Abstract: Refering to the application requirement that node number is not mass and real time communication is not very important, it put forward a high effective and low energy consume requirement of wireless sensor network MAC protocol based on the IEEE 802. 15. 4 standard. hhe software mainly makes use of interrupt control and function call-back.The physical layer is provided with the function of wireless transceiver management to support low energy consume.hhe MAC layer adopts slotted CSMA-CA to carry out the node to access channel. The nodes include common nodes and coordinators. Common nodes adopt poll and sleep mechanism, implement in-direct data transmit with the coordinator.The experiment result shows that the application system achieves the target of low energy consume and high effective.
Key words: Wireless sensor network, Protocol, 802. 15. 4, Low energy consume, High effective
