A Design of Awakening Strategy for Wireless Sensor Network

Based on a wireless sensor network with fixed network structure applied to grain storage monitoring system, the thesis designs an effective awakening strategy in the case of the non-synchronous network nodes. It enhances one-time-wake-up-rate of nodes with low power consumption, which overcomes the disadvantage of the universal awakening strategy. Experiment results show that one-time-wake-up-rate of nodes is higher than 95% and two batteries of AA 1.5V can drive node 5 years continuously.
