Re: [ns] Accessing object created in Tcl from C++
Hi Vijay, The problem described by you seems to be something very specific to your codei mean to the modifications you have doneso it is really not possible for me to tell you anything straightforward on the matter. I am sure if you take a deeper look into your code and try and understand what is it that a wireless node is expecting and I am not providing, you will definitely be able to work things out. Sorry and All the Best. - Prashant Vijay Ghorpade wrote: Hi Prashant, I have a problem with ns-2 When i make some change in the node class and compile the code it doesnot give any errors. The wired scripts also work. But when i try with wireless scripts it gives either segmentation fault or event UID not found error. Why it is so. Can you help me out Vijay On Fri, 18 Aug 2006 Prashant Batra wrote : Hi Shafiq, To access a variable declared in your TCL script, you can use the following method :- Tcl tcl = Tcl::instance(); tcl.lookup(char* s); The 'lookup()' function of Tcl class takes a pointer to the name of the variable in the TCL script and returns you a TclObject class object, which you can further typecast into your specific object type and use. - Prashant Shafiq Hashmi wrote: Hello all, Is it possible to access an object of Agent/RCAgent, created in Tcl, from another C++ class.

Re: [ns] error in multi_udpflows.tcl its urgent...
Hi,
the problem appears if the installation has not been 100 percent
successful wrt the tcl files. Please check all settings described in
README again, especially in Makefile.in, ns-lib.tcl, and ns-mac.tcl.
BR,
Sven

[ns] I have a problem in simulation .... while the compilation is okay
Dear ns-users;
I use ns-allinone-2.29 under cygwin/winXP.
I faced the following problem after changing the MAC in ns2.29.
during the simulation I got the follwoing Error:
Scheduler: Event UID not valid!
the code is here ( I made the changes just in the recv() function):
void Mac::recv(Packet* p, Handler* h)
{
printf( \n Now you are in Mac layer);
int i;
int k;
int r;
int errcount;
int recR;
//===start=== BiLaL
if (hdr_cmn::access(p)-direction() == hdr_cmn::UP)
{
if (hdr_mac::access(p)- ftype() == MF_FEC_R)
{
Red_= hdr_mac::access(p)-Red();
drop(p);
printf( \n Redundancy is CHANGED);
return;
}
if (hdr_cmn::access(p)-size()%framesize_ != 0) k=1;
else k=0;
k +=(hdr_cmn::access(p)-size()+ Red_)/framesize_ ;
for (i=0;i= k; i++)
{
r=(rand()%100);
if (r = p_) errcount++;
}
if (errcount Red_)
{
drop(p);//Packet::free(p); //discard the received packet
printf(\n one packet has been lost);
Packet *p = Packet::alloc();
hdr_cmn* ch = HDR_CMN(p);
hdr_mac* mhr = HDR_MAC(p);
mhr-ftype()=MF_FEC_R;
ch-uid() = 0;
ch-ptype() = PT_MAC;
ch-iface() = -2;
ch-error() = 0;
ch-size()=64;
ch-direction() = hdr_cmn::DOWN;
// *** changing the Redundancy strategy
mhr- Red()= errcount;
callback_=h;
mhr-set(MF_FEC_R, index_);
state(MAC_SEND);
printf(\n telling the sender by new R);
sendDown(p);
}
else {
// the Redundant Data must be removed
hdr_mac* mhr = HDR_MAC(p);
recR = mhr- Red();
hdr_cmn::access(p)-size()-= recR;
//===END=== BiLaL
sendUp(p);
}
return;
}
callback_ = h;
hdr_mac* mh = HDR_MAC(p);
mh-set(MF_DATA, index_);
state(MAC_SEND);
//===FEC (Redundancy)
BiLaL
printf(\n Here we adding the R to TCP packet);
hdr_cmn* ch = HDR_CMN(p);
ch-size() += Red_;
//
sendDown(p);
the problem stop inside the sendDown() function and the problem as I told
you first:
Scheduler: Event UID not valid!
I look forward to your help as soon as possible.
thank you in advance
Kind Regards

[ns] CSMA/CA based on 802.15.4
Dear all, I want to simmulate Csma/ca used in 802.15.4, but I do not know how to start, I do not konw how to count the number of collision, when to start collision, I think collision can only start when more than two nodes send data to a node at the same time, another question is how I can change CW, BE and NB in source code .so that another question is how I know what I simulate is Csma/ca.

I am just confused because I have seen trace format like TCP 100 which means 100 bytes transferred. I want to calculate the packets send and packets received using diffusion protocol. I am getting the diffusion 0 at AGT layer. I would be grateful if you could give me some idea how to calculate the total data sent and total data recieved by a particular node. looking forward for your reply.
