Wireless sensor network is generally composed by plenty of micro-sensors that arranged on designated area. The supervision of these sensor nodes is used to finish the collecting, disposing and uploading of vast information. However, the security of wireless sensor network has many problems, since the sensor node itself exists plenty of limitation. Aiming at the problems of smart wireless sensor network security as well as the analysis of wireless sensor network node easy been attacked, wiretapped and forged without safeguard, this paper put forward a security policy of smart wireless sensor network. Simple and useful intrusion detection policy was realized from a series of improvement of LEACH protocol of low-energy self-adaptation cluster routing protocol.
