The invention discloses a
wireless sensor
network clustering routing method based on hexagonal regional division. The method comprises the following steps that six line segments (base lines) from a Sink node of a sensing area center divide a sensing area into six sector areas, wherein the included angle between every two adjacent base lines is 60 degrees; the sensing area is densely paved by hexagonal grids, a sensing node acquires
longitude and
latitude information by sensing self position information and calculates the distance between the position thereof and the closest
base line, so that whether the hexagonal area where the sensing node is located is on the
base line or not is judged, and if the hexagonal area is on the
base line, after a clustering head is selected, the node that is selected to be the clustering head is changed into a gathering point; clustering head selection and data are transmitted by a multi-hop
relay between the clustering head and the gathering point; the flow of the
wireless sensing network from start to
data acquisition is divided into a clustering head selecting and intra-cluster single-hop transmission process, and inter-cluster routing between the clustering head and the gathering point. The problem of too
high energy consumption caused by too long transmission distance between clustering heads is solved, and the
energy consumption during
data acquisition of the network is greatly reduced.
