Effect of mobility on the critical transmitting range for connectivity in wireless ad hoc networks

The effect of mobility on the critical transmitting range in wireless ad hoc networks is discussed in this paper. A new parameter, pause probability P_pause, which is the function of the minimum velocity V_min, the maximum velocity V_max and the pause time t_pause of random waypoint (RWP) mobility model, is defined. Simulation results show that the effect of RWP parameter on the critical transmitting range is determined by P_pause that is, if P_pause smaller than 0.5, the critical transmitting range of mobile network is about 10 percent larger than that of stationary one, else it equals that of stationary network approximately. If the values of t_pause, V_min and V_max are given, their effect on the critical transmitting range is determined since P_pause is the function of them.
