Abstract
Due to the challenges of low bandwidth, high latency, and high communication energy costs in acoustic channel communication, data collection in underwater acoustic sensor networks (UASNs) remains severely restricted. The assistance of multiple autonomous underwater vehicles (AUVs) in data collection brings the advantages of low latency and energy-efficient balance. However, existing AUV-assisted data collection schemes preplan paths and assume data transmission from all nodes, which is inefficient in information delay-sensitive monitoring scenarios. Furthermore, most schemes do not consider the influence of ocean currents when studying path planning. To solve these problems, this article proposes a joint optimization scheme for multi-AUV cooperative data collection based on the Stackelberg game, where the task allocation and path planning problems are formulated as the leader and follower of the Stackelberg game, respectively. At the leader level, a sequential game-based algorithm is proposed, dynamically allocating cluster heads that require data transmission to different AUVs. At the follower level, the influence of ocean currents is considered, and an improved backtracking method is employed to plan the optimal path for each AUV. Experimental results show that the proposed method significantly improves network performance when compared with other representative underwater data collection methods.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
