Zhexin Xu proposed a sophisticated adaptive multi-channel MAC protocol, to significantly improve the utilization and fairness of the time slot allocation scheme needed for VANET. The proposed protocol is based on the concept of SD-TDMA. The rationale is that collision users can participate in the time slot allocation system again as soon as possible after the start of the SCHI. Compared to existing methods, it is demonstrated that our approach can more efficiently and dynamically allocate time slots based on the detection topology, while simultaneously reducing transmission collisions through a user detection procedure. The simulation results were shown to be in agreement with the mathematical derivations. In future work, other multiple access technologies will be employed to improve spectrum utilization[8].

By comparing the angles of neighboring nodes, the neighbor node with the minimum angle will be selected as the next hop in the time complexity analysis, compared to GPSR, MM-GPSR does not add time complexity, the proposed MM-GPSR has better performance than GPSR [9]LAISEN NIE et al. proposed that the spatio-temporal characteristics of the traffic matrix be taken into account in anomaly detection and a CNN-based anomaly. Convolutional and hierarchical subsampling layers deeply extract multifractal and low-rank features for traffic estimation network. Furthermore, a threshold-based method is referred to in our approach for further anomaly detection. By analyzing the proposed approach applied to the real network dataset, the simulated result states that the proposed method can identify anomalies in normal traffic flows exactly for VANET[10]. Zhihao Ding proposed an improved routing protocol in VANETs by modifying the data forwarding procedure of the existing GPSR routing protocol. The strong point of our proposed routing protocol is that we reduce the delay and strengthen the reliability of the routes. They optimized the next hop selection strategy of the well-known GPSR routing protocol using mobility and MAC delay estimation. Our routing protocol method is based on vehicular electronic devices which can provide a large amount of vehicular information. They added mobility information (speed and direction) and MAC delay estimation into the next hop selection strategy to make the route more reliable and reduce the delay.[11]Remember: this is just an example.
