Abstract
Autonomous Vehicle Platoon (AVP) is the most promising solution to various problems in the Intelligent Transportation System. However, how to effectively manage the join and leaving vehicles, and ensure the profit of the platoon leader remains an open problem. In this paper, we propose a dynamic AVP management protocol by implementing Ethereum. Vehicle who wants to join and leave the platoon has to communicate with the platoon leader, and all messages will be related to the corresponding transactions regulated by the smart contract. Considering the cost efficiency of the AVP system, a hybrid chain model is constructed. The public chain provides with certification records. All platoon message communication records will be stored on the privacy chain and will be upload to the public chain as platoon operation incident record. The evaluation result and security analysis indicate that our proposed scheme is practical for AVP scenario in terms of both efficient and secure.
