The invention discloses a wireless intelligent sensor network protocol (ATZGB-SleepTree) with ultra-low power consumption. The protocol includes a physical layer, an MAC (media access control) layer, a link layer, a network layer and an application layer according to an OSI (open system interconnection) reference model. A traditional wireless sensor protocol and even an existing ZigBee protocol are quite difficult to meet the requirements of low power consumption, low cost, high fault tolerance and the like of a wireless sensor, and under the circumstance, the ATZGB-SleepTree protocol arises at the historic moment. The ATZGB-SleepTree constructs a wireless network which is low in cost and power consumption, high in sensitivity, reliability and real-time control and transmission, highly flexible in work pattern and configuration, automated in link management, capable of achieving AES (advanced encryption standard) data encryption, supportive to multiple bands and multiple wireless rates and capable of achieving synchronous sleep and synchronous wake-up of all nodes of the whole network, routing fault-tolerance and automatic recovery and is used for substituting for traditional wireless and cable network transmission modes.
