The security has always been the eternal topic in the field of Information technology. As a major part of Internet of Things (IoT), the perception layer acts critical roles from cognizing and sensing the ambient world to implement control instructions. So, the security of perception layer is very important. In this paper, a simplified attack detection method is proposed through study of typical routing protocol in the perception layer of IoT. This method, based on attack model, could analyze the security leak of routing protocol in perception layer to a certain extent.
