无线传感网是当前物联网技术研究的热点,无线传感网中如何对能耗进行控制以延长网络的生存时间又成为其中最受关注的问题.为了实现能耗的有效控制,通过对能耗模型的研究和建立,研究提出了一种基于多信道无线传感网的节能机制.它基于非坚持CSMA协议,是通过对非坚持CSMA协议中退避过程的控制和对物理层调制阶数的控制来达到控制能耗目的.同时结合多信道无线传感网中可使用多个信道的特点,建立的节能机制加入可用信道数量来共同分析和处理.最后仿真试验验证了文中提出的机制具有提升能耗效率的效果.
Wireless sensor network is the hotspot of the current IOT technology research, how to control the energy consumption in the wireless sensor network to prolong the survival time of the network becomes one of the most concerned issues.In order to achieve effective control of energy consumption, Consumption model, this paper proposes a power saving mechanism based on multi-channel wireless sensor network.It is based on the non-adherence to the CSMA protocol by controlling the back-off process in the CSMA protocol and adjusting the modulation order of the physical layer Control to achieve the purpose of controlling energy consumption.At the same time, combined with the characteristics of multiple channels that can be used in multi-channel wireless sensor networks, the established energy-saving mechanism can be analyzed and dealt with by adding the number of available channels.Finally, the simulation results show that the mechanism proposed in this paper has a promotion The effect of energy efficiency.
