| 英文摘要 | In order to solve the problem of limited storage capacity of server in edge computing, this paper proposed a data cooperative cache strategy based on game theory. The strategy divided the edge computing environment into a plurality of regions in accordance with the coverage of the base station, each region cooperating with an adjacent region to cache data resources. In each region, the strategy calculated the cache value of each data block to the local area and the adjacent area, made the cache decision according to the cache value of the resources to be cache, and minimized the delay of the user to obtain the data resources. The simulation results show that the average acquisition delay of data resources in the proposed cache strategy is 36.55% lower than that in the existing non-cooperative cache strategy, which effectively reduces the average acquisition delay of the data resources. |
