Ye-fei Tian · 2017
In this paper, we study the method of wireless sensor network based on energy-saving wireless sensor network, and put forward the comparison criteria of wireless transmission network single transmission system and performance of collaborative transmission system based on space-time block code.Aiming at the characteristics of wireless sensor network energy limitation, and the threshold level of the optimal transmit power of the cooperative transmission system is calculated.The simulation results show that the threshold level can minimize the total transmission power of the wireless sensor network under the condition of satisfying the certain probability of the system.
