The problem of simulation results - end to end delay

[Đạt Lê khánh]

Hi everyone,

This picture below is my end to end delay result when i run starnet module in inetmanet/examples/wpan. As you see that, at first, the graph goes up, reaching the highest point and then stabilize at 410.In my opinion, I think, after reaching a peak, the graph must go down to a point and then stabilize. Can you explain to me why my graph is stable at the highest point? My simulation result is true or false? and what is a unit of delay?

This is mean e2e delay

Hi Elnaz,

Do you declare throughput in inetmanet/src/application?  I declare how to implement in rar file. Hope this helpful for you.

hi 

i work on this sample too. i don't know your answer. but i have question a bout this sample.

why end to end delay and Throughput( that it between app and net module) just measure for host1 ,2?

when I run star net, Throughput for another hosts are 0 !

I truly appreciate your help

Are your sample original? If you dont edit this sample, i guest, packet was sent from host 0, host 1 receive and send packet to host 2, therefore end2end delay and throughtput measure for host1 and host 2.

Hi 

Thank you very much for your help

yes, my sample is original.

surry I am new user of omnet and realy beginner.

I have another question:

my traffic is   **.host[0].app.trafDest="host[1]"

                    **.host[1].app.trafDest="host[2]"

if my numHost=6

I want to another hosts send  Data to host[1]"PAN coordinator"

how can I do it! 

my opinion is: 

I have to type these:

 **.host[*].app.trafDest="host[1]"

**.host[*].**.mac.isRecvGTS = true # receive GTS

Is it right?

Thank you in advance

Best Regards

**.host[1].app.trafDest="host[2]"

**.host[*].app.trafDest="host[1]"

 

First the specific, later the generic

 

If you set this

**.host[*].app.trafDest="host[1]"

**.host[1].app.trafDest="host[2]"

 

All nodes, including the host[1] will send the traffic to the node host[1]

Hi all,

did you find any solution to your problem??
