Hello everybody.I am trying to implement some mobility models but as a first stage I have to validate the results in a 2 node simple simulation.I use on Exponential source and transform to Poisson source so that I can calculate to e2e delay.I use 100Kbps bandwidth and the followings: $voip0 set packetSize_ 100 $voip0 set burst_time_ 0 $voip0 set idle_time_ 0.01 $voip0 set rate_ 8000000
The awk program I have to calculate the e2e delay gives me 112,75ms.In the contrary I try to use the M/D/1 formulas to calculate the waiting time in the buffer and the service delay to add them and have the e2e delay.But using these formulas I have 24ms delay which has a significant difference with the other.Is there another kind of delay in wireless which i don't use so there is this gap?Could anybody help me with this?I use an arrival rate of 80kbps so that I have a load of 80%(idle time=packet size(bits)/arrival rate(bits)).I know that the propagation delay is very small although i did not set it anywhere.I would really appreciate any ideas or help.Thanks in advance! -- View this message in context: http://www.nabble.com/Wireless-delay-tf4118679.html#a11713127 Sent from the ns-users mailing list archive at Nabble.com.
