Condition is recorded and is analyzed, the timely early warning when soil environment data are unsatisfactory for condition, is realized and is improved the automatic of farmland monitoring
Change degree and accuracy of data acquisition.
In a kind of mode that can be realized, sensor node model uses Boolean sense model, sensor node perception
Radius isomery, the perception radius of any sensor node is in [Lmin,Lmax] in range, wherein LmaxAnd LminIt is divided into sensor node
The bound of the perception radius；When disposing sensor node, the monitoring region of deployment sensor node is determined, which is drawn
It is divided into ρ section, and the quantity allotted of the sensor node of each section is calculated, comprising:
(1) sensor node quantity of deployment is set as K, to meet network coverage requirement, determines K according to the following formula,
Successively label is carried out to each section according to the sequence that monitoring dynamics demand grows from weak to strong, thus the section that the dynamics demand of monitoring is most weak
Marked as 1, and monitor the strongest section of dynamics demand marked as ρ:
In formula, E is the volume size for monitoring region；
(2) each section for monitoring region is assigned different power levels according to the size of label, wherein the section marked as b
Power level are as follows:
Rb=eb-ρ
In formula, RbIndicate the power level of the section marked as b, e is natural constant；
(3) sensor node quantity that the section should be distributed is calculated according to the power level of section:
In formula, KbIndicate the sensor node quantity that the section marked as b should be distributed, RaFor the power of the section marked as a
Grade.
The monitoring region of setting is divided into multiple sections by the present embodiment, and specifically proposes the sensor node of each section
Quantity distribution mechanism, in the distribution mechanism, the sensor node quantity for requiring setting that should dispose according to the network coverage first,
Then it is that corresponding power level is arranged in each section according to monitoring dynamics demand, finally distributes sensor node according to power level.This implementation
Example enable to sensor node Relatively centralized in monitoring the higher region of dynamics demand, other area sensor Node distributions compared with
It is few, so as to further increase the network coverage in relatively important monitoring region, relative to random placement sensor node
Mode, optimize network topology structure, and then promote the Monitoring Performance of wireless sensor network.
In one embodiment, the corresponding deployment sensor section of the sensor node quantity that should be distributed according to each section
Point determines the sensor node maximum possible covering of section d when any section d disposes sensor node according to the following formula
Rate Gd:
In formula, LhFor the perception radius of h-th of sensor node in the d of section, EdFor the volume size of section d, KdFor section
The sensor node quantity distributed in d；
Distance/(i, j) of the arbitrary neighborhood disposed in the d of section two sensor nodes i, j should meet:
Work as GdWhen≤1,
Work as GdWhen > 1,
In formula, L5For the perception radius of sensor node i, LjFor the perception radius of sensor node j, LminFor sensor section
The lower limit of point the perception radius.
The present embodiment calculates the sensor node maximum possible coverage rate of each section according to the actual conditions of each section, and
The distance range of adjacent sensors node has been determined according to sensor node maximum possible coverage rate.It is determined according to the present embodiment
Distance range disposes sensor node, enable to the overlapping of sensing range between two neighboring sensor node be in compared with
It is reasonable level, is conducive to avoid can not achieve higher coverage rate between sensor node due to hypertelorism.
In one embodiment, when netinit, sensor node passes through the information exchange with other sensors node
Determine neighbor node, wherein neighbor node is remaining sensor node in sensor node communication range；Aggregation node
Xiang Yuqi distance is less than setting apart from lower limit SminSensor node send suspend mode instruction message, receive suspend mode instruction disappear
The sensor node of breath carries out compared with apart from nearest neighbor node, if sensor node is relative to apart from nearest neighbour
Node is occupied closer to aggregation node, then sends dormancy instruction to apart from nearest neighbor node, is saved with enabling apart from nearest neighbours
Point enters dormant state, otherwise enables and oneself enters dormant state.In one embodiment, aggregation node will be less than with its distance and set
It is fixed apart from lower limit SminSensor node and the nearest neighbor node of respective distances as neighboring node, aggregation node is regular
The energy message of the neighboring node of non-suspend mode is collected, and whether energy is met according to the neighboring node that energy message detects non-suspend mode
Condition sends replacement notice to the neighboring node for meeting energy condition；The neighboring node for receiving replacement notice wakes up its distance
Then nearest neighbor node oneself enters dormant state.
Wherein, the energy condition is set are as follows:
In formula, Ql is the current remaining of neighboring node l, QhFor the current of h-th in network non-suspend mode neighboring node
Dump energy, n are the quantity of non-suspend mode neighboring node in network, QminFor the minimum energy value of the maintenance node state of setting.
Sensor node near aggregation node not only transmit oneself acquisition soil environment data, also want relay forwarding its
The soil environment data of his sensor node, therefore the sensor node near aggregation node compares the biography far from aggregation node
Sensor node will send more soil environment data, so wireless sensor network is easy to produce energy near aggregation node
Cavity.Based on this problem, the present embodiment defines neighboring node and energy condition, and neighboring node is unsatisfactory in energy
When the energy condition of setting, it is waken up apart from nearest neighbor node, then oneself enters dormant state.
The energy that the present embodiment is capable of neighboring node rapidly depletes, to effectively avoid above-mentioned Energy volution phenomenon, extends
The life span of wireless sensor network.
The above embodiment of the present invention acquires soil environment data by wireless sensor network, can be in real time by the feelings of soil
Condition is recorded and is analyzed, the timely early warning when soil environment data are unsatisfactory for condition, is realized and is improved the automatic of farmland monitoring
Change degree and accuracy of data acquisition.
