I want to synchronize the initial clock of multiple smartphone devices (Android-based) for real-time VoIP communication. Basically, a MANET has been formed and I want to synchronize the clocks up to
5ms difference in MANET.
So far using Ultrasonic chirp, I have been able to synchronize the initial clock with up to
100ms of difference.
What approaches should I follow to get the desired difference?
I have read many research papers I cant use
NTP for time-sync and I came to know about
PTP about which I am unable to find any algorithm to implement in MANETS.
