It is noted that the method that the embodiment of the present invention proposes is suitable for the probe deployment of electric power wireless private network, it is particularly suitable for LTE electricity
The probe deployment of power wireless private network.
Fig. 1 is a kind of flow diagram of electric power wireless private network probe deployment method of the embodiment of the present invention, such as Fig. 1 institute
Show, a kind of electric power wireless private network probe deployment method includes:
101, non-directed graph is obtained according to the topological structure of electric power wireless private network.
Specifically, the topological structure of electric power wireless private network includes the link connection between network node and each network node,
Non-directed graph is obtained according to the topological structure of electric power wireless private network, i.e., the network node in electric power wireless private network is converted into non-directed graph
In vertex, the link connection between each network node is converted to the side in non-directed graph.In non-directed graph, the weight on any vertex is
The probe deployment cost of the vertex correspondence network node, i.e., the weight on any vertex are used to be characterized in the reality of vertex correspondence representative
The lower deployment cost that probe needs to pay is disposed on the electric power wireless private network network node of border.
102, obtain the Minimum Vertex Covering collection of non-directed graph.
Specifically, the definition of Minimum Vertex Covering is given below: given non-directed graph G=(V, E), wherein V is non-directed graph
Vertex set, E is the line set of non-directed graph, if there is vertex set M, so that each edge is all associated in G, i.e. it is all in G
E, all at least containing a vertex in vertex set M, then such set M is referred to as a vertex covering of non-directed graph G.If depositing
In the vertex covering that some set M is non-directed graph G, and there is no other set for including less vertex can cover entirely
Figure, then set M is referred to as a Minimum Vertex Covering of non-directed graph G.
After obtaining non-directed graph according to the topological structure of electric power wireless private network, the probe deployment problem of electric power wireless private network is
It can be abstracted as the minimal covering problem of non-directed graph, be described in detail below:
Wherein, v is the vertex of non-directed graph, and n is the quantity on vertex in non-directed graph, c=[c1, c2..., cn] it is each vertex
The probe deployment cost of corresponding network node, x=[x1, x2..., xn] it is vertex covering collection, it is the vector that length is n, (aij)
For the adjacency matrix of non-directed graph, size is n × n, and constraint condition is as follows:

Problem, and using the probe cyclization rate of Minimum Vertex Covering collection as the index of evaluation probe deployment scheme, to ensure in probe portion
After the completion of administration, even if there is the case where probe destruction, the whole monitoring performance of electric power wireless private network will not be influenced, is effectively improved
The stability and reliability of electric power wireless private network monitoring system.
Based on the above embodiment, a kind of electric power wireless private network probe deployment method, 102, obtain the minimum vertex of non-directed graph
Covering collection, specifically includes:
1021, obtain undirected Graph Col oring.
Specifically, minimal covering problem maximum independent set is converted to solve.Assuming that non-directed graph G=(V, E),
V is the vertex set of non-directed graph, and E is the line set of non-directed graph, and S is a subset of V,If any two top in S
Point is non-conterminous in G, then S is referred to as an independent sets of G.If for the independent sets S of any G, if do not included in G any |
S ' | > | S | independent sets S ' (| S | the element number for referring to set, that is, the gesture gathered), then S is referred to as the maximum independent set of G.
1022, it is based on maximum independent set, obtains Minimum Vertex Covering collection.Specifically, Minimum Vertex Covering collection=vertex set
Close V- maximum independent set S.
In the embodiment of the present invention, minimal covering problem is converted into maximum independent set problem and is solved, to evade

Number of edges is m, and N (v) indicates all adjacent node set of node v.Give all link nodes set Π=[v1, v2...,
vn], the independent sets S and corresponding auxiliary array B of a link nodes set Π is constructed, every unitary in array B is assisted
Plain B [vi] indicate each network node v in link nodes set ΠiAid mark.Assuming that the first preset value is 0, second is default
Value is 1.Firstly, enabling all B [vi] it is all 0, secondly carry out following judgement: if B [viThen set S is added in node vi by]=0, and
Set B [vj] it is 1, wherein vjFor all and viAdjacent node.Finally obtaining set S is independent sets.
The above are the acquisition methods of any independent sets, in order to obtain several independent sets, so that any in non-directed graph
Vertex is necessarily present in a certain or certain several independent sets in several above-mentioned independent sets, can be accomplished in that
Add first vertex v in set ΠaInto independent sets, and the acquisition methods structure based on any of the above-described independent sets
Build independent sets.By set Π ring shift left one, i.e., by vertex vaIt is moved to last position of set Π, it again will be in set Π
First vertex be added in another independent sets, construct another independent sets, repeat the step several times, obtain several independences
Collection.
Based on any of the above-described embodiment, a kind of electric power wireless private network probe deployment method, by the number of vertex for being included maximum

Specifically, when there are the independent sets that multiple number of vertex for including are maximum vertex number, for wherein any independent
Collection, sums to the weight on the vertex that the independent sets include, the weights sum on each vertex for including using the independent sets as
The weight of the independent sets.It is maximum for there are multiple included number of vertex i.e. during the selection of maximum independent set
The case where independent sets of number of vertex, needs further to be chosen according to the weight of each independent sets.
Based on any of the above-described embodiment, a kind of electric power wireless private network probe deployment method, obtain non-directed graph in can cyclization

Vertex corresponding element in adjacency matrix is set as 0；It will abut against the corresponding vertex of the element in matrix for 1 and be used as and cyclic can push up
Point, addition can cyclic vertex sets.
Herein, adjacency matrix is the matrix for characterizing neighbouring relations between vertex.Assuming that non-directed graph G=(V, E), G's
Number of vertex is n, and the adjacency matrix of G is the n rank square matrix with following property:
Scan adjacency matrix (aij), successively calculateValue, if dev (vi)=1, enables aI, 1,
aI, 2..., aI, nAnd a1, i, a2, i..., aN, iIt is 0, and repeats above procedure, until does not have dev (vi)=1 occurs.At this point, square
Node representated by the non-zero element left in battle array is can cyclic node.
