Hi

Can some one tell me how to implement and use  UM-OLSR in ns-2.33.
I followed the procedure  on 
http://masimum.dif.um.es/?Software:UM-OLSR:Using

but while running a tcl file for olsr..I got the following

Is there anyway with which I can convert the network trace captured with 
tcpdump to nam/ns format -- so that nam can design the network topology -- by

[ns] Three questions about WSN - 3D, obstacles, ZigBee

2008-07-01 Thread zoran filipovic

Hello,

I have two questions:

1. ns works with 3
dimensions (x,y,z) but Z is used just for antenna. Is it possible to
define z component for nodes as well and make 3D scenario, like hilly
field? And how is it possible? Has anyone examle script?

2. Is it possible to model obstacles? How? Any tcl example? If not,can I model 
somehow link weights?

3. can I use ZigBee (802.15.4) with ns-2? How? Any tcl example?

I am using ns-2-29 with mannasim extension for WSN.

thank you very much

[ns] difficulties in simulating 802.11 and UMTS

2008-07-01 Thread najla

Hi all,

I'am simulating a 802.11 infrastructure with 2 APs connected to a wired
network and 2 mobiles moving between the APs. I followed in my script the
model provided with NS2.33 in infra.tcl, and the 2 mobiles are configured to
make an active scan. However, the mobiles can't detect the APs even when
they are near them.

 

Could any one help me?

 

Thanking you.

 

With Regards
