Mobility modeling in wireless networks: categorization, smooth movement, and border effects

摘要: The movement pattern of mobile users plays an important role in performance analysis wireless computer and communication networks. In this paper, we first give overview classification mobility models used for simulation-based studies. Then, present enhanced random model, which makes the trace stations more realistic than common approaches mobility. Our concept is based on processes speed direction control new values are correlated to previous ones. Upon a change event, target chosen, acceleration set achieve speed. principles changes similar. Finally, discuss strategies stations' border behavior (i.e., what happens when nodes move out simulation area) show effects certain behaviors spatial user distribution.
