The space net divides the solution space of combinatorial problems into multiple regions, and each region stores landscape information. This information can guide the algorithm to find the better solution compare with ACO.
Traffic Violations Generation: Data Augmentation of Video Generation Based on Diffusion Model
– A system generates irregular-behavior videos in a steady quality, which can be recognized by most of the object detecting systems;
– Unlike other video generation models, this system does not require high-quality inputs;
– This system is able to run with restricted computing and training resources.
Reliability-considered Multi-platoon’s Groupcasting using the Resource Sharing Method
In the context of 5G platoon communications, the Platoon Leader Vehicle (PLV) employs groupcasting to transmit control messages to Platoon Member Vehicles (PMVs). Due to the restricted transmission power for groupcasting, it may need to pick one PMV as the Platoon Relay Vehicle (PRV) to be responsible for re-groupcasting PLV’s messages. To optimize the use of limited spectrum resources, resource sharing is implemented to enhance spectrum efficiency within the platoon. This study proposes a resource allocation method, which is called Resource Sharing for Platoon Groupcasting (RSPG), for platoon’s groupcasting based on transmission reliability. RSPG utilizes the tripartite matching to assign a subchannel to either a PLV or PRV that shares the assigned subchannel with the corresponding individual entity (IE), which does not belong to any platoon. The simulation results shown that the proposed method has the better performance in terms of IEs’ QoS satisfaction rate, the allocated subchannels for platoons, and spectral efficiency.
