A Star Low-power Wireless Sensor Network Design and Analysis

In order to solve data collection and transmission problem of smart home, a low-power wireless data acquisition star topologic network was designed, and a star topologic network communication protocol was given. Using queuing theory, the establishment of M/M/1 model analysis was carried out. By analyzing the time prediction of adjustment period, sensor capacity and power calculation of stationary period, power system disturbances of added sensor and other problems, a detailed analysis of the power consumption of the system was carried out, and calculation methods were given. The experiment proved that the system normal working hours exceeds 5 months, which meets low power consumption, the real-time data acquisition and accuracy requirements demand.
