This anomaly refers to the fact that when one client throttles back its data rate, the throughput of all clients serviced by the same Access Point (AP) suffers substantially: the fast clients see their throughput decreased to a rate comparable to that of the slow client.
When some clients experience poor channel conditions and therefore communicate at a lower data rate, this severely impacts the throughput of all clients in the network.
To support an open access femtocell architecture, a compensation scheme is needed, since the use of an open access femtocell architecture would decrease the effective throughput of private clients.
The two criteria for selecting intervention facility selection were: i) good performance in the previous study and ii) high throughput of FP clients (≥100/month).
We can observe from these figure that the throughput of the client remains almost unchanged and independent of α.
We also proposed an algorithm that determines how frequently the coop RTS frames are sent from the provider according to the required throughput of the client [4, 5].
Here, if the probability that packet loss occurs is the same for all STAs in the network, the following relationship is obtained from Equation 4, which represents the relationship between the actual and referenced throughput of the client: (7).
We see in the figure that the throughput of the client is successfully controlled almost equally to Δ r without affecting that of the other STA. Figure 13 Throughput for each STA versus Δ r with one additional TCP flow other than client and provider (other).
Figure 12 Average throughput of ten wireless clients, while five clients transmit two UDP downlink flows and the rest transmits one UDP downlink flow each (the upper part: with standard DCF scheme, the lower part: with our WLAN-ATC scheme).
Latency, throughput, bandwidth, number of clients, number of servers or type of connection (e.g., wifi, bluetooth, GSM) are typical variables.
