Aggregation networks is a kind of common application scenarios in wireless network, and data ordinary node from network is transferred to one
Individual or multiple aggregation nodes (Sink).After aggregation node obtains the data of network, data can be launched further
Process, or store data in data base.Network shown in Fig. 1 has an aggregation node, and other is all general
The information of logical node is sent to this aggregation node.But, when the distribution of wireless network becomes big, will in network
Comprise substantial amounts of node.If using single aggregation node, distant node needs a routed path the longest
Just can transmit data to convergence center.This can cause the delay of data to become big, and packet loss increases.In order to solve these
Problem, can increase multiple aggregation node, as shown in Figure 2 in a network.When there is multiple aggregation node, network
Ordinary node can send the data to all of aggregation node.But under more scenes, node has only to number
The aggregation node minimum according to being sent to a Metric.Usually, the different aggregation nodes net by other form
Network is attached.
Ordinary node sends data to the routed path of aggregation node and is referred to as converging route.Usually, routing algorithm utilizes
Network topological information, is calculated routed path according to Metric minimum principle.When the link circuit condition of network changes,
The cost of existing routed path is it may happen that change, and now routing algorithm needs to adjust in time, selects one more preferably
Path.When routing algorithm adjusts routed path, need to avoid the generation of route loop.Route loop can cause data
There is substantial amounts of invalid forwarding in bag, and network causes the biggest negative effect.If the ordinary node generation chain in network
Road fault or node failure, the routed path through this node will change.Therefore, the node broken down from
Aggregation node is the nearest, and the impact on route is the biggest.If aggregation node itself breaks down, great deal of nodes can carry out road
By adjustment, cause network confusion, be greatly increased generation route loop and the probability of invalid route.Current system is many
The mode using increment sequence number (Sequence) judges that aggregation node is the most effective.But, the method faces sequence number model
Enclose and overflow and the problem of numerical value winding.Meanwhile, if aggregation node is restarted or network have employed dormancy mechanism, easily
Cause the sequence number in network chaotic.

Difference is then thought and is met update condition.Wherein, this ordinary node can be by the information of state bag and its aggregation node state
In table, the information of corresponding aggregation node compares, if their information is identical, then illustrates that this ordinary node has connect
Received this state bag, it is not necessary to be further processed；On the contrary, if their information is different, then it is assumed that meet more
New Terms, needs to be updated the aggregation node state table of oneself.
In one embodiment, if this ordinary node is in rebooting status, thinks and meet update condition.Wherein,
Rebooting status is a kind of special state of node, and it can represent that node powers on from off-mode and restart, or receive into
Enter the instruction of rebooting status, or node terminates dormancy and enters duty.Once this ordinary node is in rebooting status,
Then think and meet update condition, need the aggregation node state table of oneself is updated.
In one embodiment, if restarting in state bag is designated as true and serial number 0, thinks and meet renewal
Condition.Wherein, in this embodiment, this ordinary node can judge with restarting instruction according to the sequence number in state bag
State bag is the need of process.It is designated as very if restarted, serial number 0 simultaneously, illustrate that aggregation node restarts,
Need to reset the content of corresponding convergent node information table.
In one embodiment, if the sequence number in state bag is more than correspondence aggregation node in aggregation node state table
Sequence number is then thought and is met update condition.Wherein, if the sequence number in state bag is more than correspondence in aggregation node state table
Sequence number, illustrates the content that the information of state bag comprises renewal, needs to replace the content of state table.Wherein, sequence number is one
Individual integer, there will be integer range during realizing and overflows and the problem of numerical value winding (Wrap-around), because of
This, in the present embodiment, need consideration to process these unusual conditions when relatively sequence number size.Assume serial number length
Positive integer for 1Byte, then its scope is 0～255.If current sequence number S=255, it add 1 after take
Value is S '=0.Now, occur in that the problem that serial number range overflows, its value generation winding.Usually, for understanding
Certainly this problem, it is judged that take following principle during the size of S and S ': if S < S ' and S '-S < L/2, then it is assumed that
S is less than S '；If S > S ' and S-S ' > L/2, still believe that S is less than S '.Wherein, L is the model of sequence number value

Step 901: this ordinary node judges that the information of state bag is corresponding with the aggregation node state table of oneself and converges joint
The information of point is the most identical, if it is different, then think and meet update condition, if identical, then performs step 902；
Step 902: this ordinary node judges whether present node is in rebooting status, if it is, think and meet more
New Terms, otherwise performs step 903；
Step 903: it is true and whether sequence number is 0 that this ordinary node judges that restarting in state bag indicates whether, as
Fruit is, then it is assumed that meet update condition, otherwise performs step 904；
Step 904: this ordinary node judges that the sequence number in state bag is the most corresponding more than in aggregation node state table and converges
The sequence number of node, if it is, think and meet update condition, otherwise it is assumed that be unsatisfactory for update condition.
In step 804, in the case of meeting update condition, replace, by the information of state bag, the convergence that this locality preserves
The information of corresponding aggregation node in node state table.
By above method, receive after the state bag of aggregation node at ordinary node, according to this state bag
Information and the information of aggregation node state table that preserves of their own, update the aggregation node state table of oneself, slap at any time
Hold the nearest state of aggregation node, it is to avoid because can not find that the fault of aggregation node carries out invalid routing operations and causes
Network confusion.
In step 603, this ordinary node can also check the routing table of oneself, if the aggregation node in state bag
Address is positioned in its routing table, then explanation needs to forward this state bag, then this ordinary node forwards receive to be somebody's turn to do
State bag.On the contrary, if the aggregation node address in state bag is the most in its routing table, this state bag is not carried out
Forward operation.Thus, ordinary node may also operate as the effect of relaying while grasping the state of aggregation node.
In an embodiment of the present embodiment, this ordinary node can also be examined according to the aggregation node state table of oneself
