中文摘要：
目前无线传感器网络中DoS攻击的问题越来越受到关注,传统IP网络中运用的溯源方法由于额外的资源开销、需求过重等因素并不直接适用于无线传感器网络。介绍了几种适用于的无线传感器网络环境的溯源方法,分析了这些方法实现溯源功能的原理,同时就在使用这些溯源方法后传感器节点产生的额外的计算开销、存储空间开销、通信开销和溯源操作的收敛时间以及溯源方法在多节点协同攻击下的健壮性几个方面对这些方法做了性能分析和比较。
英文摘要：
DoS attacks in wireless sensor networks are now drawing more and more attention.Traditional traceback methods in IP networks are not suitable for sensor networks due to heavy extra resource overhead requirements.In this paper,mainly describe several traceback methods which are suited to be used in sensor networks.Analyze how these methods work and make a qualitative comparison from the following aspects： extra computation,storage and communication overhead of sensor nodes after traceback methods are put into use,convergence time traceback operation takes and the robustness of the methods under colluding attacks.
