[ns] Which version?
Hello frineds
Can any one kindly tell me which version of ubuntu, which version of ns2
and which version of gcc compiler are the correct and best ones to install
leach.
Right now i am having ubuntu 12.04, ns-23.4 and gcc version when i type gcc
-v is 4.4.7
and when i run ./test file i am getting the following errors in leach.err
file

So the problem is with gcc version, then which version must i use? and how
to install this on ubuntu 12.04 and remove the existing gcc compiler
Awaiting for reply

[ns] Problem with RTP in NS2
HI NS2 user, I'm facing 2 problems when I try to simulate RTP in NS2.
- The first, I don't known exactly what is the port of RTP, RTCP protocol
in NS2. I must write the new code in C++, so I need to know this
information. Can you tell me?
- The second, I simulate success the RTP in NS2 and create tracefile with
this example code:

In new tracefile after add the r2 node, I can't see the RTP protocol,
It just have RTCP protocol. What's the reason of this Problem?
Thanks and Best regard!
[ns] Traffic flow for mobiles nodes is it supported in nam by now ?
Hello, I checked the Marc Greis tutorial on ns2, and he said that the "traffic flow for mobilenodes is not as yet supported in nam", so right now, is it still the case ?. Actually, I did run his tcl file and it appers that it's still the case, the flow over wireless nodes doesn't show up. Does that means that anything were not involved yet. Actually, i'm working on a project wchich i need to see and demonstrate the flow between wireless nodes. Is anyone have any idea on how to succeed it ?. Have a good one ! MAXA Tel:+(262)693915938

[ns] About wireless node range
How can I increase the transmission/reception of wireless nodes on a simulation? I tried using the tool from ns-2.34/indep-utils/propagation/threshold.cc Nodes within 230 meters can communicate, but even modifying the Phy/WirelessPhy RXThresh_ to very big values nodes can find themselves, but can't transmit packets to them, they just send routing messages from time to time to get information about the network. (routes can be found, messages aren't sent) What can I be doing wrong? -- Flávio Arieta Netto.
[ns] Route trafic using static routes in MIH IEEE802.21
Dear all, I am doing simulations on the NS-mih-NIST patch for the handover betzeen UMTS and WIFI. My problem is that in a give time of the simulation i want explicitly change the route of the traffic. The mobile terminal is completly coverred by the two techonolgies (UMTS, WIFI) and its mobility is null. I have tried to use this tcl code line: set link [$node nexthoplink [$via id]] $src add-route [$dst node-addr] [$link head] where src: is the source node dst: is the destination via: is the intermediaire node link: is the link where the trafic is routed. But the MT maintains its connectivity with the previous access point (PoA). Anyone can help ? Best H.
