【摘要】 无线传感器网络由于自身网络特点,网络层路由协议易于受到各种攻击。本文分析选择性转发攻击的实现原理,提出一种基于网络拓扑的选择性转发攻击检测方法。该检测方法通过统计方式分析网络拓扑结构和节点的发送行为,利用统计数据检测节点丢包率,从而确定攻击节点。检测网络与通信网络分离开,考虑多条路由因素,具有较高的可靠性。更多还原

【Abstract】 Due to the characteristics of WSN(Wireless Sensor Network),route protocols of network layer are vulnerable to various attacks.This paper presents a detection scheme based on network topology in selective forwarding attack by analyzing the principles in attacks.The assay analysis statistical methods of network topology and node sending behaviour,thus make use of statistical data to calculate detection node packet loss rate,and finally determine the attack nodes.This scheme is more reliable due to separation of communication and detection and adding multiply router factor.更多还原
