Novel Dynamic Buffer Sizing Approach for Estimating and Increasing Throughput of 802.11 Based Networks

In this paper, the authors regard as the sizing of network buffers in 802.11 based networks. UDP (User Datagram Protocol) based networks face a number of fundamental issues that do not arise in TCP (Transmission Control Protocol) based networks. These include that the mean service rate is dependent on the level of channel contention and packet inter-service times vary stochastically due to the random nature of CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) operation. They find that these considerations lead naturally to a requirement for adaptation of buffer sizes in response to changing network conditions. They present novel dynamic buffer sizing algorithm that achieve high throughput while maintaining low delay across a wide range of network conditions. Experimental measurements demonstrate the utility of the proposed algorithms in a production WLAN (Wireless Local Area Network).
