摘要

LEACH协议有效地解决了无线传感器网络(WSN)能耗性问题

但是在安全性方面存在较大的隐患。因此提出了一种改进LEACH协议安全性能的LEACH-S机制

采用接收信号强度值(RSSI)的Sybil攻击入侵检测策略

通过设定合理的阈值启动该机制

即只有在判定可能遭遇Sybil攻击时才启动

实验表明该机制能以较少的能耗代价来有效检测出Sybil攻击。

Abstract

Low energy adaptive clustering hierarchy（LEACH） could effectively reduce energy consumption of wireless sensor network（WSN）.However

a novel security mechanism was proposed based on LEACH protocol called LEACH-S in order to improve the security performance of WSN.The mechanism adopted a received signal strength indicator（RSSI） based policy for Sybil attack detection in WSN

and a reasonable threshold was chosen to initialize Sybil attack detection strategy in which case attack may occur with high possibility.The simulation results show that the mechanism can detect Sybil attack effectively at the cost of low energy consumption.
