For complex battlefield environment is lack of stable end-to-end communication path between user terminals, a Delay Tolerant Network (DTN) clustering routing algorithm based on Vehicular Ad Hoc NETwork (VANET) communication terminals and motion information named CVCTM (Cluster based on VANET Communication Terminals and Motion information) was proposed. Firstly, the clustering algorithm based on cluster head election was studied; secondly, the routing algorithm for intra-cluster source vehicle was studied based on hop count, relay mode and geographical location information. Then, the routing algorithm for inter-cluster source vehicle was realized by introducing waiting time, threshold of retransmission times and downstream cluster heads. Finally, the optimal way of communicating with upper headquarter was chosen by VANET communication terminals. The ONE simulation results show that the message delivery ratio of CVCTM increased nearly 5%, the network overhead of it decreased nearly 10%, the recombination times of cluster structure decreased nearly 25% in the comparison with AODV (Ad Hoc On-demand Distance Vector routing); the message delivery ratio of CVCTM increased nearly 10%, the network overhead of it decreased nearly 25%, the recombination times of cluster structure decreased nearly 40% in the comparison with CBRP (Cluster Based Routing Protocal) algorithm and DSR (Dynamic Source Routing) protocal. CVCTM can effectively reduce network overhead and recombination times of cluster structure and increase message delivery ratio.
