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/l 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, 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.
