Facing the contradiction between malware intention and continuous-time Markov chain (CTMC) randomness, we introduce a strategic game that can predict malware infection in order to model a successful infection as a CTMC state transition. Next, we devise a novel measure to compute the Mean Time to Failure (MTTF) of a sensor node, which represents the reliability of a sensor node continuously performing tasks such as sensing, transmitting, and fusing data. Since clustered WSNs can be regarded as parallel-serial-parallel systems, the reliability of a clustered WSN can be evaluated via classical reliability theory. Numerical results show the influence of parameters such as the true positive rate and the false positive rate on a sensor node\u2019s MTTF. Furthermore, we validate the method of reliability evaluation for a clustered WSN according to the number of sensor nodes in a cluster, the number of clusters in a route, and the number of routes in the WSN.<\/jats:p>","DOI":"10.3390\/s16060855","type":"journal-article","created":{"date-parts":[[2016,6,10]],"date-time":"2016-06-10T07:37:41Z","timestamp":1465544261000},"page":"855","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Reliability Evaluation for Clustered WSNs under Malware Propagation"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-5379","authenticated-orcid":false,"given":"Shigen","family":"Shen","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Shaoxing University, Shaoxing 312000, China"},{"name":"College of Mathematics, Physics and Information Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Longjun","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Shaoxing University, Shaoxing 312000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianhua","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Mathematics, Physics and Information Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Champion","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, The Ohio State University, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shui","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Information Technology, Deakin University, Burwood 3125, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiying","family":"Cao","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Donghua University, Shanghai 201620, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1860","DOI":"10.1109\/COMST.2014.2320073","article-title":"Survey on the characterization and classification of wireless sensor network applications","volume":"16","author":"Borges","year":"2014","journal-title":"IEEE Commun.
