Survivability evaluating method applicable to attacked wireless sensing network

Abstract

The invention discloses a survivability evaluating method applicable to an attacked wireless sensing network. In order to overcome the defect that the existing evaluating method is not applicable to the attacked wireless sensing network, the technical scheme adopted by the invention comprises the steps that the state of a sensing point in the whole life cycle is determined; the nonzero and random game theory is utilized for building a game model between a malicious attacker and the wireless sensing network, and the optimal attach strategy of the malicious attacker is calculated; a state transition matrix based on a Markov process is constructed, and the stability probability of the Markov process is calculated; the average fault-free time of the sensing node, the reliability degree of the sensing node, the reliability degree of clusters and the routing reliability are calculated; the reliability degree of the whole attached wireless sensing network is calculated; and the lifetime of the whole attached wireless sensing network is calculated. The survivability evaluating method has the advantages that the survivability evaluating method is applicable to the attached wireless sensing network, specific numerical values are utilized for describing the network condition, the quantitative analysis is realized, and the evaluation is accurate and reliable.
