In this paper, we investigate the performance of two-dimensional cellular networks in consideration of the mobility of mobile nodes through the simulation. We assume that each mobile node moves in accordance with the random way point method in the two-dimensional cellular network. The speed of mobile nodes are given by three different probability distributions, that is, truncated exponential, uniform, and reverse truncated distributions. The moving angle of mobile nodes is given by the uniform distribution. The performance is measured by blocking probability of handover call, mean handover times, and mean channel occupation time. From the simulation studies, we conclude that 1)the effect of the change of moving angle on the performance is very small. 2)concerning the speed distribution of the mobile nodes, the dominant factor on the performance is the low speed of mobile nodes.
