Judge the cluster belonging to oneself, the sensor node in same square virtual grid can mutually obtain information, form neighbours' section
Point list, aggregation node include stand-by period threshold value to each sensor node broadcasts sub-clustering message, wherein sub-clustering message, each
Sensor node in square virtual grid calculates certainly according to the following formula after the sub-clustering message of aggregation node transmission is received
The state value of body, and the other sensors node into communication range is the state value that neighbor node broadcasts oneself：
In formula, WbRepresent sensor node b state value, QbFor sensor node b current remaining, Qb0Sensor
Node b primary power,For the central point o of square virtual grid belonging to sensor node b to itsbDistance, Z tables
Show the length of side of square virtual grid, Db-jRepresent sensor node b to the distance of its j-th of neighbor node, nbRepresent sensor
Node b neighbor node number；
(2) sensor node receives the state value of other sensors node transmission in stand-by period threshold value, if receiving
When one state value is more than the state value of itself, the sensor node is the election contest for abandoning leader cluster node, serves as rank and file's section
Point；If the state value received in stand-by period threshold value is smaller than the state value of itself, the sensor node turns into cluster head
Node, and broadcast and notify to neighbor node.
Based on the Clustering Model of last embodiment, the present embodiment further provides the clustering routing plan of sensor node
Slightly, the strategy is using square virtual grid as a cluster unit, and the election contest for the comparison progress leader cluster node for passing through state value,
Uniform sub-clustering is advantageously implemented, and is caused similar, closer to affiliated square virtual grid center, surplus with each neighbor node
There is sensor node more than complementary energy bigger probability to turn into leader cluster node, and the clustering route protocol can reduce network total energy
Amount consumption, balance sensor node energy consumption, so as to which the communication of mountain flood monitoring and warning system can be saved on the whole
Cost, improve the reliability of mountain flood monitoring and warning system work.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
