A relay node and multiple sensor nodes, wherein sensor node is specifically located at each critical positions of arch dam, four relaying sections
Point is identical as the distance between aggregation node, and can be with aggregation node direct communication；Sensor node is according to current remaining
The communication distance for adjusting itself, when with the distance apart from nearest relay node be less than the communication distance when, sensor node with
, apart from nearest relay node direct communication, otherwise sensor node selects next-hop in its neighbor node, next with this for this
Row direct communication is jumped into, the neighbor node is the other sensors node in sensor node communication range；Relaying
The vibration data that node receiving sensor node is sent, and received vibration data is sent to aggregation node, and then by converging
Vibration data is sent to storage equipment 2 and data analysis center 3 by node.
In an advantageous embodiment, the sensor node according to current remaining adjust itself communication away from
From, comprising:
(1) the adjustable communication distance range of sensor node is set as [Hmin,Hmax], HminIt is adjustable for sensor node
Minimal communications distance, HmaxFor the adjustable maximum communication distance of sensor node, sensor node adjusts oneself at the beginning
Communication distance be Hmax；
(2) sensor node periodically updates the communication distance of itself, more new formula according to current remaining are as follows:
In formula, HiIt (e) is sensor node i in e-th of period updated communication distance, HiIt (e-1) is sensor node

The maximum communication distance of section, s1、s2For preset weight coefficient.
In the present embodiment, sensor node in each neighbor node, select communication the maximum neighbor node of weight as
Next-hop, wherein the calculation formula of communication weight is innovatively provided, by the calculation formula it is found that each relay node distance
There is the neighbor node closer, communication distance is bigger bigger probability to be elected as next-hop.
The present embodiment is based on communication Weight selected next-hop, can optimize the communication lines of sensor node as much as possible by road
Diameter, shortens the distance of vibration data transmission, to reduce the energy consumption of vibration data transmission aspect, further decreases the vibration of system
Data acquisition cost.
In one embodiment, each relay node have locomotive function, aggregation node periodically collect each relay node and
The energy information of each sensor node, and the sensor node of relay node and directly communicate with it is calculated according to energy information
Energy density；Wherein, the energy density of relay node a calculates according to the following formula:
In formula, LaFor the energy density of relay node a, WabFor b-th of sensor node with relay node a direct communication
Current remaining, naFor the sensor node number with relay node a direct communication, HaFor the communication of the relay node a
Distance；
The energy density of sensor node calculates according to the following formula:
In formula, LabFor the energy density of b-th of sensor node with relay node a direct communication, WbcFor the b
The current remaining of c-th of neighbor node of a sensor node, nbFor the neighbor node of b-th of sensor node
Number, HbFor the communication distance of b-th of sensor node；
When the energy density of any relay node a is less than the mean energy density of the sensor node of directly communicate with it
When, aggregation node calculates the average residual energy with all the sensors node of relay node a direct communication, with relay node
In the sensor node of a direct communication, current remaining is greater than the sensor node of the average residual energy as benchmark
Node calculates the position of centre of gravity of all datum nodes, and sends move to relay node a, and the move includes
The information of the position of centre of gravity, the relay node a are moved to the position of centre of gravity after receiving the move；
Wherein, using aggregation node as origin, if the position coordinates with c-th of datum node of relay node a direct communication
For (xak,yak,zak), then with the calculation formula of the position of centre of gravity of all datum nodes of relay node a direct communication are as follows:
In formula, OaFor the position of centre of gravity of all datum nodes with relay node a direct communication, qaIt is straight with relay node a
Connect the number of the datum node of letter.
Sensor node near relay node not only transmits the vibration data of oneself acquisition, also wants other biographies of relay forwarding
The vibration data of sensor node, therefore the sensor node near relay node compares the sensor node far from relay node
More vibration datas are sent, therefore are easy to produce Energy volution near relay node.
Based on this problem, the present embodiment is less than the sensor of directly communicate with it when the energy density of any relay node a
When the mean energy density of node, relay node a will be mobile to the position of centre of gravity of all datum nodes of directly communicate with it.
The present embodiment can be avoided so that relay node advantageously allows as far as possible to the higher sensor node movement of energy
The neighbouring lower sensor node of energy is since the variation of distance no longer undertakes relay task, so that it is lower to reduce the neighbouring energy
Sensor node energy consumption, effectively avoid above-mentioned Energy volution phenomenon.
Finally it should be noted that use above scene is merely illustrative of the technical solution of the present invention, rather than to the present invention
The limitation of protection scope, although being explained in detail referring to preferred application scene to the present invention, the ordinary skill people of this field
Member is it should be appreciated that can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from technical solution of the present invention
Spirit and scope.
