Design and Implement of Wireless Sensor Network Medium Access Control Protocol
Yunjian Tang · 2009
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.The 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.The 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.
