Presto[12]提出一种分割数据流的路由优化方案，通过粒度的大小将

Presto [12] proposed a routing optimization scheme for splitting data streams, which distributes traffic to parallel paths through the granularity of the granularity to achieve load balancing. However, the optimal flow distribution on the parallel path of the above scheme requires comprehensive consideration of the global flow status, which is difficult to achieve the best decision in VANET.

Presto proposed a routing optimization scheme for segmenting data streams, allocating traffic to parallel paths by the size of granularity, in order to achieve load balancing. However, the optimal traffic allocation on the parallel path of the above scheme requires a comprehensive consideration of the global traffic state, which makes it difficult to achieve the best decision in VANET.

Presto [12] proposed a routing optimization scheme to divide the data flow, which distributes the flow to the parallel path through the size of granularity to achieve the purpose of load balancing. However, the optimal traffic allocation of the above scheme on the parallel path needs to consider the global traffic state comprehensively, which is difficult to achieve the optimal decision in VANET.<br>
