The problem is that Casper model can only adapt to the situation in which users are moving slowly.When users are in high-speed movement,Casper model can not construct good anonymous area and cause poor service quality.In order to solve this problem,this paper proposes a location privacy protection method based on V-grid model.It introduces V-grid model which takes in the parameter of users speed,updates users’ locations before constructing anonymous areas and meets kinds of users’ privacy need.Experimental results show that V-grid model has better applicability and achieves higher service quality than Casper model.
