摘　　要：文章分析了当前无线传感器网络中基于调度的MAC层协议的特点,针对新的应用领域中对数据实时性和全局性要求较高的特点,提出了一种新的基于TDMA的MAC层协议,通过充分利用空闲时隙,允许有较高数据传输需求的节点使用其他节点的空闲时隙传输数据,使得在满足实时性要求的同时能够反映监测区域的全局特征。通过在CC2430硬件平台上对该协议进行测试,实验数据表明该MAC层协议不仅可以降低数据的时延,而且也能够反映数据的全局性特点。It analyzes the characteristics of current scheduling based MAC layer protocol in wireless sensor networks （WSN）, and propo- ses a new TDMA based MAC layer protocol with good performance of real-time and overall situation for new application field. By mak- ing full use of time slots,the protocol allows the node with higher demands for transmission to use the idle slots to transmit the data, this can reflect the overall situation while satisfy the real-time requirements. Subsequently, implement and test the protocol on CC2430 hard- ware platform. Finally, the experimental results indicate that the new TDMA based MAC protocol can not only reduces the delay of data, but also reflects the overall situation of data.
