摘要
文章首先提出一种传感器网络目标定位系统的系统模型,然后利用PtolemyⅡ建模仿真平台完成该传感器网络目标定位系统的系统级行为描述,并根据系统级建模方法学对该目标定位系统进行建模与仿真,分析了传感器网络目标定位系统的诸多影响因素。测试结果表明:传感器网络目标定位系统对于传感器节点的功耗及信息时间同步窗口具有敏感性,符合传感器网络目标定位系统应用特性,验证了Ptolemy嵌入式系统级设计方法学对于指导传感器网络系统设计的正确性和可行性。
This paper firstly provide a system model of a sensor networks objects orientation system,then it completes system-level behavior description of the sensor networks object orientation system with ptolemy Ⅱ modeling and simulation platform, and simullate the object orientation system according to the methodology of the system-level modeling, and analyse a good many impact factors.The test results shows that sensor networks object orientation system is sensitivity to the power waste and information time synchronous windows of sensor nodes,tally with the application characteristic of the sensor networks object orientation system,and validates the correctness and feasibility of the ptolemy Ⅱ embedded system-level design methodology to guide sensor networks system design.
