flow monitor shows low PDR (if Simulation schedule)

[Sohail Ahmad]

Dear All,

I created a scenario where 1 eNb node and 5 APs are deployed, each AP has 5 UE nodes and these nodes are hybrid nodes (WiFi module + LTE module). Each node sends packets to its associated AP for the first 5 second, and after first 5 seconds, at each second simulation is scheduled to a function where signal strength is checked I used following code to

for (double delay = 05; delay <= simTime;){

        Simulator::Schedule(Seconds (delay), &signalStrength);

        delay += 01;

    }

 

Packets are switched successfully. Sir I used flow monitor to get results of packets to get PDR. If I run simulation for more than 10 seconds, if required I post the whole script,

flow monitor shows

Delay Sum = 0

Mean Delay = nan

Sir I am getting very low PDR even I used higher data rate, packets are lost after some flows, please guide me where is the problem and what should I have to do, or suggest me some example or thread.

Thanks
