摘要
The present invention relates to a system that can increase the network survival time by reducing the amount of data transmission in the sensor network, interworking with the sensor network that collects data from at least one sensor node, and transmits the monitoring task through a wired or wireless communication network including the Internet. And a remote management server that integrates and manages the collected monitoring data and reports it to an administrator, receives a monitoring task from the remote management server, manages the sensor node, and collects data that has been merged from the sensor node and manages the remote management. It includes a sink node that forwards to the server. The sensor node obtains an average value and a standard deviation of data detected by the one or more sensor nodes, and compares the data with previous data to determine whether to transmit the data to the sink node. . According to the present invention, it is possible to reduce the amount of packet transmission of the entire network by transmitting the detected data only at the time of the data change, thereby making it possible to efficiently use energy in a sensor network with severe energy constraint.;Sensor network, data merging, routing protocol
