摘要
无线传感器可以集成能量收集设备进行长期自主的电池能量管理,现有研究都是基于电池状态完全已知的,但准确估计这种信息较难实现.研究主要针对部分状态信息进行分析,定义了一个性能指标函数,比较不同传输策略的优劣.考虑能量收集过程,分析能量独立到达最优化的具体方法.结合能量传输信道增益信息,为不同情境设计相应的传输策略.通过综合研究策略的性能指标及仿真分析,得出基于无线传感网络收集设备最佳传输策略.
Wireless sensors can be integrated with energy collection devices for Long-term Autonomous Battery Energy Management.The existing research is based on the state of the battery is fully known,but accurate estimation of this information is difficult to achieve.In this paper,a performance index function is defined to compare the advantages and disadvantages of different transmission strategies.Considering the process of energy collection,the specific method of energy independent reaching optimization is analyzed.Combining the information of energy transmission channel gain,the corresponding transmission strategies are designed for different scenarios.Based on the analysis of the performance index and simulation of the strategy,the optimal transmission strategy of the Wireless sensor network is obtained.
