In the data informationization acquisition, management and analysis system and method for above-described embodiment, under sensor node selection
It is specific to execute when one hop node:
(1) the data forwarding Superiority Value of itself is calculated when each sensor node is initial:
In formula, QiIndicate that the data forwarding Superiority Value of sensor node i, d (i, sink) are that sensor node i is saved to convergence
The distance of point, d (i, k) are distance of the sensor node i to its k-th of neighbor node, and d (k, sink) is k-th of neighbour
Distance of the node to aggregation node, niFor the neighbor node number that sensor node i has, λ is the weight coefficient of setting, and 0
< λ < 0.5, the neighbor node are the sensor node in sensor node i communication range；
(2) sensor node and each neighbor node carry out information exchange, construct neighboring node list, obtain each neighbor node
Data forwarding advantage value information, and store into neighboring node list corresponding position；When selecting next-hop node, sensing
Device node calculates the weight of each neighbor node according to the following formula, and selects the maximum neighbor node of weight as next-hop section
Point:
In formula, WABIndicate the weight of the neighbor node B of sensor node A, QABFor the data forwarding of the neighbor node B
Superiority Value, d (A, B) are distance of the sensor node A to the neighbor node B, RAFor the communication distance of sensor node A, PBFor

Value, VBFor using the neighbor node B as the sensor node quantity of next-hop node, nBFor the neighbours of the neighbor node B
Number of nodes, ω are the regulation coefficient of setting；e1、e2For the weight coefficient and e of setting1+e2=1.
The present embodiment innovatively sets the calculation formula of the data forwarding Superiority Value of sensor node, the calculation formula
Positional relationship between sensor node and ambient sensors node, aggregation node carries out based on data forwarding Superiority Value
It calculates, can preferably measure position advantage situation when sensor node forwarding data, be determined for subsequent sensor node next
Hop node provides basic data reference, to be conducive to improve the efficiency that sensor node determines next-hop node；The present embodiment
Energy, position based on neighbor node and three factors of next-hop node are elected to be by other sensors node, innovatively
The calculation formula of weight is set, which enables to energy, position more to have more greatly for the neighbor node of advantage
Probability carry out data forwarding, and the calculation formula is provided with attenuation coefficientEnable to sensor node
When selecting next-hop node, avoid selecting the same neighbor node as next-hop section with other multiple sensor nodes as far as possible
Point improves the reliability of data routing to be conducive to the load of balanced periphery neighbor node.
In one embodiment, next-hop node judges the processing condition data of itself every a cycle Δ T, if meeting
Following condition, the next-hop node send early warning information to its all upper hop sensor node, promote to receive the early warning information
Sensor node reselect next-hop node:
In formula, PlFor the current remaining of next-hop node l, Pl0For the primary power of next-hop node l, τlIt is next
Up to the present hop node l judges the number of the processing condition data of itself, when next-hop node l x-th judges whether to meet
When the condition, τl=x；HlFor the size of the currently available caching of next-hop node l, HminFor the minimum cache threshold of setting, f
(Pl-Pmin) it is to judge value function, work as Pl-PminWhen > 0, f (Pl-Pmin)=1, works as Pl-PminWhen≤0, f (Pl-Pmin)=0, δ
Delay the factor for the preset unit data congestion based on distance, the value range of δ is [0.01,0.03], d0For preset number
Unit distance, d are forwarded according to packetL, minFor next-hop node l and its distance apart from nearest upper hop sensor node, dL, max
For next-hop node l and its distance apart from farthest upper hop sensor node,
The present embodiment devises the feedback early warning mechanism of next-hop node, wherein it is every innovatively to set next-hop node
The Rule of judgment of the processing condition data of itself is judged every a cycle Δ T.The slow of next-hop node is determined in the Rule of judgment
When depositing situation, the currently available cache size of next-hop node is not only allowed for, and considers next-hop node because with each
The case where there is distance and data congestion caused to delay in upper hop sensor node, so as to the caching feelings of next-hop node
The determination of condition has more robustness and accuracy.When determining the energy situation of next-hop node in the Rule of judgment, not only allow for
The current remaining of next-hop node, and consider next-hop node within a period can consumable energy so that right
The determination of the energy situation of next-hop node has more robustness and accuracy.In the present embodiment, which should in satisfaction
Early warning information is sent to a jump set sensor node thereon when Rule of judgment, promotes to receive the sensor node of the early warning information again
Select next-hop node, advantageously reduce next-hop node because data congestion spends that big or energy is insufficient and packet loss it is general
Rate, and then improve the reliability and efficiency of data communication.
In one embodiment, when initial, sensor node constructs neighbours' section according to the information exchange with each neighbor node
Point list, and the alternative ability value of each neighbor node is accordingly calculated, by the storage of alternative ability value into neighboring node list
Corresponding position；It is big in current remaining before next-hop node sends early warning information to its all upper hop sensor node
In 1.5PminNeighbor node in select the maximum neighbor node of alternative ability value as recommended node, the early warning information packet
Include the mark of the recommended node；
After sensor node receives the early warning information, if the recommended node is the neighbor node of oneself, sensor
Node directly selects the recommended node as new next-hop node；Otherwise, sensor node calculates the weight of each neighbor node,
And select the maximum neighbor node of weight as next-hop node；
The calculation formula of the alternative ability value are as follows:
In formula, UljFor the alternative ability value of the neighbor node j of next-hop node l, ClIt is saved for the neighbours of next-hop node l
Point quantity, CjFor the neighbor node quantity of the neighbor node j, Cl∩CjFor the next-hop node l and the neighbor node j
Shared neighbor node quantity, d (l, j) are the next-hop node l at a distance from the neighbor node j, dL, maxUnder described
The maximum distance of one hop node l and its neighbor node, z1For the preset impact factor based on Social Relation degree, z1Value model
It encloses for [0.3,0.4], z2For preset distance influence factor, z2Value range be [0.4,0.5].
The present embodiment creatively sets the recommendation mechanisms of next-hop node, and sensor node is (under including in the mechanism
One hop node) the alternative ability value that precalculates each neighbor node, by the storage of alternative ability value into neighboring node list
Corresponding position.When next-hop node no longer undertakes the task of data forwarding, selected in the qualified neighbor node of energy
The maximum neighbor node of alternative ability value is selected as recommended node, sends recommended node to its all upper hop sensor node
Identification information, with to upper hop sensor node provide one selection.The present embodiment can be improved upper hop sensor node
The efficiency for reselecting next-hop node advantageously reduces sensor node and reselects the energy consumption of next-hop node, to save
Save the cost of energy of data acquisition.
