Energy-aware blockchain for multiple autonomous underwater vehicles cooperative operation
Xinbin Li, Yingzheng Guo, Lei Yan, Xianglin Xu · 2021
Multiple autonomous underwater vehicles (AUVs) have been widely used in various of missions in underwater environment, such as tracking and searching. However, multi-AUV search targets in local area face to security challenges still. To solve this issue, in this paper, we propose a secure, energy-saving multi-AUV cooperative operation scheme blockchain-based. In order to enhance the security, control commands and state information are packaged into blocks by encryption algorithm of blockchain. Considering energy-efficient of the entire network, we present an improved Raft consensus algorithm based on energy model, named E-Raft. Balancing the excess of leader’s energy consumption by setting thresholds. Our proposed approach not only guarantees the security of data, but extends working time of the network and the energy utilization. Simulation results justify the effectiveness of the scheme.
