SENSOR NETWORK AND METHOD FOR COMPOSITION THEREOF

摘要

A sensor network and a constitution thereof for preventing the generation of overload in a specific area are provided to maintain a state of network and make uniform load of a sensor node without overload in a specific area. A first sensor node performs communication by supplying internal power. A second sensor node performs communications by supplying external power. A gateway(100) receives data from the second sensor node and transmits the data to a communication server. According to the second sensor node is the overload occurrence possibility and is arranged in much power source used amount location. The data are received from the first sensor node and transmits to the gateway.
