中文摘要: 本课题提出了新的基于无线传感器网络的绿色通信技术的研究工作。在该工作中,我们首先在理论上研究了无线传感器网络中超低占空比的同步机制,并在此基础上建立无线节点的同步模型。然后在同步模型的理论基础上研究和设计超低功耗的通信协议。我们采用跨层协议设计的思路,将MAC功能和路由功能嵌入在网络的同步机制上,力求最大限度降低通信功耗。最后我们采用环境能源采集的方式为整个网络提供能量,整个网络不需要电池供电。该项工作为超低功耗的无线传感器网络提供了理论模型,并在解决物联网能源问题上有实际的应用价值。

英文摘要: We proposed a research work on the WSNs based green communication. In this work, we will first theoretically analyze the ultra low duty cycle synchronization issue in the wireless sensor network. Based on our theoretical analysis, we will establish a synchronization model. Second, we will design a new ultra low power communication protocol which includes both the MAC functionality and the routing functionality on the basis of the established synchronization model. In order to reduce the power consumption of the communication protocol; we adopt the cross-layer design approach. Finally, we proposed a new energy harvesting method to power the whole network instead of using the battery. We believe our work will lay the theoretical foundation for the ultra low power communication in wireless sensor network. Also it provide a practical green communication method for the applications of the internet of things.
