| 摘要: |
| 传统防盗技术存在诸多弊端,无法满足防盗需求.无线传感器网络的常规防盗方式也有着无可避免的局限性.根据无线通信的阴影效应提出一种基于无线传感器网络的防盗技术,通过接收信号强度的变化判断盗贼的入侵.建立了防盗系统的框架,并对其中的关键技术进行研究.通过定义防盗系统的图模型,将代理分配问题抽象为顶点分边问题,并提出B-EPV算法求优化解.设计Blade算法求解k-众数集问题,以获得稳定的RSSI值范围.搭建了真实实验环境,验证了防盗系统的性能.实验结果表明,系统具有较低的误报率和漏报率. |

| Abstract: |
| There are shortcomings in traditional anti-theft technology which can not satisfy a user’s demand.The common ways of anti-theft are limited in wireless sensor networks.On the topic of the shadowing effect in wireless communication,this paper introduces a anti-theft technology based on wireless sensor networks.System can check intrusion by analyzing received signal strengths.This paper establishes a framework of anti-theft system and studies the key technologies.By defining the graph model in anti-theft system,the agent distribution problem is abstracted into edges partitioned by vertices problem.B-EPV algorithm is proposed for obtaining the optimal solution.Blade algorithm is designed for solving k-mode set problem to get steady status of link.This paper constructs experimental environment with real motes and verifies the performance of the system.The result shows low false positives and false negatives in the system. |
