摘　　要：无线传感器网络(Wireless Sensor Networks,WSNs)由于其部署环境的特殊性,极易受到恶意攻击或发生故障,故对其可生存性量化评估的研究逐渐受到关注.本文提出了基于连续时间马尔可夫链的WSNs可生存性量化评估模型.该模型给出了遭受恶意节点攻击的WSNs状态转换过程,通过该模型实现了对网络的可靠性(考虑独立失效与相关失效)、可用性及生存性的定量分析.利用仿真实验对模型进行了验证.实验结果表明,所提出的模型能够有效评估WSNs的可生存性,并且可为今后设计高生存性的WSNs提供依据.Wireless Sensor Networks(WSNs)are susceptible to malicious attacks or failures due to the particularity of the deployment environment.Therefore,survivability assessment for WSNs has gradually attracted attention.This paper proposed a survivability assessment model of WSNs based on continuous-time Markov chains.The state transition process of WSNs under the attack of malicious nodes in this model was given.Quantitative analysis of the reliability(considering independent failures and related failures),availability and survivability of WSNs were realized by this model.Then,the model was verified by simulation experiments.The experimental results show that the proposed model can effectively evaluate the survivability of WSNs and provide a basis for the design of highly survivable WSNs.
