It analyzes the characteristics of current scheduling based MAC layer protocol in wireless sensor networks(WSN),and proposes a new TDMA based MAC layer protocol with good performance of real-time and overall situation for new application field.By making 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 hardware 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.
