%X This paper proposed a channel reservation based MAC protocol. It was improved on S-MAC protocol. In the data transmission process, it sent and received the information of channel reservation through competition. Every node distributed channel according to need. Then activated each node according to the reserved time slot and transmitted the data by TDMA. The CR-MAC protocol can effectively decrease the idle listening and crosstalk interference of the nodes and reduce the energy consumption and transmission delay. It has some practical significance for development of wireless sensor networks.
