Based on the error:
can't read topoInstance_: no such variable
while executing
$node add-interface $chan $propInstance_ $llType_ $macType_ $ifqType_
$ifqlen_ $phyType_ $antType_ $topoInstance_ $inerrProc_
I guess that you did not creat an area so that the mobile node will be able
to move
Hi all,
I am working on an interesting Mac protocol for wireless network where the
tower has a few antennas with different directions. They will be
transmitting alternatively to avoid conflict. In order to implement this
idea on ns2, I have to answer these questions:
1) How to use/implement
Hi everybody,
I am not sure but I think I found a bug in ns2. Specifically, it is Mac/Tdma
protocol for wireless network. In the example ~/tcl/ex/wireless.tcl, there
are 50 mobile nodes running 802.11 in 1000 seconds. I tried increasing
simulation time to 1 seconds, and it's running fine.
Hello everybody,
I am working on Mac protocol for wireless network. Let say I have node_(1)
with cbr traffic sending to node_(0). The cbr traffic will be like this:
start at 1.0, stop and 2.0, (re)start at 3.0 and stop again at 4.0 second.
My question is that: at 2.0, how Mac finds out that the
In your mymac.cc file, you need to define a Tcl class, say MacMyMacClass,
which is derived from TclClass. This class is in fact very simple, just to
let Tcl know that you have an object named Mac/mymac. After this, compiling
ns2 will do the rest of work and your Tcl code should understand your
Hello everybody,
I am trying to develop a new MAC protocol for wireless network. I am
composing two new files, say, newmac.h and newmac.cc. Out of that, I don't
know which files of ns2 that I need to modify in order to make my new
protocol work. Please advice.
Thanks so much and I look forward
