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/sub pause/, which is the function of the minimum velocity V/sub min/, the maximum velocity V/sub max/ and the pause time t/sub 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/sub pause/ that is, if P/sub 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/sub pause/, V/sub min/ and V/sub max/ are given, their effect on the critical transmitting range is determined since P/sub pause/ is the function of them.
