摘要
The article introduces Wireless Sensor Network technology and the demand of the hospital environment monitoring, the hospital environment monitoring system is realized by the application of Wireless Sensor Network technology, the hospital environment monitoring device is designed and as sensor nodes in the system. Through the analysis of the main factors what influence the energy consumption of WSN and the existing energy-saving technology, this paper proposes a reliable data transmission algorithm (DPMCA) which is based on energy balance, the algorithm is an effective combination of the Dynamic Power Management technology with the Clustering Algorithm. Experiment and simulation results show that this algorithm realizes energy balance and prolongs the lifecycle of the 2-3 times and prevents the sensor node data packet loss caused by premature death, thus it improves the data transmission reliability of the monitoring system of the hospital environment.
