<p>The present invention relates to a method for transmitting data using a wireless sensor node forming a wireless sensor network including multiple hops, the method comprising the steps of: collecting meter reading data by each node; receiving metering data obtained from a lower node in 1 hop units; comparing a data total capacity obtained by adding metering data received from the lower node to a data capacity of the received metering data of each node itself with a pre-assigned critical capacity; and when the data total capacity is greater than the critical capacity, directly transmitting the metering data received from the lower node to a concentrator on the basis of an IP address and transmitting the metering data of each node itself to a upper node located in a 1 hop interval on the basis of a MAC address. The present invention mixedly uses a MAC address based communication scheme and an IP address based communication scheme, thereby raising communication efficiency in a low-rate wireless network interval and solving a traffic problem.</p> |
