However, previous works consider neighbors' opinions being just normal and anomalous, and do not consider the uncertainty of neighbors to the data of the node. In this paper, we propose SLAD (subjective logic based anomaly detection) framework. It redefines opinion deriving from subjective logic theory which takes the uncertainty into account. Furthermore, it fuses the opinions of neighbors to get the quantitative anomaly score of the data. Simulation results show that SLAD framework improves the performance of anomaly detection compared with previous works. <\/jats:p>","DOI":"10.1155\/2012\/482191","type":"journal-article","created":{"date-parts":[[2012,1,19]],"date-time":"2012-01-19T21:04:16Z","timestamp":1327007056000},"page":"482191","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Subjective Logic-Based Anomaly Detection Framework in Wireless Sensor Networks"],"prefix":"10.1177","volume":"8","author":[{"given":"Jinhui","family":"Yuan","sequence":"first","affiliation":[{"name":"Key Laboratory of Data Engineering and Knowledge Engineering, MOE, Beijing 100872, China"},{"name":"School of Information, Renmin University of China, Beijing 100872, China"},{"name":"Institute of Electronic Technology, Information Engineering University, Zhengzhou 450004, China"}]},{"given":"Hongwei","family":"Zhou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Data Engineering and Knowledge Engineering, MOE, Beijing 100872, China"},{"name":"School of Information, Renmin University of China, Beijing 100872, China"},{"name":"Institute of Electronic Technology, Information Engineering University, Zhengzhou 450004, China"}]},{"given":"Hong","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Data Engineering and Knowledge Engineering, MOE, Beijing 100872, China"},{"name":"School of Information, Renmin University of China, Beijing 100872, China"}]}],"member":"179","published-online":{"date-parts":[[2012,1,19]]},"reference":[{"first-page":"271","volume-title":"Proceedings of the 5th Annual ACM\/IEEE International Conference on Mobile Computing and Networking","author":"Kahn J.
