Abstract: On a ATmega based selfdesigned hardware platform， the international standard protocol for IEEE 802154 was designed and implemented. In the design and implementation of the standard protocol， the idea of a finite state machine was adopted， and the standard protocol node was divided into a number of states. In addition， triggering conditions could cause transition between state and state. For IEEE 802154 protocol， the trigger condition is to receive a different frame and upper commands. Using the idea of a finite state machine complex logic processing could be separated， and the protocol could be more scalability. In order to extend the life of the nodes and improve the flexibility of the protocol， a method based on adaptive CAP and CFP regulation and management were designed and implemented. The practical application results showed that the method was effective to extend the node life and suitable for certain upper application.This method has certain significance for the IEEE 802154 protocol of applied research. The standard implementation of the field of research and development has an important role.

Key words: IEEE 802154 protocol, standardization, finite state machine design, adaptive regulation, management of CAP and CFP
