PHBDR (Position History-Based Dead Reckoning)

Hybrid approach

Update packets only contain the object’s most recent position

Remote hosts estimate the instantaneous velocity and acceleration by averaging the position samples.

Reducing bandwidth

Improving prediction accuracy

(as “snapshot” velocities and accelerations can be misleading.)
