Re: [ns] Wireless simulation with high speed nodes

2006-10-24 Thread Miguel Sepulcre Ribes
Hi, Have you tried to plot the received power of node1 against the distance to node0? I think that an exponent equal to 2.5 for the log-distance pathloss model could allow the signal to reach long distances. If despite of the Ricean fading your average received power is always very high, y

You could run a script like: for parameter1 in 0 1 2 3 4 do for parameter2 in 10.0 15.0 do ns myfile.tcl -parameter1 $parameter1 -parameter2 $parameter2 done done Don't forget to add the parameters that you want to be modified in your .tcl file: proc getopt {argc a

This link may answer the first question: 4.2.5 Precision of the scheduler clock used in ns: http://www.isi.edu/nsnam/ns/doc/node37.html What do you mean with "And 1 simulation second traslate directly into 1 realtime second" ? Regards Miguel Keita Rose <[EMAIL PROTECTED]> esc

You can set a threshold (in bytes) with the instruction: Mac/802_11 set RTSThreshold_ If the packet length is larger than RTSThreshold_, the RTS/CTS exchange process preceds the data transfer. Regards Miguel boygullit <[EMAIL PROTECTED]> escribió: Hi As we know DCF is used by default
