Wireless mobile node can reduce self access data latency and save bandwidth for whole network by caching data,aiming at this characteristic,this paper improves revenue function of Distributed Greedy Algorithm(DGA).It divides the data access frequency into local access frequency and other node access frequency,and researches the application scenes of different weights.NS2 simulation results show that the efficiency of data caching can be enhanced through reasonably selecting weight in different scenes.
