چکیده
In order to solve effectively the problem of evaluating the wireless sensor network fault tolerance, this paper presents an evaluation index of the topological tolerance for failure node according to the ability of the topology keeping network connect and cover in case of existing failure nodes and establishes a quantitative evaluation model of topology fault tolerance according to semi-Markov process. Through analyzing quantitatively the changes of topological state causing by failure nodes and the state of topology responding to failure nodes, the evaluation index of the topological fault tolerance has been obtained and then the effectiveness of the topological fault tolerance quantitative evaluation model proposed has been verified through experiment and comparison.
