I am running IOT based simulation in NetSim. And as part of my work I need to know the received power (RF) at each receiver when packets are transmitted. It would also be helpful if I could find out the Signal to noise ratio. Thank You.
Inside NetSim source code you need to make small modifications to Zigbee roject code. I think the API's to get these values are
WSN_PFY(pstruEventDetails->nDeviceID)->dTotalReceivedPower, GET_RX_POWER_mw(pstruPacket->nReceiverId, pstruEventDetails->dEventTime);
ZIGBEE_BER(SNR, &dBER, &dErrorRange);
Thank you, Ashwini Bhat
pstruEventDetails->nDeviceID - This gives the device ID of the 'current event' being executed. Am I right? Do you know if this SNR is the signal to noise ratio of the transmission from the receiving device or does it include interference from other devices as well?
The SNR in NetSim actually gives Rx power / (Noise + Interference).
Zigbee operates in such a way that at a time there is only one transmission.
However since there will be no other transmissions at the same time the interference would be zero.
