This paper proposes a new method for access control and mitigation of interfering noise in time synchronization environments. First, a formal definition is given regarding the impact interference noise has on the clock skew and clock offset of each node. The degree of node interference behavior is estimated dynamically from the perspective of time-stamp changes caused by the interference noise. Secondly, a general access control model is proposed to resist invasion of noise interference. A prediction model is constructed using the Bayesian method for calculating the reliability of neighbor node behavior in the proposed model. Interference noise, which attacks the time synchronization, is regarded as the key factor for probability estimation of the reliability. The result of the calculations determines whether it is necessary to initiate synchronization filtering. Finally, a division of trust levels with bilinear definition is employed to lower interference noise and improve the quality of interference detection. Experimental results show that this model has advantages in system overhead, energy consumption and testing errors, compared to its counterparts. When the disturbance intensity of a WSN increases, the proposed optimized algorithm converges faster with a lower network communication load.<\/jats:p>","DOI":"10.3390\/s18072107","type":"journal-article","created":{"date-parts":[[2018,7,2]],"date-time":"2018-07-02T10:56:52Z","timestamp":1530529012000},"page":"2107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Access Control Model Based on Time Synchronization Trust in Wireless Sensor Networks"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7502-3651","authenticated-orcid":false,"given":"Zhaobin","family":"Liu","sequence":"first","affiliation":[{"name":"School of Computer Engineering, Suzhou Vocational University, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiang","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Software, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenzhi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Suzhou Vocational University, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4960-174X","authenticated-orcid":false,"given":"Victor S.","family":"Sheng","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Central Arkansas, Conway, AR 72035, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Suzhou Vocational University, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Suzhou Vocational University, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.adhoc.2017.07.003","article-title":"An adaptive stabilizing imposter detection scheme for distributed mobile wireless sensor networks","volume":"65","author":"Alrashed","year":"2017","journal-title":"Ad Hoc Netw."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Jesus, G., Casimiro, G., and Oliveira, A.
