| 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 |
