[ns] Access to Agents
Hello, is it possible in C++ to access the agents of a node when I have the node ID or rather the name of the nodeobejct(e.g. o_14)??? - Or to find out which Agents belong to my node? jana -- Echte DSL-Flatrate dauerhaft für 0,- Euro*.

[ns] Change field in AODV routing protocol header
I urgently need help with the following problem: I use the AODV routing protocol with a modified field (the reserved field) in the packet header to transport special context while routing. Since every node should send different context I use AODV as an agent as well attached to every node to write the context on a variable rq_cxt_otcl (rq_context in C++). set context1 [new Agent/AODV] $ns_ attach-agent $node1 $context1 $context1 set rq_cxt_otcl 3 How can I, after creating my AODV-agent and binding the variable to the value 3, access my modified field in the routing agent packet header (AODV too) to write the value on it before sending the first packet??? Is this possible? Maybe I can access a field in the packet header out of TCL to write my context on the field directly without any AODV-agent?

[ns] How to change routing protocol packet header field?
Hello all, how can I change a field in the routing protocol packet header but only for one node. I tried it with the help of an agent but don't know how to assign the value to the packet header, since they are two different objects. I use AODV. Has anyone an idea?! jana -- "Feel free" – 10 GB Mailbox, 100 FreeSMS/Monat ... Jetzt GMX TopMail testen: http://www.gmx.net/de/go/topmail
[ns] OTCL-Linkage
I’m new to ns-2 and C++ and need help concerning OTCL-Linkage.
I’ve created a new class ContextAgent which has AODV as friendclass.
ContextAgent has two public variables that are bound to OTCL using the
bind()-function (as it is used in the Example ex-linkage.cc from the tutorial
“ns by example”). That works, as far as I could see.
My problem is, how can I call on the variables from the AODV-function
sendRequest()?
Since the ContextAgent is created in the simulation script, I don’t know the
name of it to assign it to an object of the type ContextAgent.
I send parts of my source code for better understanding. Please help!!

class ContextAgent : public Agent{
friend class AODV;
public:
ContextAgent();
int rq_context;
int rt_context;
}
//LinkObject
static class ContextAgentClass : public TclClass {
public:
ContextAgentClass() : TclClass("Agent/Context"){}
TclObject* create(int, const char*const*) {
return (new ContextAgent());
}
} class_context_agent;
//Constructor
ContextAgent::ContextAgent() : Agent(PT_AODV) {
bind("rq_cxt_otcl", &rq_context);
