The above embodiment of the present invention acquires soil environment monitoring data by wireless sensor network, can be in real time by soil
The case where recorded and analyzed, the timely early warning when soil environment monitoring data are unsatisfactory for condition, realize improve farmland prison
The degree of automation and monitoring accuracy of survey.
In the prior art, the sensor node near aggregation node not only transmits the soil environment monitoring number of oneself acquisition
According to also wanting the soil environment monitoring data of relay forwarding other sensors node, therefore the sensor section near aggregation node
Point will send more soil environment monitoring data compared to the sensor node far from aggregation node, so wireless sensor network
Energy volution is easy to produce near aggregation node.
Based on the above existing technology problems, in one embodiment, setting aggregation node is removable, is set in
Sensor node collection within the scope of aggregation node communication distance is combined into H, aggregation node periodically to the sensor node in set H into
Row energy monitoring, if meeting following mobile condition, the aggregation node sensor node that current remaining is more into set H is moved
It is dynamic, and according to new location updating set H:
In formula, rHFor the sensor node quantity in set H, e is the sensor node in set H, QeFor sensor node
The current remaining of e, QeuFor the current remaining of u-th of sensor node in sensor node e communication range, reFor
Sensor node quantity in sensor node e communication range, LeFor the communication radius of sensor node e, QvFor in set H
The current remaining of v-th of sensor node, LOFor the communication radius of aggregation node.
It is removable that aggregation node is arranged in the present embodiment, and innovatively defines mobile condition.The present embodiment setting convergence
Node periodically carries out energy monitoring to surrounding sensor node, and meets in the energy situation of the sensor node of surrounding and move
When dynamic condition, allow aggregation node to current remaining it is more near the mobile setting of sensor node distance, far from energy
Sensor node near less is beneficial to balance the energy of sensor node near aggregation node, reduces Energy volution phenomenon,
And then effectively extend network lifetime, improve the stability of soil environment monitoring data collection.
In one embodiment, the aggregation node sensor node that current remaining is more into set H is mobile, packet
It includes:
(1) in aggregation node set of computations H sensor node average residual energy, by current remaining in set H
Greater than the sensor node alternately destination node of the average residual energy；
(2) energy weight of alternative target node is calculated according to the following formula:
In formula, YaIndicate the energy weight of alternative target node a, QaFor the current remaining of alternative target node a, Qab
For the current remaining of b-th of sensor node in alternative target node a communication range, raIt is logical for alternative target node a
Believe the sensor node number in range, LaFor the communication radius of alternative target node a；
(3) each alternative target node is ranked up according to the descending sequence of energy weight, selects preceding 2 alternative mesh
Node is marked as destination node, if the coordinate of two destination nodes is respectively (x1,y1,z1)、(x2,y2,z2), then aggregation node
Xiang DianDirection it is mobile.
The present embodiment proposes the mobile mechanism of aggregation node, wherein the first sensor in communication range of aggregation node
Alternative target node is filtered out in node, then calculates the energy weight of each alternative target node, passes through preparatory screening, Neng Goujie
It saves and calculates time and cost.The present embodiment chooses that energy weight is maximum and secondary big alternative target node is as destination node,
And using the position of 2 destination nodes as benchmark, the moving direction of aggregation node is determined.
The present embodiment realizes the moving direction optimization of aggregation node, is conducive to make aggregation node to the biggish sensing of energy
Device node rendezvous region displacement improves the mobile efficiency of aggregation node, and then effectively extends network lifetime, improves soil
The stability that earth environmental monitoring data is collected.
Further, the moving distance upper limit is set, so that the total distance of aggregation node movement is no more than in the moving distance
Limit.
In one embodiment, the moving distance of each aggregation node calculates according to the following formula:
In formula, SwFor the moving distance of the w times aggregation node, Yw1The first aim node determined when mobile for the w times
Energy weight, Yw2The energy weight of the second target node determined when mobile for the w times, YoIt is weighed for the energy of aggregation node
Weight, Dw1,oDistance for the first aim node to aggregation node, Dw2,oFor the second target node to aggregation node
Distance, YcFor the unit energy weight of setting, ScFor the unit moving distance of setting.
The difference of energy weight of the present embodiment based on destination node and aggregation node innovatively sets aggregation node shifting
The calculation formula of dynamic distance, according to the calculation formula, if the energy weight of destination node is bigger, the moving distance of aggregation node
Also bigger.The moving distance mobile sink node that the present embodiment is calculated according to the calculation formula enables to aggregation node to true
Fixed moving direction is moved to preferably position, and the mode relative to random movement aggregation node, can save aggregation node
Mobile energy consumption, and then save soil environment monitoring data collection cost to a certain extent.
The above embodiment of the present invention acquires soil environment monitoring data by wireless sensor network, can be in real time by soil
The case where recorded and analyzed, the timely early warning when soil environment monitoring data are unsatisfactory for condition, realize improve farmland prison
The degree of automation and accuracy of data acquisition of survey.
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
Matter and range.
