摘要：Efficient data delivery in vehicular sensor networks
is still a challenging research issue. Position-based routing
protocols have been proven to be more suitable for dynamic
vehicular networks or large-scale mobile sensor networks than
traditional ad hoc routing protocols. However, position-based
routing assumes that intermediate nodes can always be found
to set up an end-to-end connection between the source and the
destination; otherwise, it suffers from network partitions which
are very common in vehicular networks and leads to poor
performances. This paper addresses data delivery challenge in
the possible intermittently connected vehicular sensor networks
by combining position-based forwarding strategy with store-carry-forward routing scheme from delay tolerant networks. The
proposed routing method makes use of vehicle driving direction
to determine whether holding or forwarding the packet. Experimental
results show that the proposed mechanism outperforms
existing position-based solutions in terms of packet delivery ratio.
