面向恶意程序传播的异质WSNs稳态可用度评估
Steady-State Availability Evaluation for Heterogeneous WSNs under Malware Infection
摘要
Abstract
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 heterogeneous 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 illustrate 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.关键词
