The invention discloses a wireless caching strategy based on a bundling algorithm and a multi-round two-way auction theory and provides a file data resource distribution algorithm based on the bundling algorithm and the multi-round two-layer auction theory in a wireless random network. When a file provider begins to provide the copyright of a video file, the own files are firstly bundled to a filepackage and the initial price is put forward, and according to Zipf distribution, popularities of the files are added to be the total popularity of the file package, and the total popularity is usedas a weight parameter of the file package. According to requirements of mobile users in the coverage range of a WiFi node, the price offered and requirements on the file package are put forward, an intermediate party calculates each price offered density value of the two parties according to price asked of the two parties and the requirements on the files, match is carried out according to an order from high to low of a seller and from low to high of a buyer, after ending of one round, a user failing in match can change the requirements and participates in the next round, the auction is endeduntil the two parties are stabilized, a Nash equilibrium point is achieved, the video file is cached to the corresponding WiFi node, and delay minimization is realized.
