[ns] Wiamx Simulation Script Problem

2011-05-13 Thread sajeeb saha

Hello everyone,

I need some help regarding wimax simulation.

I
 have written a wimax simulation script with 2 base stations. My 
flow is something like this :

WL(0) -- BS(0) --- BS(1) 
--- WL(3).

But my code is always skipping BS(1).  I am not 
getting the problem. Can you help me in this regard?


I am using NIST Wimax Patch and using NS 2.31.  

Thanks in 
advance..

My code is below:

[ns] error in bcast protocol

2011-05-13 Thread Bodoor Al-fares










hi every one,

I am trying to simulate the bcast protocol orginally it is for ns2.27 but i am 
trying to run it under ns2.34 but I got those error I hope you can help me in 
this issue.

this is the error:
In file included from ./bcast/bcast.h:63,
 from ./bcast/bcast_packet.h:63,
 from trace/cmu-trace.cc:55:
./bcast/bcast_queue.h:49: error: expected ‘)’ before ‘*’ token
trace/cmu-trace.cc:1631: error: expected ‘}’ at end of input
trace/cmu-trace.cc:1631: error: expected unqualified-id at end of input
make: *** [trace/cmu-trace.o] Error 1
 

this is the ln 49 of bcast_gueue.h:
  BCASTHandler(BCAST *a) : agent(a) {LIST_INIT(pbcasts); no_bcasts=0;}

Thanx in advance,
Bodoor
  

[ns] Scenario generation in NS-2

2011-05-13 Thread Zilu LIANG

Hello guys,

Does any one knows how to generate scenarios in which the initial positions
of the nodes are the same, only the moving speed is different? Any comment
is welcomed!

Thanks in advance!

Cheers!
