How to estimate latency of computation and networking (e.g., given a bandwith of X and a distance Y, which is the time required to send Z packtes?) in CloudSim / iFogSim / EdgeCloudSim?
My suggestion for you:
1.http://www.cloudbus.org/cloudsim/
2.http://www.buyya.com/papers/iFogSim-Tut.pdf
3. https://github.com/CagataySonmez/EdgeCloudSim

Good luck
The general theory is
Total Latency = Transmission Time + Propagation Delay
So if the packet size is P, then
Transmission Time = Z * P / X
Propagation Delay = Y /c where c is the speed of light in the medium
Latency = Z*P/X + Y/c
I don't know how to estimate the latency for a given distance. Maybe there are some papers presenting that. Usually we just set a latency value for simulations and the time to transfer files is computed based on the available bandwidth, given latency and file size.
CloudSim Plus has some fix related to file transfer from a Storage Area Network (SAN), such as:
https://github.com/manoelcampos/cloudsim-plus/issues/138
https://github.com/manoelcampos/cloudsim-plus/issues/137
https://github.com/manoelcampos/cloudsim-plus/issues/132
I has a lot of other issues fixed for the network module and also supports joint network and power-aware simulations.
