The road conditions during the winter especially in mountain areas are one of the significant safety subjects for the residences and the tourists. However, there are still many places where the wireless networks such as 3G and LTE are hard to connect in the mountain areas, and it is also difficult to keep continuous data transmissions during the nodes are moving. Therefore, this paper proposes the Delay Tolerant Networks (DTN) with Adaptive Array Antenna (AAA) Control systems for the V2V networks. In the proposed systems, the vehicles equip the AAA control systems with IEEE802.11a/b/g in the proposed system, and the radio direction is controlled by the pattern recognitions from camera images with Kalman filter algorithm. The prototype system and the experiments are introduced in the paper, and the results are discussed for the effectiveness of the proposed systems and the future studies.
