针对无线传感器网络的能量问题,分析了传感节点的能耗特点,引入了能量消耗模型,探讨了能耗模型的极限情况,指出无线传感器网络中全网最大能耗取决于每比特数据的采集、接收和发送的能量、单跳的信道容量和网络的规模。基于该模型从硬件和软件两方面提出了节能策略,并进行了仿真验证。为无线传感器网络的节能设计提供理论支持。
In view of the energy problem of wireless sensor network, the energy consumption characteristics of sensor nodes are analyzed, the energy consumption model is introduced, the limit of energy consumption model is discussed, and the maximum energy consumption of the whole network in wireless sensor network depends on the acquisition of each bit of data , Received and transmitted energy, single-hop channel capacity, and network size. Based on the model, the energy-saving strategy is proposed from hardware and software, and the simulation is carried out. Provide theoretical support for the energy-saving design of wireless sensor networks.
