入侵检测是无线传感器网络安全研究的一个重要方面。针对现有的入侵检测方案大多只考虑保护单一的网络设施，很少将整个WSN网络看作一个整体来进行入侵检测的不足，提出一种面向边界入侵检测的节点部署方案。首先将整个监测区域看作一个整体，然后基于逆高斯分布对节点进行部署，靠近边界的区域被部署更多数量的传感器节点，最后为了保证整个网络的连通和覆盖，通过将整个区域划分为多个轮，从理论上分析了在每轮中所需部署传感器节点的最少数目。仿真实验结果表明，该方案能够有效地实现入侵检测，在入侵距离和入侵所触发的传感器节点数目方面都要优于高斯部署和均匀部署方案。

Intrusion detection is an important aspect of the research of network safety in wireless sensor networks.Aiming at the disadvan-tages of existing intrusion detection schemes that they only consider the protection of single network infrastructure but rarely deem the WSN as a whole in intrusion detection,this paper presents a node deployment scheme for boundary intrusion detection.Firstly,it deems the entire monitoring area as a whole,and then deploys the nodes based on reverse Gaussian distribution,the larger number of sensor nodes is deployed to the area closing the boundary,finally,in order to ensure the connectivity and coverage over the entire network,the area is divided onto multiple rounds,the required minimum number of the deployed sensor nodes in each round is analysed theoretically.Simulation experimental results show that this scheme can effectively realise intrusion detection,and is superior to Gaussian deployment and uniform deployment sce-narios in terms of intrusion distance and the number of sensor nodes by invasion triggered.
