摘要： 提出一种基于攻击检测的安全LEACH协议S-LEACH。该协议根据LEACH协议的特点，采用在簇头选举和数据传输阶段在数据包尾部捎带检测参数信息的方法，通过节点能量和接收信号强度值，综合判断传感器网路中的HELLO flood攻击和Sybil攻击；同时针对簇头节点和簇内节点的攻击，分别设计了2种检测方法，提高了检测精度。最后在NS-2软件中建立了WSN真实网络空间的Jakes信道模型，利用该模型验证了S-LEACH协议的安全性。

Abstract: In this paper we propose a security LEACH (S-LAECH) protocol based on attack detection. According to the characteristics of LEACH routing protocol, this method keeps test parameters at the end of package in the periods of head node selection and data transmission. Thus, judgment of HELLO flood attack and Sybil attack of sensor network is jointly made according to the node power and received signal strength. At the same time, aiming at attacks of cluster head nodes and cluster member nodes, two detecting methods are used to improve accuracy. Jakes channel model in a WSN real network space is established with NS-2 software. Using this model, security of S-LAECH is verified.
