According to embodiments of the present invention, it is provided that a kind of method of figure layout, Fig. 1 is the flow chart of the method, specifically includes Step 101-104:

Step 101: default control node, and determine other nodes according to syntopy list and control between node Big jumping figure, has the syntopy between node in syntopy list.

In the embodiment of the present invention, controlling node is the node in bosom, according to this control node toward other nodes of external expansion. Node relationships list has the syntopy between multiple node and each node, i.e. can be true according to syntopy list Whether have syntopy between fixed two nodes, i.e. whether one of them node is the neighbor node of another node.Specifically , to join with the node relationships list of a kind of form and be shown in Table 1, form 1 shows the adjacent pass of 16 nodes (0-15) System, wherein 1 representative has syntopy, and 0 represents without syntopy, symbolRepresent the syntopy putting aside two nodes.

Table 1

Step 102: determine multiple node cycle successively for the center of circle controlling node, the quantity of node cycle and maximum hop count mutually Cause, and the corresponding jumping figure of each node cycle.

In the embodiment of the present invention, after arranging control node, it is laid in other nodes to control the node joint as the center of circle On some ring；Meanwhile, the quantity of node cycle is consistent with maximum hop count, and the corresponding jumping figure of each node cycle, jumping figure is the biggest, node The radius of ring is the biggest." jumping figure " in the embodiment of the present invention refers to " and the jumping figure controlled between node ", and maximum hop count is The maximum in jumping figure between all of node and control node.Node cycle all with control node as the center of circle, the most multiple nodes Ring is concentric circular, and the node cycle of outmost turns is corresponding with maximum hop count.

Step 103: successively node is laid in the relevant position of the node cycle corresponding with the jumping figure of node.

Concrete, as it has been described above, the corresponding jumping figure of each node cycle, and the jumping figure between each node and control node Determine that, therefore may determine that and node is arranged on corresponding node cycle.As shown in table 1, it is assumed that controlling node is node 0, The jumping figure between the neighbor node that node 1,2,3,4,5 is node 0, i.e. node 1,2,3,4,5 and control node is understood according to table 1 It is 1, then can node 1,2,3,4,5 be may be contained within same node cycle, referring specifically to shown in Fig. 2.

Step 104: be sequentially connected with two nodes with syntopy according to syntopy list.

After all nodes are laid in corresponding node cycle, i.e. may determine that according to syntopy list have adjacent Two nodes with syntopy are attached, i.e. may determine that the initial of all nodes by two nodes of relation afterwards Topological diagram.After determining initial topology figure, i.e. can optimize this initial topology figure according to power guiding algorithm.

A kind of figure layout method that the embodiment of the present invention provides, predetermined concentrically ringed multiple node cycles, and each joint The corresponding jumping figure of some ring, and then all of node is laid in successively on the node cycle corresponding with the jumping figure of node.We Method initializes from node coordinate starts with, and is tentatively arranged on corresponding node cycle by all nodes, so that node layout is to the greatest extent Energy model may be met, can tentatively reduce the energy of system；When optimizing this initial topology figure according to power guiding algorithm afterwards The optimization efficiency of power guiding algorithm can be improved.

In a kind of possible implementation, node " is laid in corresponding with the jumping figure of node by step 103 successively The relevant position of node cycle " specifically include step A1-A6:

Step A1: determine primary nodal point in primary nodal point ring corresponding, to control the node sector region as the center of circle, One node cycle is corresponding with jumping figure i, and i is the integer not less than zero and i+1 is not more than maximum hop count.

In the embodiment of the present invention, primary nodal point ring is a node cycle in node cycle, and it is corresponding with jumping figure i, i.e. The node that jumping figure is i that the node laid on one node cycle is and controls between node.In the embodiment of the present invention, i is the least Integer and i+1 in zero are not more than maximum hop count, i.e. 0≤i≤Max-1, and wherein, Max is maximum hop count.

Meanwhile, primary nodal point is a node on primary nodal point ring, i.e. jumping figure between primary nodal point and control node For i.The corresponding unique sector region of each node, this sector region is for determining the cloth of the down hop neighbor node of each node If position；The center of circle of this sector region is for controlling node, and primary nodal point ring only exists this primary nodal point in this sector region. Concrete, can be using the ray between node adjacent with primary nodal point on primary nodal point ring and this primary nodal point as this fan The limit in shape region.As shown in Figure 3, primary nodal point ring is the relatively roundlet in Fig. 3 to ginseng, if primary nodal point is the node 1 in Fig. 3, then Node adjacent with primary nodal point (i.e. node 1) on primary nodal point ring is node 3 and node 4, then by node 3 and primary nodal point A ray between (i.e. node 1) is as the limit (as shown by the dotted line in fig. 3) of sector region, by node 4 and primary nodal point Another ray between (i.e. node 1) is as the limit of sector region；P1 in Fig. 3 is the fan section corresponding with node 1 Territory.

Meanwhile, as i=0, primary nodal point is for controlling node, the radian of now corresponding with primary nodal point sector region It is 2 π, i.e. 360 °.As in figure 2 it is shown, node 0 is for controlling node；The corresponding sector region of this control node is whole circle, The node circular arc determined in step A3 later is whole circle.

Step A2: determine the neighbor node of primary nodal point according to syntopy list, and choose jumping figure in neighbor node Effective neighbor node for i+1.

In the embodiment of the present invention, owing to the jumping figure of primary nodal point is i, therefore the jumping figure of the neighbor node of primary nodal point is to the maximum I+1, the jumping figure of this neighbor node is likely to as i or i-1 etc., owing to the neighbor node that jumping figure is i or less has been laid in phase On the node cycle answered, therefore this type of neighbor node is not considered by step A2, thus need select next layer node cycle (i.e. The node cycle corresponding with jumping figure i+1, secondary nodal point ring the most hereinafter) node laid, i.e. jumping figure is effective neighbours of i+1 Node.

As a example by Fig. 3 and table 1, when primary nodal point is node 1, now i=1.According to above-mentioned table 1, node 1 Neighbor node include node 0,3,4,6,7,9, owing to node 0 is for controlling node, node 3,4 has been arranged at primary nodal point ring the most On, therefore do not consider；Therefore effective neighbor node of node 1 is node 6,7,9.

Step A3: determine node circular arc corresponding with sector region in secondary nodal point ring, secondary nodal point ring and jumping figure i+1 Corresponding.

In the embodiment of the present invention, sector region is to control node as the center of circle, therefore this sector region and primary nodal point ring and the Two node cycles all have crossing circular arc, only primary nodal point in the circular arc that sector region intersects with primary nodal point ring, and fan section The node circular arc that the circular arc that territory is intersected with secondary nodal point ring is in step A3, for arranging effective neighbours joint of primary nodal point Point.

Concrete, shown in Figure 3, secondary nodal point ring is bigger annulus.Primary nodal point is equipped with five nodes, respectively For node 1,2,3,4,5, the sector region of each node correspondence oneself, i.e. P1, P2, P3, P4, P5 in Fig. 3, accordingly sector Corresponding node circular arc is i.e. may determine that after region segmentation secondary nodal point ring.As a example by node 1, by effective neighbor node 6,7,9 It is arranged on corresponding node circular arc；Wherein, in Fig. 3, the node 7 on this section of node circular arc and node 9 are to need afterwards to eliminate Node, therefore Fig. 3 with the addition of No. X.

Step A4: first maximum effective neighbor node of coefficient will be closed be arranged at the centre position of node circular arc, and according to Other effective neighbor node is uniformly distributed on node circular arc by the coefficient that closes of syntopy list and effective neighbor node, has The quantity that pass coefficient is the neighbor node that effective neighbor node has of effect neighbor node.

In the embodiment of the present invention, it is first determined the pass coefficient of each node, the size according to closing coefficient can be ranked up, When closing coefficient and being identical, can be randomly ordered or be ranked up according to node ID；The pass coefficient of a certain node is the biggest, explanation There are other the most nodes and this node to have syntopy, then need preferentially to arrange the node that this pass coefficient is big.Still with table 1 He As a example by Fig. 3, owing to the neighbor node number of node 6,7,9 is respectively 4,2,4, i.e. close coefficient and be respectively 4,2,4；Therefore can be by node The 6 first effective neighbor nodes maximum as closing coefficient, and node 6 is arranged at the centre position of node circular arc, referring specifically to Shown in Fig. 3.Meanwhile, according to the coefficient that closes of syntopy list and effective neighbor node, other effective neighbor node is uniformly divided It is distributed on node circular arc, hereafter this is described in detail.

Step A5: according to other nodes in preset order repeat the above steps traversal primary nodal point ring, determine first successively The position of effective neighbor node of other nodes in node cycle.

In the embodiment of the present invention, step A1-A4 i.e. may determine that a node (i.e. first segment in primary nodal point ring Point) all effective neighbor node, owing to primary nodal point ring may be provided with multiple node, therefore need to repeat step A1-A4, traversal Other nodes in primary nodal point ring, until determining the position of all effective neighbor nodes, i.e. determine all joints on secondary nodal point ring The position of point.

Step A6: after traversal terminates, adds a process to jumping figure i, redefines primary nodal point ring, and determines first The position of effective neighbor node of all nodes in node cycle primary nodal point ring, until determining all joints in syntopy list The position of point.

Owing to there is multiple node cycle, after determining secondary nodal point ring, in addition it is also necessary to i is added a process, the most really Determining primary nodal point ring (the most above-mentioned secondary nodal point ring), circulation performs step A1-A4 again, determines on this secondary nodal point ring all Effective neighbor node of node, and therefore all of effective neighbor node is arranged at next node layer ring of this secondary nodal point ring On.Repeat the above steps, until determining the position of all nodes in syntopy list.After determining all node locations, i.e. May determine that the initial topology figure of node.

The figure layout method that the embodiment of the present invention provides, by determining effective neighbor node of primary nodal point successively, and will Effectively neighbor node is arranged on corresponding node circular arc, and the node with syntopy can be made to greatest extent at topological diagram In closest, further reduce system capacity, it is possible to reduce iterations, improve further the optimization of power guiding algorithm Efficiency.

In a kind of possible implementation, the first effective neighbor node closing coefficient maximum " is set by above-mentioned steps A4 It is placed in the centre position of node circular arc, and closes effective adjacent by other of coefficient according to syntopy list and effective neighbor node Occupy node to be uniformly distributed on node circular arc ", specifically include step B1-B4:

Step B1, the Along ent determined on node circular arc, the quantity of Along ent is identical with the quantity of effective neighbor node.

In the embodiment of the present invention, the Along ent on node circular arc is used for arranging corresponding effectively neighbor node.See Fig. 3 institute Show, for the node circular arc of node 1, be which effective neighbor node owing to node 1 has, therefore need node circular arc is carried out four Decile, to determine three Along ents；The position of Along ent is referring specifically to the position of Fig. 3 interior joint 6,7,9.

Step B2, when the quantity of effective neighbor node is odd number, the first effective neighbor node closing coefficient maximum is set It is placed in the position at the middle Along ent place of node circular arc；Or, when the quantity of effective neighbor node is even number, coefficient will be closed First maximum effective neighbor node is arranged at the position at a middle Along ent place in two middle Along ents of node circular arc Put.

In the embodiment of the present invention, when the quantity of effective neighbor node is odd number, then can be by first effective neighbor node It is arranged on middle position, the position at i.e. middle Along ent place.When the quantity of effective neighbor node is even number, at joint Point circular arc interposition is equipped with two Along ents, and one of them Along ent can be selected as set by first effective neighbor node Position.

Step B3, determine second effective neighbor node, and second effective neighbor node is arranged at and first effective neighbours The position at the Along ent place that node is adjacent；Second effective neighbor node is: except other of first effective neighbor node effective In neighbor node, the neighbor node of first effective neighbor node and/or effective neighbor node of pass coefficient maximum.

In the embodiment of the present invention, second effective node is except other effective neighbor nodes of first effective neighbor node In, the neighbor node of first effective neighbor node；Or, second effective node is to have except other of first effective neighbor node Effect neighbor node closes effective neighbor node that coefficient is maximum；Or, second effective node is except first effective neighbor node Other effective neighbor nodes in, be i.e. the neighbor node of first effective neighbor node and be again to close maximum effective adjacent of coefficient Occupy node.Concrete, after step B2 determines first effective neighbor node, it may be determined that the neighbour of this first effective neighbor node Occupy node, using this neighbor node as second effective neighbor node；When there are not first effective neighbours in effective neighbor node During the neighbor node of node, i.e. can close the maximum effective neighbor node of coefficient as second effective neighbor node.

As shown in table 1 and Fig. 3, node 6 is first effective neighbor node, and according to table 1, the neighbor node of node 6 is 1,10,11, and effectively neighbor node is node 7 and 9, therefore in effective neighbor node, there is not the neighbour of first effective neighbor node Occupy node, now according to pass coefficient magnitude, node 7 and 9 is distributed.If the neighbor node that node 7 is node 6, the most preferentially set Put node 7, node 9 is set after determining node 7 again.

Step B4, repeat the above-mentioned step determining effective neighbor node, until uniformly being divided by all of effective neighbor node It is distributed on node circular arc.

Above-mentioned steps B2-B3 for determining the position of effective neighbor node, repeated execution of steps B2-B3 in step B4, Owing to only existing a maximum first effective neighbor node closing coefficient, therefore having only to perform step B2, circulation performs step Rapid B3, and then the position of all effective neighbor nodes will be determined.

By syntopy or pass coefficient, the figure layout method that the embodiment of the present invention provides, determines that second effective neighbours save The position of point, so that the layout between effective neighbor node is more reasonable, equally reduces iterations.

In a kind of possible implementation, " the first effective neighbor node closing coefficient maximum is set in above-mentioned steps A4 It is placed in the centre position of node circular arc, and closes effective adjacent by other of coefficient according to syntopy list and effective neighbor node Occupy node to be uniformly distributed on node circular arc " before, also include step C1-C2:

Step C1, when the currently active neighbor node has been arranged on secondary nodal point ring, delete arranged currently have Effect neighbor node.

In the embodiment of the present invention, owing to needing to determine in primary nodal point ring all successively according to the traversing operation in step A5 Effective neighbor node of node, therefore performing in ergodic process, it is understood that there may be current effective neighbor node is before Ergodic process is arranged on secondary nodal point ring, thus need to delete between the currently active neighbours joint that arranged in ergodic process Point.

Seeing shown in Fig. 3 and Biao 1, primary nodal point ring is the annulus of inner ring.If the preset order in step A5 is inverse clock Sequentially, and first determine effective neighbor node of node 1, determine effective neighbor node of node 3,2,5,4 the most successively.Determining During effective neighbor node of node 3, it is node 8 and 9 according to effective neighbor node that table 1 understands node 3；Due to node 9 It is arranged on node circular arc corresponding with sector region P1 in secondary nodal point ring, therefore needs deletion corresponding with sector region P1 Node circular arc on node 9, on the node circular arc of node 3 correspondence, again determine the position of node 9.

Step C2, when the neighbor node that the currently active neighbor node is one or more secondary nodal point, determine first segment Perpendicular bisector between point with the distance farthest secondary nodal point of primary nodal point, and the friendship of perpendicular bisector and secondary nodal point ring Point, and the currently active neighbor node is arranged at point of intersection；Secondary nodal point is its on primary nodal point ring in addition to primary nodal point The node that he has traveled through.

In the embodiment of the present invention, secondary nodal point is other joints traveled through on primary nodal point ring in addition to primary nodal point Point.If the neighbor node that the currently active neighbor node is the secondary nodal point having stepped through, then determining the effective adjacent of secondary nodal point This currently active neighbor node is arranged on secondary nodal point ring when occupying node.Therefore determining effective neighbours of primary nodal point During node, owing to the currently active neighbor node is of effective neighbor node, i.e. it is also the neighbor node of primary nodal point, This currently active neighbor node i.e. is the neighbor node of primary nodal point and secondary nodal point simultaneously；In other words, determine in step C1 There is the currently active neighbor node the most configured out-of-date, then may determine that in step C2, certainly exist secondary nodal point.This Time determine the perpendicular bisector between primary nodal point and the distance farthest secondary nodal point of primary nodal point, and perpendicular bisector and the The intersection point of two node cycles；The currently active neighbor node is arranged at point of intersection.Owing to this perpendicular bisector has with secondary nodal point ring Two intersection points, therefore the currently active neighbor node specifically can be arranged at the point of intersection that distance primary nodal point is nearer.

Concrete, still as a example by the example shown in step C1, deleting the node circle corresponding with sector region P1 After node 9 on arc, owing to node 9 is the neighbor node of node 1, also it is the neighbor node of node 3；Now distance first segment The farthest secondary nodal point of point is node 1, therefore determines node 1 and the perpendicular bisector defining between 3, and determines and second section The intersection point of some ring, is arranged at this point of intersection, referring specifically to shown in Fig. 3 by node 9.

Preferably, this currently active neighbor node includes above-mentioned first effectively neighbor node or second effective neighbours joint Point.In the embodiment of the present invention, before determining the position of effective neighbor node, it is required to perform step C1-C2.I.e. above-mentioned Before step B2 and B3, need to perform step C1-C2.

The method flow of figure layout is discussed in detail below by an embodiment.

In embodiments of the present invention, syntopy list ginseng is shown in Table 1, and controlling node is node 0, then arrange topological diagram Process specific as follows:

First, first node cycle, i.e. i=0 are set.Referring now to shown in Fig. 2, the fan section corresponding with controlling node The radian in territory is 2 π, i.e. node circular arc is whole circle, and first node cycle arranges the node that jumping figure is 1, i.e. controls node Neighbor node.Determine the Along ent on node circular arc afterwards；Determine five Along ents on circle.The most just close coefficient maximum Node 1 be placed on an Along ent of this circle, determine the neighbor node of node 1 according to table 1, the jumping figure of its interior joint 3,4 is 1；Node 3 forward in syntopy list is selected to be placed on the left side of node 1.

Next is put and closes the node 2 that coefficient is less: understanding this node 2 has 3,5 two jumping figures to be the neighbor node of, due to joint Point 3 has been distributed on circle, then node 2 is placed on its side；Then node 4 is put, it is known that node 4 has 1,5 two jumping figures to be the neighbour of Occupy node, then determine the position of node 4 and 5 according to these 2 with the syntopy layouted.Now control a jumping joint of node Point has been distributed on first lap circle the most.

Now, owing to only one of which controls node, therefore need not perform traversing operation, directly using first circle as the One node cycle carries out next step operation.

Shown in Figure 3, first with the center of circle as summit, bundle of rays the is drawn at the center of two adjacent nodes on primary nodal point ring of crossing Two node cycle deciles, are used for being distributed the neighbor node of primary nodal point on primary nodal point ring.

First using node 1 maximum for pass coefficient as primary nodal point, the adjacency table of node 1 is checked, it is known that this node 1 Having 3,4,6,7,9 totally five neighbor nodes, wherein 3,4 nodes have been distributed on primary nodal point ring and have not the most considered further that this 2 point, therefore Effectively neighbor node is node 6,7,9；Node 6 be jumping figure be to close, in two, the neighbor node that coefficient is maximum, be placed on and with the center of circle be The position of the ray of node 1 and the intersection point of secondary nodal point ring is crossed on summit, and other jumping figures are that the neighbor node of two is then according to adjacent pass It is that the order of table is evenly distributed in around this node, is distributed in the range of the node circle corresponding for sector region P1 in Fig. 3 Arc.

With the maximum coefficient node 1 that closes in primary nodal point ring as starting point, counterclockwise traversal jumping figure be one node 3,2,5, 4, check the adjacency table of node.If detecting, its neighbor node has been distributed on this circle circle, then remove the position of this node.

Concrete, seeing Fig. 3, it is known that start to lay its effective neighbor node from node 3, its jumping figure is effective neighbours of two Node has 8,9, it is known that its maximum coefficient neighbor node 8 node 1 with the first lap having stepped through that closes without syntopy, then will Node 8 is placed on the position of the intersection point crossing the ray of node 3 and the second circle circle with the center of circle for summit；Node 9 and first traveled through Node 1 in node cycle has syntopy, removes the node 9 position at this circle circle, does summit with node 1 and 3 two somes the end of for The isosceles triangle being positioned on this circle, the position on summit is the position of this node 9, and so far the neighbor node of node 3 completes Layout.

Next lays the neighbor node of node 2, and its effective neighbor node of two jumpings has 7,10,11, and wherein maximum relation is several sections of Point 7 is also the neighbor node of node 1, then removing node 7 is in the position of secondary nodal point ring, pushes up with node 1 and 2 two somes the end of for Point is positioned at the isosceles triangle on secondary nodal point ring, and the position on summit is the position of this node 7；Simultaneously, it is known that the position of node 7 Put and overlap with node 8, be then placed on the side of node 8；10 and 11 nodes are then evenly distributed in this according to the order of adjacency table Around node, distribution is in the range of the sector region P3 in Fig. 3.

Then laying effective neighbor node of node 5, its two hop neighbors node has 10,11, wherein maximum pass coefficient node 10 have syntopy with node 2, then removing node 10 is in the position of secondary nodal point ring, does summit with node 1 and 2 two somes the end of for Being positioned at the isosceles triangle on secondary nodal point ring, the position on summit had both been the position of this node 10；Simultaneously node 11 still with node 2 There is syntopy, layout the most after the same method, it is known that node 11 is identical with the position of 10, then node 11 is placed on node 10 Side, and in ensureing this node 11 sector region P4 in figure 3.

Finally laying the neighbor node of node 4, its effective neighbor node of two jumpings has 11,12, wherein maximum pass coefficient node 11 all have syntopy with node 2 and 5, then removing node 11 is in the position of secondary nodal point ring, with apart from two farthest nodes 2 Doing, the end of for, the isosceles triangle that summit is positioned on secondary nodal point ring with 4, the position on summit had both been the position of this point, and node 12 is then put In sector region P5 in figure 3.The most complete layouting of whole two hop nodes.

Repeat the above steps afterwards, in the embodiment of the present invention, for convenience of description, makees the node cycle corresponding with jumping figure 3 It it is the 3rd node cycle.Shown in Figure 4, first with the center of circle as summit, bundle of rays is drawn at the center crossing inner lane upper two adjacent nodes of circle 3rd node cycle decile, is distributed the neighbor node of secondary nodal point link point.

Check the adjacency table of secondary nodal point node on the ring, start to travel through counterclockwise with the maximum coefficient node 6 that closes of this circle Node on secondary nodal point ring, it is known that the neighbours of node 6 have 1,13,14, its interior joint 1 is the point in primary nodal point link, therefore Ignoring this node, node 13 and 14 is evenly distributed on the circular arc corresponding to this node, sees the sector region P6 of Fig. 4.Secondly Checking the neighbor list of node 9, its neighbor node has 1,3,13,15, and node 1 and 3 is the node on primary nodal point ring, therefore neglects Slightly this node, node 13 and inner lane node 6 have syntopy, then do summit with node 6 and 9 end of for and be positioned on the 3rd node cycle Isosceles triangle, the position on summit is the position of this point, and node 15 is then placed on the respective nodes circular arc seeing Fig. 4.It After check the neighbor node of other nodes on secondary nodal point ring again, if neighbor node is inner lane node (i.e. primary nodal point ring or Some on two node cycles) then ignore this node, if the neighbor node node the most traversed with this circle has syntopy, with distance Two farthest nodes are the isosceles triangle doing that summit is positioned on this circle in the end, and the position on summit had both been the position of this point, if nothing Node is then evenly distributed on the circular arc corresponding to this node by syntopy.Until secondary nodal point link point has traveled through the most, Now the neighbor node of secondary nodal point node on the ring completes to layout the most.

Continue to check the adjacency table of the node in outmost turns circle (being now the 3rd node cycle), until the number of turns is with the longest Jumping figure is identical, and the most all node locations all have determined that.Now it is sequentially connected with two nodes with syntopy, completes and open up Flutter the initialization of figure, shown in Figure 5.
