The movement of nodes has a great influence on the performance of protocols in mobile ad hoc networks.Mobility model is used to describe the movement of nodes, react the mobile characteristics really.In real circumstances, mobile devices are usually attached to humans ,so the movement of such devices has the movement features of human movement.Through analyzing the cluster evolution features of real GPS trace, this paper proposed a cluster evolution based mobility model(CEMM),which reflects the human cluster dynamics features in real urban environment.We also compared the mobility features of CEMM with the classical human mobility features model SMOOTH, the results show CEMM works better in reflecting the cluster dynamics features.
