METHOD FOR ENHANCING ENERGY CONSUMPTION EFFICIENCY OF WIRELESS SENSOR NETWORK

摘要

The present invention relates to a method for improving energy consumption efficiency of a wireless sensor network, and more particularly, to a method for improving energy consumption efficiency of a wireless sensor network using a situation recognition control method in a data collection pointer.;The method of improving energy consumption efficiency of the wireless sensor network of the present invention includes the steps of: (a) detecting occurrence of an event at a sensor node; (b) the sensor node transmitting event data on the generated event to a data collection device; (c) identifying an event in a sensor node area in the data collection device; (d) transmitting the event data transmission prohibition message to the sensor nodes by the data collection device, and (e) prohibiting the transmission of event data of the sensor nodes that have received the event data transmission prohibition message. have.;Accordingly, the present invention utilizes the computing resources of the data collection device to improve the energy consumption efficiency of the sensor nodes in the wireless sensor network, thereby reducing unnecessary data transmission with the sensor nodes in a manner of delivering a message to the sensor nodes. It has the effect of improving the energy consumption efficiency of the node.
