hello,
if I understand correctly , you want to do like what has done in back off time.
for it you should define timehandler function and use a variable from this
function
then you should useresched or sched receive function to save time and after
specific time , timeout() function will call so you can define what you want to
do after this period in timeout function.
like below example:
void UCBAgent::newTimer() {
hdr_ucb* flood;
double delay = Random::uniform(minDelay_, maxDelay_);
// Create a new packet
if ( !rebroadcast_ ) {
rebroadcast_ = allocpkt();
}
flood = hdr_ucb::access( rebroadcast_ );
flood->msg_src = myID_;
flood->total_store_time = 0;
flood->total_store_time+= delay;
delsnd_timer_.resched( delay ); // after delay time , timeout() function
will call
}
void UCBAgent::timeout() {
if ( rebroadcast_ ) {
send( rebroadcast_, 0 );
}
}
I hope it will be helpful.

Subject: [ns] Fwd: How to set a timer to check condition in recvRequest()
Hi everyone,
As a part of my project in MANETs, I have added an entry named Flag 1 in
the existing neighbor table in aodv. Whenever a node X receive a request
from node Y, Flag 1 corresponding to will get set as "1". Actually this
flag has to be set if the RREQ send by X reaches X itself via rebroadcast
from its neighbors, within a certain time period.
How can I check this condition? Is there any way to store the time at
which the RREQ packet has been send first and we can make use of that from
recvRequest() function? In the recvRequest() i am able to print the node
from which the RREQ is received. But how can I check that if the received
RREQ is the one actually send by node X and has obtained by it within a
timeout? I want this checking since I have to make sure that all the
neighbors are responding.
Can anyone please help me with this. Thanks for y.our valuable time
Regards,
Sony
