摘要
为了保护电路元件、维持系统持续高效的工作状态,系统利用稳压电路对CC2530和节点优化电路进行稳压。节点优化电路将网络节点的干扰排除,以供CC2530进行定位操作。系统将最佳安全节点定位算法输入到网络节点,CC2530利用该算法对最佳安全节点进行精准定位。软件选用统计模拟法作为最佳安全节点定位算法,并给出其计算流程图和概率函数。经实验验证,所设计的系统能够较强地对入侵节点进行验证,并拥有较小的最佳安全节点定位误差。
In order to protect the circuit components and keep the efficient working state of the system,the voltage stabiliz?ing circuit is used in the system to ensure voltage stability of CC2530 and node optimization circuit. The node optimization cir?cuit is adopted to exclude the interference of network nodes to support the positioning operation of CC2530. The best security node localization algorithm is input to the network node by the system. The algorithm is utilized by CC2530 to pinpoint the best security node. The statistical simulation method is selected by the software as a best security node localization algorithm,whose calculation flow chart and probability function are given in this paper. The experimental verification result indicates the system can verify the intrusion node well,and have small positioning error for the best security node.
