Vehicles find it challenging to select the target uplink node among the roadside units (RSU) put in VANETs due to the RSU coverage, traffic intensity, and other sophisticated and dynamic affecting factors. In this study, a new adaptive vehicle clustering method is proposed that attempts to reduce the power consumption of automobiles. It dynamically distributes the computational assets of every virtual machine within the automobile. The <i>mimosa pudica</i> clustering optimization algorithm (MPCOA) is used to identify the ideal clustering number to reduce the overall energy consumption of the cars, and the clustering head is chosen based on the direction the vehicles are going, their weighted mobility, and their entropy. A cluster head (CH) oversees all intercluster and intracluster communication. Some factors to gauge the effectiveness of a network include the load on every CH, the lifespan of the cluster, and the overall number of clusters in the network. The new cluster is well suited for this type of huge data, in which they are separated into similarity, variations, and neighborhoods as different types of VANET features along with their combinational groups. Using a test bed and numerous simulations, the suggested system efficacy is assessed.

As one of the key technologies, MIMO signal detection ensures the reliability of communication systems and achieves high throughput transmission. In this paper, to find a high-performance and low-complexity detection algorithm, a hybrid detection algorithm is proposed based on the K-best detection algorithm. The hybrid algorithm employs the minimum mean square error (MMSE) linear detection algorithm combined with sorted QR decomposition (SQRD) for preprocessing, followed by signal detection using the K-best detection algorithm. Compared with the traditional K-best detection algorithm, the proposed method shows significant performance improvement. To address the computational complexity issue caused by the fixed K value in each layer of the hybrid detection algorithm, an adaptive threshold algorithm is introduced to select an appropriate K value for each layer, significantly reducing the algorithm's complexity. On the hardware implementation level, not only is the overall algorithm architecture optimized but a lookup table (LUT) based sorting algorithm is also proposed to address the sorting delay issue in the hybrid detection algorithm.

To address this issue, we propose the use of the artificial rabbit optimization (ARO) algorithm as an optimization strategy. The ARO algorithm dynamically adjusts and searches for weights and thresholds during the initialization and training of BP neural networks to find the global optimal solution. This approach efficiently explores the weight space and enhances the BP neural network's performance in ultrasonic localization tasks. Experiments have confirmed that the hybrid ARO-BP localization algorithm performs well in matching predicted trajectories with actual positions, especially in a 3D localization scenario constructed by six base stations. The algorithm produces excellent results in both line-of-sight (LOS) and non–line-of-sight (NLOS) environments, which are typical indoor settings. The ARO-BP neural network effectively reduces the average localization error and ensures high-precision localization under various transmission conditions and obstacle effects. In NLOS conditions, the positioning accuracy is improved by 16.05% with four tags and 10.92% with six tags, resulting in an average error reduction of 8.02 cm. The ARO-BP algorithm enhances positioning accuracy by 13.99% with four tags and 21.76% with six tags, resulting in an average error reduction of 12.01 cm. In conclusion, ARO-BP significantly improves the accuracy of ultrasonic localization in both LOS and NLOS indoor environments with reflections and diffractions.
