Hi all, I have a problem in a wired-cum-wireless scenario: in my scene, there are 4 Base Station that make a square. The distance betwen 2 BS is 1000 m. I want the transmission range of every BS to be 750m, so that a mobile node doesn' t lose packets when passes from a BS to another.
I tried to modify the RXthresh_ parameter in the Phy/WirelessPhy field, according to the program threshold.cc, but in the simulations nothing changes: The mobile node begins to lose packets 200 m past the BS and resumes the connection 200 m before the next BS. In some cases, it resumes the connection 10 m before the BS. So the mobile node moves for 600 to 800 m without a connection and all the packets drop. Then i tried to modify the Pt_ variable. I put it to 1.0, 2.0 and also 20.0. It doesn' t change anything. Then I tried to modify txPower and rxPower of the BSs, I put them to 1000. But nothing changed. So I surrender to the idea that in ns2 the transmission range cannot change. If someone would show me that I am wrong, I would be much obliged. Thanks in advance!
