Resumo(s)
—In a vehicular platoon, a lead vehicle that is
responsible for managing the platoon’s moving directions
and velocity periodically disseminates control commands to
following vehicles based on vehicle-to-vehicle communications.
However, reducing command dissemination latency with multiple
vehicles while ensuring successful message delivery to
the tail vehicle is challenging. We propose a new linear dynamic
programming algorithm using backward induction and
interchange arguments to minimize the dissemination latency
of the vehicles. Furthermore, a closed form of dissemination
latency in vehicular platoon is obtained by utilizing Markov
chain with M/M/1 queuing model. Simulation results confirm
that the proposed dynamic programming algorithm improves
the dissemination rate by at least 50.9%, compared to similar
algorithms in the literature. Moreover, it also approximates
the best performance with the maximum gap of up to 0.2
second in terms of latency.
