Embodiment Construction
[0031] Most of the time, most people tend to drive vehicles on a relatively fixed route in their daily life, such as going to work, school, and the market, so most vehicles have predefined daily trajectory constants. Basically the present invention innovatively proposes a hybrid event-centric and entity-centric reputation system.
[0032] like figure 1 As shown, the vehicles that participate in the entire life cycle of traffic events from occurrence, propagation, and termination are divided into three categories: the vehicle that directly senses the occurrence of a traffic event and sends the event first is called the event reporter; The vehicles receiving messages within the hop range are called event observers; the rest of the relay nodes participating in event propagation are called event participants. The core idea of the framework is to make full use of distributed roadside units (RSUs) to realize an entity-centric reputation building mechanism, supplemented by an even...
