Abstract
Various ad-hoc routing protocols have been proposed for wireless networks with dense distribution of wireless nodes. For support of multihop transmission in sparse wireless networks, some DTN (delay-tolerant network) routing have been proposed. However, it is difficult to get better tradeoff between communication overhead and reachability of data messages in DTN routing. This paper proposes a novel DTN routing protocol with help of satellite navigation system mounted on vehicles for vehicular ad-hoc networks (VANETs). By transmission of data messages along a driving route detected by the navigation system and recovery from the deviation due to next-hop detection failure, the proposed routing achieves high reachability though no copies of data messages are transmitted.
