中文摘要:为预测异质传感网(HWSNs)的可用性能,提出一种面向恶意程序传播的HWSNs稳态可用度评估方法。在考虑异质传感节点实际状态基础上,增加状态D(死亡)扩展经典SIR传染病模型得到SIRD模型以描述节点因能量耗尽、物理损坏或恶意程序攻击导致功能丧失的情况。使用Markov链描述节点各状态之间的动态转换过程,分析得到状态转换矩阵和各状态变化的动力学方程。推理得到一个异质传感节点的稳态可用度计算公式,再依次推理得到星形和簇形HWSNs稳态可用度计算公式。实验分析了IDS检测率和误报率对异质传感节点稳态可用度的影响,验证了所提出方法的有效性。
外文摘要:To predict available performance of Heterogeneous Wireless Sensor Networks ( HWSNs ), we propose a method to evaluate steady-state availability of HWSNs under malware infection. Based on actual states of an hetero- geneous sensor node, we extend the traditional epidemic-model SIR to SIRD by adding state D (Dead) to describe the case that a node is dysfunctional due to energy consumption, physical damage, or malware attacks. We next illus- trate state transitions among different states with a Markov chain, analyze and attain the state transition matrix and dynamical equations of all states. Moreover,we compute a node's steady-state availability, and deduce steady-state availability equations for star and cluster HWSNs, respectively. Experiments analyze influences produced by IDS' detection rate and false alarm rate on a node's steady-state availability, and verify the proposed method's efficiency.
