中文摘要：

对sinkhole攻击进行了研究，提出了基于多点监测与回复信息的攻击检测方法。利用基站和节点间数据包的传输与确认，结合邻节点的监视机制对节点收发的数据包统计分析，检测sinkhole攻击。这种方法避免了复杂的加密算法与身份认证，与多路径安全机制相比有着更高的可靠性。对安全概率进行了理论分析，并进一步通过仿真实验对方法进行了验证。

英文摘要：

To study sinkhole attack,a light-weight method based on multipoint monitoring and acknowledge information is proposed.Through the transmission and acknowledgement of packets between base station and sensor nodes,combined with multipoint monitoring,the author makes the statistical analysis of the packets sent and received to detect the sinkhole attack.The method avoids from complicated encryption and identity certification proposed in some other methods.By comparison,the reliability of the method is relatively higher than that of multipath security mechanism .The author also examines the security probability of the method using both theoretical analysis and simulations.
