In existing anomaly detection approaches, sensor node often turns to neighbors to further determine whether the data is normal\r\nwhile the node itself cannot decide. However, previous works consider neighbors� opinions being just normal and anomalous,\r\nand do not consider the uncertainty of neighbors to the data of the node. In this paper, we propose SLAD (subjective logic based\r\nanomaly detection) framework. It redefines opinion deriving from subjective logic theory which takes the uncertainty into account.\r\nFurthermore, it fuses the opinions of neighbors to get the quantitative anomaly score of the data. Simulation results show that\r\nSLAD framework improves the performance of anomaly detection compared with previous works.
