Hello everyone,

Using the *TwoRayGround* reflection model and while keeping the
transmission power (Pt) fixed, (in my case 0.281838 W), i have the
following question:

When changing the receiver sensitivity by setting (RXThreshold), we can
control the transmission distance. I have built a *fifty nodes* *broadcast
scenario* in the form of two straight lines, each having a fixed *inter-nodes
distance*.

1) While setting the transmission distance to *301m* (i.e. Pt = 0.281838 W,
RXThreshold = 1.7382e-10) and *inter-nodes distance *to *300m*, broadcast
packets are received.

2) But, while setting the transmission distance to *51m* (i.e. Pt =
0.281838 W, RXThreshold = 7.39247e-08) and *inter-nodes distance *to *50m*,
broadcast packets are *NOT* received. To create a successful communication
in this scenario, i need to set-up a transmission distance of around *110m*,
through nodes exist at the distance of *50m*!

This issue keeps on repeating for all scenarios involving *small
transmission distances* and while nodes very much exists within the
transmission range.

I m very much clueless on this issue, any suggestions would be appreciated.

Regards,
Osama Rehman
