We present a new routing protocol in this paper to enhance junction-based routing for
vehicle-to-vehicle (V2V) vehicular ad-hoc networks (VANETs). Employing effective
routing table learning and maintenance, the new protocol is able to accomplish better
transmission stability and lower transmission cost. In practice, the mechanism of routing
table learning will help a vehicle establish its own static path information by which to
locate suitable relay vehicles in a more efficient way, and the practice of routing table
maintenance may substantially reduce the probability of finding no suitable relay vehicles,
to avoid unnecessary packet discarding. Extended simulation is conducted to evaluate the
performance of our new protocol and related routing protocols. The results exhibit that
our protocol performs constantly better than others in terms of packet delivery ratios,
packet drop ratios and average delay time. It ensures more efficient transmission without
additional control overhead in highly mobile V2V VANETs.
