B. the server is sent to the aggregation node starts aggregation node order；
C. the aggregation node, which receives to start in institute step b, orders and feeds back startup confirmation；
D. feedback starts after confirmation in the server receiving step c, send configuration aggregation node order；
E. configuration order and feedback configuration confirmation in the aggregation node receiving step d；
F. the server is received in step e after configure-ack, and upload command is started to aggregation node issue；
G. the aggregation node receives feedback startup upload confirmation after upload command in step f, and is passed to the server transport
The data and status information of sensor node.
Further, the step g is specially：
The sensing data frame collected is sent to the aggregation node, the convergence by the sensor node by wireless network
The sensing data frame received is pre-stored by node；After the startup of server upload command is received, feedback, which is uploaded, to be confirmed
And pre-stored sensing data frame is organized into the frame for meeting TCP/IP communication protocol specification, serviced and sent by WiFi communication
To the server.
Beneficial effect
Whole system is based on emerging double-deck, twocouese a radio network technique：1）One wide area stratum reticulare, it is by one
Server and many aggregation nodes composition；2）One sensor network layer, including an aggregation node and many sensor sections
Point.Compared with traditional scheme, the program is by way of aggregation node and removal residential gateway, by wide area network and sensor network
Network combines together so that wide area network and sensor network are more closely combined togather.Via node number can be reduced, is reduced
Cost, accelerates network design, helps to realize between heterogeneous system and takes over seamlessly.Aggregation node acts not only as sensor network layer
In only coordinator, while also serving as an independent sensor node in wide area stratum reticulare.
