده
This paper touches three different topics regarding congestion control for real-time flows. First the difference between loss-based, receive-side delay-based and send-side delay-based congestion control algorithms is discussed. Next the difficulties with self-fairness is discussed, focusing on a particular scenario where, for example, Receive-side Real-time Congestion Control (RRTCC) [1] is shown to have problems.

Congestion Control Approaches Applied to Wireless Sensor Networks: A Survey
Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...

متن کاملTraffic Priority Based Adaptive and Responsive Congestion and Rate Control for Wireless Mesh Networks
Congestion Control in Wireless Mesh Networks (WMNs) has been a widely studied context oriented utilization maximization problem. The traffic in WMNs has a wide range of variations (i.e. bandwidth, jitter, delay jitter sensitive applications) due to its use as the backbone network for accessing Internet. Eventually, traffic variation contributes to channel saturation and may bring up congestion ...
متن کاملDesign and analysis for TCP-friendly window-based congestion control
The current congestion control mechanisms for the Internet date back to the early 1980’s and were primarily designed to stop congestion collapse with the typical traffic of that era. In recent years the amount of traffic generated by real-time multimedia applications has substantially increased, and the existing congestion control often does not opt to those types of applications. By this reaso...
