Detection(APTAD)is proposed to col.ect integrated IoT data by recruiting Mobil. Edge Users(MEUs).(a)An intel.igent unsupervised l.arning approach is used to identify anomal.us data from the col.ected data by MEUs and hel. to identify anomal.us nodes.(b)Recruit MEUs to trace back and propose a series of trust cal.ul.tion methods to determine the trust of nodes.(c)The l.st,the number of active detection packets and detection paths are designed,so as to accuratel. identify the trust of nodes in IoT at the minimum cost of the network.A l.rge number of experimental.resul.s show that the recruiting cost and average anomal. detection time are reduced by 6.5 times and 34.33%respectivel.,whil. the accuracy of trust identification is improved by 20%.
