I hope you will find the answer of your question by reading the small article entitled "Understanding Wireless Range Calculations" of Chris Downey. Here is the link of that article:

thank you Raiz it was helpful i solved it based on FLD0 equation :)

IT depends on your physical layer model you are using in castalia. If you are using one of the given example scenarios then see which  propagation model they use and as said before go through this article http://electronicdesign.com/communications/understanding-wireless-range-calculations

thanks a lot it is worked, i was using tunable mac and calculated the equation based on this

hello Al-affeef,

please can you send me the code which you are used to calculate the transmission range?

there is no code ,,, there is an elements you can add to the .ini file

and that is

SN.wirelessChannel.pathLossExponent = 2.4

SN.wirelessChannel.PLd0 = 47

SN.node[*].Communication.MAC.phyDataRate = 250

SN.node[*].Communication.Radio.TxOutputPower = "-5dBm"

SN.node[*].Communication.Radio.mode = "IDEAL"

using the PLD0 equation you can change them based on the result

thanks to reply me,

i need this valus (range) to compare it wth the distance between two node and define neighbor. It is possible de calculate range transmission using PLDO equation?

thank you very much AL-afeef. 

Can i calculate the distance between each two nodes in castalia? if yes please how?

and what ideal value for receiverSensitivity  and noisefloor

you can take each node position and calculate the distance formula (you can get it online) by putting the coordinates for each node and calculate the distance 

hello sir, thank's to reply me.I have already obtain the distance using euclidian distance.

But i want to obtain the RSSI value for each node each round, possible? How?

the RSSI value can be obtained from the application module using "from network layer" function, the function pass by the value and you can receive it inside this function.

thanks for reply me, but i use the routing module. Possible in this module routing obtain rssi value?

Hello Riaz,

Thanks for the link, it's actually useful and concise, I was actually interested in the 'Wifi Range' formula. However I couldn't get any reference for it in the internet so far. could you help in this matter? did you find any other source using such formula?

Thanks in advance
