对无线传感器网络进行有效的组网设计和部署是决定其生存寿命、降低网络成本的首要和关键步骤,对此,在引入非线性电池能耗模型评估节点能耗的基础上,结合网络非均匀部署策略、时分多址技术以及节能优化的正交频移键控数据调制技术,提出了一种基于节点轮流工作机制的新颖组网方法.仿真结果表明,该组网方法不仅可以减少网络部署所需的节点数,降低部署成本,同时还可提高能量利用效率,延长网络的工作寿命.
The effective network design and deployment of wireless sensor networks is the primary and key step to determine their life expectancy and reduce the network cost. Based on the introduction of non-linear battery energy consumption model to evaluate the energy consumption of nodes, Deployment strategy, time division multiple access technology and energy-saving optimized orthogonal frequency shift keying data modulation technology, a novel networking method based on node rotation mechanism is proposed.The simulation results show that this method can not only reduce the network deployment The number of required nodes reduces the deployment cost, and at the same time improves the energy utilization efficiency and prolongs the working life of the network.
