In this scheme, whenever the observing vehicle receives continuous beacons

from a reporting vehicle V

r

, it calculates the current expected position of the report-

ing vehicle based on its last received information from the beacons of the same

reporting vehicle V

r

at time t − Δt. Here, beacons are assumed to carry information

such as current position, speed, and steering angle of the reporting vehicle. Based

on the calculation of the current expected position of the reporting vehicle V

r

, the

vehicle V

o

calculates the expected zone for the V

r

. Also, V

o

estimates the observed

zone of the vehicle V

r

based on the current beacon information, received from V

r

at

time t. If the two z ...
