In a kind of mode that can be realized, if the adjustable communication distance range of sensor node is [Lmin,Lmax],
LminFor the adjustable minimal communications distance of sensor node, LmaxIt is described for the adjustable maximum communication distance of sensor node
Sensor node itself communication distance is adjusted according to current remaining, comprising:
(1) it is L that sensor node adjusts the communication distance of oneself at the beginningmax；
(2) sensor node periodically updates the communication distance of itself, more new formula according to current remaining are as follows:
In formula, LiIt (t) is sensor node i in t-th of period updated communication distance, LiIt (t-1) is sensor node
I is in the t-1 period updated communication distance, Qi(t-1) current when updating in the t-1 period for sensor node i
Dump energy, QiIt (t) is current remaining of the sensor node i when updating in t-th of period, Qi0For sensor node i's
Primary power, QminFor preset minimum energy value, ρ is preset energy factors, and 0 < ρ < 1；
(3) if the communication distance updated is less than LminWhen, the communication distance for adjusting sensor node is Lmin, and no longer update
Communication distance.
In the present embodiment, setting sensor node adjusts the communication distance of itself according to current remaining, and innovative
Ground be provided with sensor node communication distance more new formula, the formula with the current remaining of sensor node reduction
Communication distance is shortened, with the communication range of limiting sensor node, advantageously reduces the communication energy consumption of sensor node.This reality
Apply example be further arranged sensor node update communication distance be less than LminWhen, the communication distance for adjusting itself is Lmin, real
Sensor node is showed in range [Lmin,Lmax] in communication distance adjustment, avoid sensor node due to communication distance is too short
It cannot achieve the efficient communication with adjacent sensors node.
In one embodiment, sensor node selects next-hop in its neighbor node, comprising: sensor node determines
The communication weight of its each neighbor node selects the communication maximum neighbor node of weight as next-hop；Wherein communication weight is pressed
It is calculated according to following equation:
In formula, KijIndicate the communication weight of j-th of neighbor node of sensor node i, SjdFor j-th of neighbour section
Point is at a distance from d-th of relay node, SidIt is sensor node i at a distance from d-th of relay node, LjIt is adjacent for described j-th
Occupy the present communications distance of node, LminFor the adjustable minimal communications distance of sensor node, LmaxIt is adjustable for sensor node
The maximum communication distance of section, α1、α2For 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 choosing
Next-hop is selected, the communication routed path of sensor node can be optimized as much as possible, shortens the distance of soil quality parameter transmission,
To reduce the energy consumption of soil quality parameter transmission aspect, the soil quality parameter acquisition cost of system is further decreased.
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；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, the energy density of relay node a calculates according to the following formula:
In formula, VaFor the energy density of relay node a, QabFor b-th of sensor node with relay node a direct communication
Current remaining, naFor the sensor node number with relay node a direct communication, LaFor the communication of the relay node a
Distance；
The energy density of sensor node calculates according to the following formula:
In formula, VabFor the energy density of b-th of sensor node with relay node a direct communication, QbeFor the b
The current remaining of e-th of neighbor node of a sensor node, nbFor the neighbor node of b-th of sensor node
Number, LbFor the communication distance of b-th of sensor node；
Wherein, using aggregation node as origin, if the position coordinates with c-th of datum node of relay node a direct communication
For (xac,yac,zac), 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, maIt is straight with relay node a
Connect the number of the datum node of letter.
Sensor node near relay node not only transmit oneself acquisition soil quality parameter, also want relay forwarding its
The soil quality parameter of his sensor node, therefore the sensor node near relay node compares the biography far from relay node
Sensor node will send more soil quality parameters, therefore Energy volution is easy to produce near relay node.It is asked based on this
Topic, the present embodiment are close when the average energy for the sensor node that the energy density of any relay node a is less than directly communicate with it
When spending, 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 the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
