摘要 该文通过数学模型分析网络处于饱和状态时,终端采用DCF的基本方式和RTS/CTS方式发送一个固定长度的数据包所需要消耗的能量.进而,得到数据包载荷长度在给定的区间上服从一定的分布条件下,RTS门限和终端发送一个数据包所需消耗能量的平均值之间的关系。研究发现,存在一个使终端发送的平均能耗最小的最佳RTS门限,给出了最佳RTS门限的求解方法.计算机仿真结果很好地验证了理论分析的正确性。 In saturated IEEE 802.11 WLAN, the energy consumption in transmission per frame through basic mode and RTS/CTS mode is analyzed through mathematical model. The relation of RTS threshold and average energy consumption per frame is produced in the assumption that the frame payload's length is distributed in a given interval. Further analysis shows there is an optimum RTS threshold that can minimize the average energy consumption. The method of calculating optimum RTS threshold is also presented. All theoretical analysis is validated through computer simulation.
