Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] see figure 2 , in this embodiment, temperature sensor nodes and video sensor nodes are used to represent simple media nodes and complex media nodes respectively, and the implementation method of the heterogeneous sensor network system supporting the wake-up mechanism of the present invention is described: the temperature sensor nodes are in the monitoring state for a long time, and the real-time sensing Measure the external environment, sense whether there are abnormal emergencies in the outside world, and regularly transmit the sensed temperature data to the data aggregation node in a multi-hop transmission mode. Each temperature sensor node is provided with rules for analyzing and judging the sensed temperature data. Once the temperature value exceeds a...
