Hello, I am having problems with packet generation in a Hierarchical
simulation.
When I receive an udp packet, I get the Power of the received packet Pkrxpw,
and if the power is lower than a Threshold, I have to generate a packet of
another type and send it to a node.
In mac 802_11.cc recv method is the place where y get the packet power and
depending on it I call a send method of an Agent I have created similar to
ping of marc greiś tutorial that creates a packet like this:
hdr_ip* hdrip = hdr_ip::access(pkt);
hdr_mih* hdr = hdr_mih::access(pkt);
hdr_cmn* cmn = hdr_cmn::access(pkt);
hdr->size_LD=50;
cmn->ptype()=PT_PING;
// Send the packet
Scheduler::instance().schedule(target_, pkt, 0.0);
But I get a message :Scheduler: attempt to schedule an event with a NULL
handler. Don't DO that.
I have tried to set ports, daddr and srcaddr in tcl and in c++ code but I
get the same message.
I have tried to use send(p,0) and then I get a segmentation fault...
I don know if the problem could be that I am sending the packet while the
udp packet is being sent or it is another thing.
Help would be appreciated.
Best Regards,
Pablo
