Wireless LAN channel in the open state, link status is unstable, bandwidth resources are limited, in terms of performance and quality of service there is a big gap. How to make better use of its limited resources is becoming increasingly important. MAC layer is mainly to provide a fair, reliable, efficient scheduling mechanism to allocate radio channel resources; performance is directly related to the performance of the wireless channel utilization and the entire network. As IoT are widely used in industry, agriculture, national defense and people's life, which requires the network with state energy-saving monitoring, fault alarm, and other intelligent recognition, automatic measurement and control functions. This paper presents the discrete time three-dimensional probability CSMA protocol with function of energy-saving monitoring which can change the value of P making the system throughput is more adaptive to the load. The paper uses the average cycle analysis method to analysis the protocol model, getting the precision expression of system throughput.
