In this paper, we designed and analyzed a MAC protocol that is adaptive to traffic and improved energy efficiency in a WSN(wireless sensor network) environment.Due to the development of ubiquitous computing environment, Wireless sensor network technology is being applied in various fields and fusion research is being underway.The wireless sensor network allows wireless sensor nodes to communicate with each other in a distributed network environment and collects data of the necessary area as a connected structure also, it is a structure that connects collected data to a wired network through a sink.First of all, it is very important to manage the energy more efficiently than the QoS requirement because the wireless sensor nodes maintain the life cycle using the battery.In consideration of these issues, the IEEE 802.15.4 MAC protocol is studying traffic adaptive MAC protocol and standardization work emphasizing reliability and efficiency in a wireless sensor network environment.However, the response speed of the sensor node is lowered as the energy efficiency of the wireless sensor node is reduced.Therefore, in this paper, we analyze the MAC protocol of synchronous and hybrid methods, and design the MAC protocol with improved energy efficiency of the whole network and the safety and the efficiency are mathematically proved and analyzed through experiments.
