Wi-Fi throughput experiments

WI-FI throughput experiment 

In the following experiment we examine WI-FI throughput performance under various interference conditions. In all experiments the throughput is logged as performance metric.

Distributed Sensing for identify hidden terminal effect

This experiment involves two pairs of WI-FI nodes, located far away. We monitor the environment both with packet sniffing and distributed sensing via USRP sensing engine. One WI-FI group is considered system under test (SUT) while the other is considered as Interferer (INT). The transmit power of INT group is varied from 0 dBm to 20 dBm in step of 2 dBm, controlled via the benchmarking framework.

 It is seen that there is a interval where packet sniffing do not detect INT activity but distributed sensing can.

Interference caused by overlapping WI-FI channel This experiment involves two pairs of WI-FI nodes, they operate on adjacent WI-FI channels. The amount of overlapping between the two pairs are controlled via benchmarking framework. The rarget is to find out how does WI-FI react to interference caused by WI-FI activities on the adjacent WI-FI channel

Interference caused by zigbee device

This experiment involves only one pair WI-FI nodes. An narrow-band interference signal is generated by a nearby zigbee node
