Message delivery is difficult due to the frequent link disconnections in VANETs. In our previous research we proposed a carry, store and forward-based method aiming at high delivery ratio and low message overhead. Each car periodically exchanges information on its current position and scheduled driving route in the car navigation system with neighbor cars. Based on the exchanged information, each car forwards its messages to the neighbor car that will approach the closest to the destination. In this paper, we enhance this previous technique by combining the idea of multi point relays (MPR) in OLSR protocol, and propose a new message delivery method.
