Dynamic Cooperative MAC Optimization in RSU-Enhanced VANETs: A Distributed Approach

no code implementations14 Feb 2024 Zhou Zhang, Saman Atapattu, Yizhu Wang, Sumei Sun, Kandeepan Sithamparanathan

We propose the RSU Probing and Cooperative Access (RPCA) strategy, a two-stage approach based on dynamic inter-vehicle distances from the RSU.

Learning county from pixels: Corn yield prediction with attention-weighted multiple instance learning

no code implementations2 Dec 2023 Xiaoyu Wang, Yuchi Ma, Qunying Huang, Zhengwei Yang, Zhou Zhang

Furthermore, through an in-depth study of the relationship between mixed pixels and attention, it is verified that our approach can capture critical feature information while filtering out noise from mixed pixels.
