This paper proposed a routing protocol integrating both the characteristic of the flooding-based protocol and forwarding-based protocol. The basic idea of our protocol is to let message be forwarded to the nodes moving toward or closer to destination. When nodes contact with each other, our approach will utilize the path of the node, node's moving direction and velocity to estimate the probability to reach the destination of the message. At the same time, we exploit network coding to transmit coded block instead of message fragment in order to avoid sending redundant replication. In this way, data transport is more reliable and more robust to packet losses or delays. From the results of simulation, we could see that our protocol has enhanced performance, especially for the bandwidth consumption compared to other protocols.
