In this paper, we develop a new Medium Access Control (MAC) protocol that based on hybrid FDMA/TDMA technology with three-jump network. This protocol combines the advantages of both FDMA and TDMA. The communication of cluster heads is based on FDMA technology which can decrease the crosstalk between different frequency and the cluster heads can identify each other easily; the inter cluster communication is based on TDMA technology to achieve basic time synchronization. Then the time synchronization of the network was obtained. At the same time, the three-jump network increased the range of communication system and reduced the power. The protocol adopts cluster head rotation mechanism. TH-MAC has the advantages of low crosstalk between frequency, low power and low latency. It applies to the large-scale collection of data and information about industry and agriculture and worth of application.
