“…If these two types of data has not been received, the gateway node detecte repeatedly until it receives data. If the gateway node receives the host computer data after checking is correct, use broadcast sending to all nodes [5]; If the gateway node receives the data of each node in the network, and then after a check sent to the host using the serial port, thus completing the entire task of Gateway node. They are the RSSI signal strength request, that the received signal strength value is sent to the positioning node; reference node request configuration, that the position coordinate of the reference node is configured according to the data signal sent by the gateway node, and then data is written in Flash; Reference nodes request configuration, that reference node itself coordinates configuration sent to the gateway node [6]; collecting RSSI value, that many times to collect signal intensity values received between the reference node and positioning node.…”
