摘要/Abstract

摘要： 立足无线入侵检测系统这一应用背景,针对系统无法预知目标主机网卡发射功率信息这一问题,尝试在Shadowing模型基础上进行变换,利用接收信号强度差来进行最小二乘定位计算,从而消除对发射功率参数的依赖。通过对无线入侵检测系统定位模块的设计、实现与测试,验证了此方法的可行性,实现了室内环境Room-level级三维定位。试验数据显示, 在综合考虑系统定位精度与成本的情况下,保证空间中一点能够被8个检测节点覆盖到时,系统的精度和成本综合最优。

关键词: 三维定位,无线入侵检测系统,接收信号强度指示,遮蔽模型,最小二乘

Abstract: This paper was based on the application background of wireless intrusion detection system,which wants to locate target host,but can not predict transmitted power of target’s wireless network card．By using received signal strength indication difference for the least square calculation,which is based on the transformation of Shadowing model,the method can eliminate the dependence of transmitted power parameter．By means of the design,realization and test of the positioning module for wireless intrusion detection system,the feasibility of the method was verified．Finally,an indoor three-dimensional positioning module with Room-level precision was achieved in WIDS．Experiment data shows that precision and cost of the system are integrally optimal as a space point can be covered by 8detection nodes.

Key words: Three-dimensional positioning,Wireless intrusion detection system,RSSI,Shadowing model,Least square
