无线传感器网络内可疑节点的分析研究

Analysis and Study of Suspicious Nodes in Wireless Sensor Networks

在无线传感器网络中,传感器节点对信号采集传递的可靠性决定系统结果的准确程度,而对于应用于不同领域的WSNs而言,节点损坏、信息传递过程受到攻击的情况时有发生,为了保证结果的准确,及时准确的判断节点的工作情况至关重要;进而对传感器节点进行分析,介绍几种可疑节点判断方式,同时结合WSNs在母婴监控系统中的应用,通过信号强度及信号呈现的规律检测可疑节点的方案在母婴监控系统中的实用性,分析了母婴监控系统中是如何利用可疑节点来达到监控的效果。

In wireless sensor networks （WSNs）,the reliability of the signal acquisition transfer affects the accuracy of the system result,and for applied in different areas of the WSNs,the node can be damaged,the situation of the information transfer process is under attack,in order to guarantee the accuracy of the results,timely and accurate judgment nodes working condition is very important.Based on sensor node analysis,the paper introduces the suspicious nodes judging ways,at the same time combining the application of the WSNs on maternal and infant security system,By the law of the signal strength and signal presented to detect suspicious nodes solution in maternal and infant security system of practical,and analyzes the maternal and infant security system how to use the suspicious nodes to achieve the result of monitoring.
