摘要
无线传感器节点的软件架构直接影响整个网络的运行效率和寿命,以分模块、层次化、虚拟多任务为指导思想设计的节点软件平台,完全达到了传感器网络的能效性、自组织、稳定性等要求,实验者可以在该软件平台上添加试验代码,进行MAC协议、路由、安全算法等网络试验;节点硬件选高档8位AVR单片机ATmega128L为CPU,结合外围传感器和2.4GHz无线收发模块CC2420,在该硬件平台基础上设计了节点的软件架构,为加速WSN的商业化应用提出了一种新的、简洁高效的技术模式。
The software architecture of node impacts on the efficiency and lifetime of WSN. We use modules, level and multi--tasking to design software platform and fully achieve the energy efficiency, self--organization and stability. Experimenter can easily plug and pull out function code on the platform, and test it. Node hardware select top--grade 8 bit AVR microprocessor ATmega128L as CPU, and select special sensors and 2.4GHz wireless communication module CC2420 as peripheral component. Based on this hardware platform, we designed the software architecture of node, further provided a new, simple, and efficient technical model for commercialization application of WSN.
