low DER even in a small network #49

Closed fatemep closed 3 years ago

fatemep commented 3 years ago

Hello. I have a big problem in analysis of results. when I use the flora version 0.8 and run the network even with SF=intuniform(7,12) , TX Power=14, network size = 3000*3000 with log normal shadowing with sigma=3.57; I have low DER(about 9%)(you can try yourself!)because the most packet that arrive LoRaGateway were dropped cause of their low power(less than -137dBm). it is not reasonable and in many articles is written that DER is about 80-90% for 100 nodes(like https://ieeexplore.ieee.org/abstract/document/8580906/). could you help me?

I have found the answer myself. It is because of a wrong default parameter (d0) in lognormalshadowing.ned
