Abstract:

无线传感器网络(Wireless Sensor Networks, WSN)节点是物联网构成的关键部分，其中电池的使用寿命是制约其发展的重要因素。脉冲MPPSK调制比连续MPPSK调制拥有更高的能量利用率，非常适合作为WSN节点的通信方式。本文通过对基于改进型脉冲MPPSK调制的WSN节点进行建模，推导出了每单位比特能耗的公式，并按照节点间距离进行了仿真验证。
The nodes of Wireless Sensor Networks (WSN) are key part of the Internet of things. The life of the battery is an important factor which restricts its development. Pulse MPPSK modulation, which is suitable for the communication mode of WSN nodes, has a higher energy utilization rate than con-tinuous MPPSK modulation. In this paper, we model the WSN node based on the improved pulse MPPSK modulation, and derive the formula of the energy consumption per bit. At the end of this paper, the simulation results are carried out according to the distance between the nodes.
