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
