[ns] From mac-802_11, how to access member function in wireless-phy
Hi, all. From mac-802_11, I want to call node_sleep()- a function in wireless-phy. The variable netif_ or downtartget_ is used as pointer to the object of wireless-phy. But the compiler always tell me that the node_sleep() function does not exit. Why? I need your help. Any suggestion will be welcom. Vandlu - 雅虎邮箱，您的终生邮箱！
[ns] Error bailing in Tcl::eval
Dear ns users,
I got a problem when using ns2 simulator
When I excute ns MyCode.tcl for a while
It stopped and leave an error message bailing in Tcl::eval
The error message seems to be written in tclcl-1.19/Tcl.cc as follows
void Tcl::eval() {
char* p = bp_;
bp_ = p + strlen(p) + 1;
/*XXX*/
if (bp_ = buffer_[1024]) {
fprintf(stderr, bailing in Tcl::eval\n);
assert(0);
exit(1);
}
eval(p);
bp_ = p;
}
It's weird that I never use eval command in my code.
My code is a wireless application written in Tcl and there are about
200 nodes in it.
When I decrease the number of node to about 10~50, this error
sometimes disappeared .
The version of ns2 is 2.33
How should I solve this problem?
Thanks!

[ns] Simulation halting after ARP request in Wifi, ns3
Hello ns users,
I am simulating a small Adhoc-wifi network of 4 nodes in ns3. Two nodes
are OnOff sources and other two of them are OnOff sinks. I am starting two
source nodes at the same time. The problem I am facing is that, after ARP
request the simulation just halts, not even a single data packet is sent.
Following is my script:
#include iostream
#include fstream
#include ns3/core-module.h
#include ns3/common-module.h
#include ns3/node-module.h
#include ns3/helper-module.h

StringValue (0)); // enable rts cts all the time.

return 0;
}
Following is content of out.tr after simulation:

It appears that the ARP request does collide (I dont' know why?) since the
node 3 is receiveing the ARP request sent by node 0 for node 2. But
simulation doesn't carry on. This is the whole trace file that I have
shown.
Please help me in simulating more than 1 application in wifi ns3 because
any example does not show us how to do so.
Any help would be greatly appreciated.
Thank you,

[ns] ZigBee routing simulation
Hi All, I am new to ns2 and I am working on a project related to ZigBee routing. After searching the web, I found Jianliang Zheng had developed an IEEE 802.15.4 module for ns2 (http://ees2cy.engr.ccny.cuny.edu/zheng/pub/). He also mentioned that ZigBee routing is now maintained by ZigBee NWK WG and no longer included in this release. But I cannot find the implementation by ZigBee WG. Can anyone give me some advise on if there is any public available implementation of ZigBee routing? Thanks in advance! Best, Ning
[ns] ns-2 and multicell
Does NS-2 suport the frequency reuse of Wimax model? I don't care about the version only if it is possible. If that so how can I do that? Because I thing that we only initialize one frequency for all the BS in the bigining. Thanks ___ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
