【Abstract】 With advancement in wireless communications and electronics,the sensor networks can be used for various application areas ,such as health ,military and so on. The MAC protocol is an important technology for the creation of the network infrastructure. It achieves tow goals in the sensor network ,the first is the establishment of the links for data transfer; the second is to fairly and efficiently share communication resources between sensor nodes. This paper specifies the design and the classification of MAC protocol in sensor network,and explains recent protocols of each type in detail.更多还原
