- Abstract:
- Major consideration dimensions for the physical layer design of wireless sensor network(WSN)nodes is analyzed by comparing different wireless communication approaches, diverse mature standards, important radio frequency(RF)parameters and various microcontroller unit(MCU)solutions.An implementation of the WSN node is presented with experimental results and a novel “one processor working at two frequencies” energy saving strategy.The lifetime estimation issue is analyzed with consideration to the periodical listen required by common WSN media access control(MAC)algorithms.It can be concluded that the startup time of the RF which determines the best sleep time ratio and the shortest backoff slot time of MAC, the RF frequency and modulation methods which determinate the RX and TX current, and the overall energy consumption of the dual frequency MCU SOC(system on chip)are the most essential factors for the WSN node physical layer design.
- 比较和分析了无线传感器网络节点物理层设计的各种无线通信技术、现有的成熟标准、重要的射频参数以及不同的处理器方案, 对节点物理层设计的各个主要方面进行了较为全面的研究.介绍了无线传感器网络节点的一种实现, 给出了相关的测试数据以及一种“单处理器双工作频率”的新节能策略.分析了符合传感器网络MAC算法中节点周期性侦听要求的节点寿命估算问题.指出无线传感器网络节点物理层设计的关键考虑因素为:RF启动时间(决定MAC 协议可以实现的最佳节点睡眠时间比例和最小的退避时间颗粒)、RF载波频率和调制方式(决定射频收发功耗)以及处理器工作在2个频率的片上系统的总体功耗.
