Preferably, the data acquisition module 1 includes multiple agricultures being distributed in crop growth condition monitoring region
Crop monitoring node and an aggregation node, when wireless sensor network initializes, each crops monitoring node carries out sub-clustering, and
Determine that leader cluster node, crops monitoring node are sent to institute for characteristic is given birth to from the crops monitoring node in each cluster
Leader cluster node in cluster, and then received fertility characteristic is merged by leader cluster node and is sent to aggregation node.
Preferably, if the leader cluster node in crops monitoring node and place cluster is multi-hop distance, crops monitoring section
Point selects a state value optimal as next-hop crops monitoring node in neighbours' crops monitoring node, establishes itself
With the routing between neighbours' crops monitoring node, assist sending fertility characteristic by next-hop crops monitoring node
Form by give birth to characteristic be sent to leader cluster node, wherein carry out next-hop crops monitoring node selection when, specifically
It executes:
(1) set the distance between leader cluster node of crops monitoring node and place cluster as φ, by with the place cluster
The neighbours crops monitoring node of the distance between leader cluster node less than φ alternately node, crops monitoring node is to each
Alternate node broadcasts hello message, after each alternate node receives hello message, joins to crops monitoring node feedback states
Number, state parameter includes the current remaining of alternate node, the neighbours' crops monitoring node number having；
(2) crops monitoring node counts the propagation delay time of each alternate node feedback states parameter, and determination is each alternative
The state value of node chooses the maximum alternate node of state value as next-hop crops monitoring node, it is standby with this to establish itself
The routing between node is selected, if EmIndicate that the state value of m, m indicate m-th of alternate node of crops monitoring node i, EmMeter
Calculate formula are as follows:
In formula, uiFor the number of the alternate node of crops monitoring node i, Pm、QmThe respectively current remaining of m, tool
Some neighbours crops monitoring node numbers, PiFor the current remaining of crops monitoring node i, TmIndicate m feedback states ginseng
Several propagation delay times.
In the present embodiment, crops monitoring node is when selecting next-hop crops monitoring node, preferential basis and place
The distance between leader cluster node of cluster screens neighbours' crops monitoring node, can accelerate the speed of Route establishment, right
When meeting neighbours' crops monitoring node of distance condition and selecting, in the current residual for considering neighbours crops monitoring node
On the basis of energy and node degree, it is also contemplated that the timeliness of each alternate node transmission data is conducive to improve fertility characteristic
According to the efficiency of transmission.
In one embodiment, the degree of belief between leader cluster node periodical evaluation crops monitoring node, if Wλ,ν(Δ T) table
Show the degree of belief between crops monitoring node λ and next-hop crops monitoring node v in Δ T time, Wλ,ν(Δ T's) comments
Estimate formula are as follows:
In formula, Δ T is the assessment time window of setting, Uλ,v(ΔT)、Qλ,v(Δ T) is illustrated respectively in λ, v in Δ T time
Similar number between the fertility characteristic of acquisition and dissimilar number, wherein Uλ,v(Δ T)=count [Jt(λ,v)>Jξ, t=
1,2 ..., Δ T], Qλ,v(Δ T)=count [Jt(λ,v)≤Jξ, t=1,2 ..., Δ T], count [] is counting function, Jt
(λ, v) indicates the similarity between t moment λ, the fertility characteristic of v acquisition, JξFor the similarity threshold of setting, it is located at t
Moment λ acquisition fertility characteristic beIt is in the fertility characteristic of t moment v acquisitionThenqλ,v(it is downward that Δ t) is illustrated respectively in crops monitoring node λ in the Δ t time
One jumps the number that crops monitoring node v sends the successful number of fertility characteristic packet, sends fertility characteristic packet failure；
When the degree of belief between crops monitoring node and next-hop crops monitoring node is less than the degree of belief threshold of setting
When value, leader cluster node sends message to corresponding crops monitoring node, crops monitoring node receive carry out after message it is next
Jump the update of crops monitoring node.
The present embodiment is trusted according to two factor definitions of fertility characteristic relationship and communication efficiency between two nodes
The calculation formula of degree quantifies the degree of belief node, is conducive to the energy consumption for saving Trust Values Asses, under opposite raising
One jumps the update efficiency of crops monitoring node, ensures the stability of grid power transmission route intelligent monitor system；
The present embodiment carries out degree of belief using next-hop crops monitoring node of the leader cluster node to crops monitoring node
Assessment carries out the update of next-hop crops monitoring node when degree of belief threshold value of the degree of belief lower than setting, can ensure life
The forwarding of characteristic is educated, the reliability of fertility collecting characterization data is improved.
In one embodiment, when the degree of belief between crops monitoring node and next-hop crops monitoring node is less than
When the degree of belief threshold value of setting, leader cluster node also further assesses the next-hop crops monitoring node as follows:
(1) energy assessment is carried out, if the current remaining of next-hop crops monitoring node is less than its primary power
1%, determine that the next-hop crops monitoring node is error node；
(2) if the current remaining of next-hop crops monitoring node is not less than the 1% of its primary power, to next-hop
Crops monitoring node carries out assessment of breaking one's promise, if the next-hop crops monitoring node is unsatisfactory for following confidence level and determines formula,
Then determine that the next-hop crops monitoring node is node of breaking one's promise:
In formula, r is r-th of the crops monitoring node communicated with next-hop crops monitoring node v, Y indicate with it is next
Jump the crops monitoring node number of crops monitoring node v communication, Wr,v(Δ T) indicates crops monitoring node r and next-hop
Degree of belief between crops monitoring node v in Δ T time, y (Δ T) is indicated in assessment time window Δ T and next-hop
Crops monitoring node v communicates effective crops monitoring node number, wherein crops monitoring node is downward within the Δ t time
One, which jumps crops monitoring node v, sends time that the fertility successful number of characteristic packet is greater than transmission fertility characteristic packet failure
At several twice, determine that the crops monitoring node communicates effectively with next-hop crops monitoring node v, is otherwise communication nothing
Effect, C are the believability threshold of setting；
(3) the next-hop crops monitoring node progress suspend mode to error node or node of breaking one's promise is determined as.
The present embodiment carries out energy assessment and assessment of breaking one's promise using the leader cluster node crops monitoring node low to degree of belief,
Suspend mode is carried out to the next-hop crops monitoring node for being determined as error node or node of breaking one's promise, can be avoided error node or mistake
Believe that node influences the transmission of fertility characteristic, and can be avoided error node or the fertility characteristic for node acquisition of breaking one's promise
The precision for influencing whole fertility characteristic, improves the reliability of fertility collecting characterization data, extends the work of data acquisition module 1
Make the service life.
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
