Fig. 1 is the network topology schematic diagram of the wireless sense network of the embodiment of the present invention.As shown in Figure 1, the wireless sensing
Net is a wireless sensor network with multi-hop relay comprising Centroid 1, relay node 2 and terminal node 3.It is practical
In, all nodes can have environmental parameter detection function (that is, being sensing node), and different classes of node has
There is different communication functions in network.As can be seen from FIG. 1, in the embodiment of the present invention, wireless sense network is tree network, center
Node 1 does not have father node, and as the root node of the tree network, all sensing datas of acquisition the whole network simultaneously further upload to
Data center.There are one the child node of the father node and at least one communication connection that communicate to connect, his fathers for each tool of relay node 2
Node can be that Centroid 1 can also be relay node 2, and child node can be that relay node 2 can also be terminal node
3.Leaf node of the terminal node 3 as tree network, only father node, father node node 1 or relaying can save centered on
Point 2.
It should be understood that in embodiments of the present invention, tree network refers to having between any two node and only one logical
The network on road.
In embodiments of the present invention, Centroid 1 is for broadcasting this node beacon (Beacon).Beacon is for carrying out activity
Period allocated is synchronous with node.Wherein, when entire wireless sense network is initialized, when Centroid 1 is added in a beacon
Between stab, the timestamp indicate data frame in corresponding time slot occupied by Centroid 1, the time slot by centered on node 1 work
The dynamic period.Relay node 2 is for relaying signal and acquisition sensing data, by all sensing datas of sub-network connected to it
Upper level is uploaded to after collection, until being transferred to Centroid 1.Terminal node 3 is only used for acquisition sensing data and uploads.
Before determining cycle of activity, the node in need that network is added receive all beacons, and according to pre- set pattern
It then selects in communication range, the node in wireless sensor network is used as father node, for example, selecting hop count according to beacon
Minimum node is as father node.As a result, at the beginning of network is established, the radio node that can be communicated with Centroid can be by center
Node is selected as father node to which wireless sense network be added, and what the other radio nodes of distance farther out can be gradually receives relay node hair
The beacon that send and select radio node appropriate as father node and wireless sense network be added, finally adaptively complete wireless pass
Feel the networking of net.After being added in network, relay node 2 can receive Beacon analysis and obtain all receptions in initialization
To beacon in timestamp, choose unappropriated time slot as the cycle of activity of this node and obtain this node in network
The cycle of activity of father node；And the letter that transmission circuit broadcasts this node is opened in the cycle of activity of this node after the completion of initialization

Relay node 2 outside the cycle of activity of this node and father node in a dormant state.Centroid 1 is in this node
Cycle of activity is outside in a dormant state.Terminal node 3 enters dormant state after sensing data is sent.
Fig. 2 is that the wireless sensor network of the embodiment of the present invention carries out the flow chart of netinit.Fig. 3 is the flow of Fig. 2
The topological schematic diagram for the wireless sensor network that figure is related to.In order to make it easy to understand, Fig. 2 and 3 is only to include Centroid, two relayings
It is illustrated for the simple network topology of node and three terminal nodes.Wherein, Centroid 1 respectively with relay node 2a
And 2b connections, relay node 2a are connected thereto as the father node of terminal node 3a and 3b.Relay node 2b is as terminal section
The father node of point 3c is connected thereto.
As shown in Fig. 2, when carrying out netinit, all time slots of data frame are unoccupied, and Centroid 1 is first
The timestamp of this node is added in a beacon, occupies one scheduled (such as first time slot) or time slot S1 selected at random makees
For the cycle of activity of itself, and broadcast the beacon.In general, the node in wireless sense network is arranged to receive the node near it
Beacon, between each other distance be more than a certain range of node mutually can not directly receive beacon.In the example in figure 2, terminal
Node 3a-3c can not receive the beacon B1 of Centroid broadcast, and only relay node 2a and 2b can receive beacon B1.
Beacon B1 is first received in relay node 2a to select unappropriated time slot S2 as this node according to the timestamp in beacon
Cycle of activity, the timestamp for characterizing this node cycle of activity is added in a beacon, leads to together together with the timestamp of Centroid 1
Beacon B2 is crossed to be broadcasted.
At this moment there are two kinds of situations, if relay node 2b can receive relay node 2a simultaneously and Centroid 1 is wide
The beacon B1 and beacon B2 broadcast, then it can know occupied there are two time slot according to beacon B1 and beacon B2, can select
Unappropriated third time slot S2 is selected to be broadcasted as the cycle of activity of itself, and by beacon B3.
If relay node 2b farther out, jumps the range communicated, then it is only capable of in receiving apart from relay node 2a beyond one
The beacon B1 that heart node 1 is broadcasted, at this point, Centroid 1 be due to that can receive beacon B2, it can be in advance in the beacon of broadcast
The occupied time slots of relay node 2a are indicated in B1.It can select a time slot as the work of itself according to beacon B1 as a result,
The dynamic period, and the time slot of its occupancy and known is broadcasted by beacon B3.Thus, it is possible to ensure the active cycle of all relay nodes
Phase and the cycle of activity of its neighbor node and the neighbor node of neighbor node are all different, so as to avoid conflicting and do
It disturbs.
Meanwhile relay node 2a and 2b regard Centroid 1 as its father node, while basis according to advance network configuration
Beacon B1 knows the cycle of activity of father node.
Terminal node 3a and 3b according to advance network configuration using relay node 2a as father node, after receiving beacon
It searches the cycle of activity for obtaining relay node 2a, and establishes and connect with relay node 2a.
Terminal node 3c, using relay node 2b as father node, acquisition is searched after receiving beacon according to advance configuration
The cycle of activity of relay node 2b, and establish a connection.
Initialization procedure is completed as a result,.
Fig. 4 is that the wireless sensor network of the embodiment of the present invention carries out the flow chart of sensing data acquisition.Fig. 5 is of the invention real
Apply the distribution schematic diagram of the communication time slot of example.As shown in Fig. 4, when carrying out data acquisition, terminal node 3a-3c is known
The cycle of activity of corresponding father node.Wherein, the cycle of activity of relay node 2a be time slot S2, enter time slot S2 after from
It wakes up in dormant state, after being waken up, is sent first with the work for characterizing this node and neighbor node with broadcast mode
The beacon B2 of the timestamp in dynamic period, then starts to interact with child node.Its child node terminal node 3a and 3b are in time slot
It is also waken up from dormant state in S2, carries out beacon reception first after being waken up.Due to the neighbours of relay node 2a at this time
The cycle of activity of the neighbor node of node and neighbor node is not time slot S2, and therefore, terminal node 3a and 3b are only capable of receiving
To the beacon of relay node 2a, is synchronized into row clock according to the beacon, then connected by radio communication on father node 2a
Pass the sensing data that acquisition obtains.The sensing data can be the temperature detected, humidity, brightness, air pressure, specific gas
Content, parameter of equipment etc..When uploading, terminal node 3a and 3b can be sent according to scheduled sequence of addresses
It can be sent based on competition mechanism.In order to preferably save energy consumption, terminal node 3a and 3b are respectively in self-sensor number
According to dormant state can be entered after being sent, without waiting for terminate the entire cycle of activity of its father node.
In embodiments of the present invention, suspend mode refers to network node with communication close receiver, transmitter and part difference
Electrical low energy consumption state is wanted, in the dormant state, network node only runs necessary hardware (such as processor), or with spy
Surely state run control unit, while keep other pens should not hardware close, consumption electric energy it is very low.Wake-up refers to network
Node is transformed into the action of normal operating conditions from dormant state.
Similarly, relay node 2b time slot S3 during the activity of itself are waken up, when being waken up incipient first
Between the beacon of the timestamp with the cycle of activity for characterizing this node and neighbor node is sent in section with broadcast mode, then open
Beginning interacts with child node.Child node 3c receives beacon and synchronizes first, is then connected by radio communication again to relaying
Node 2b uploads the sensing data of its acquisition.
Meanwhile relay node 2a and 2b determine the cycle of activity of itself and have known corresponding father node (Centroid
1) time slot S1 cycle of activity.In time slot S1, Centroid 1 is waken up, and is sent beacon with the forms of broadcasting first, is wrapped in beacon
Include the timestamp of the timestamp of the time slot S1 of its occupancy and the time slot S2 and S3 of its neighbor node 2a and 2b occupancy.Relay node
The child node of node 1 is also waken up in time slot S1 centered on 2a and 2b.After relay node 2a and 2b are waken up, receive first
Beacon synchronizes.The letter for passing through reception Centroid due to the relay node 2a and 2b wireless sensing net nodes jumped as first
It number synchronizes, therefore, can ensure synchronous with Centroid.Further, relay node 2a and 2b can be at subsequent
The beacon synchronous with Centroid clock is sent in the cycle of activity of node makes its child node keep synchronizing with its Centroid.
And so on, the scale of the wireless sense network regardless of the embodiment of the present invention can ensure all relay nodes and end
End node is synchronous with Centroid holding.After sending beacon, relay node 2a and 2b will be in the work of upper this node
The sensing data for the child node that the dynamic period receives and the sensing data of this node acquisition are packaged as a big superframe or data
Packet connects by radio communication to be uploaded to Centroid 1.It is similar with relay node 2a communications with terminal node 3a, 3b, relaying section
Point 2a and 2b can also be sent according to scheduled sequence of addresses send based on competition mechanism.
It can be seen that mode piecemeal of the wireless sense network of the embodiment of the present invention based on the time-division is led to
Letter.Since time that when network size is slightly larger, each node is waken up is much smaller than the time of suspend mode, therefore relative to existing skill
Art can reply reduction energy consumption so that Centroid and relay node can be based on battery powered and run.
Relay node chooses activity of the unappropriated time cycle as this node according to the timestamp in beacon as a result,
It period and the cycle of activity for obtaining father node is only waken up in the cycle of activity of this node and father node and carries out data transmission and lead to
Letter, meanwhile, Centroid, which is also only waken up in the cycle of activity of oneself, to be carried out data transmission and communicates, and the two is equal at other times
In a dormant state, thus, it is possible to which the energy consumption of relay node and Centroid is greatly reduced so that all of wireless sense network set
It is standby to be battery powered driving, it is suitable for the application of in the high environment of wild environment and horsepower requirements.
In addition, the wireless sense network of the embodiment of the present invention can also carry out data distributing from Centroid.The downlink issued
Data can be configuration-direct etc..
Specifically, as shown in fig. 6, relay node or terminal node as child node wake up in the cycle of activity of father node
Inquiry message inquiry father node is sent afterwards and whether there is downlink data, and relay node or terminal node as father node exist
Downlink data is carried out when being sent to the data of corresponding child node to issue.It specifically, can be in the data packet of downlink data
The information of all relay nodes between routing iinformation namely the destination node and Centroid of downlink data is configured, as a result, root
According to routing iinformation, may be implemented downlink data being issued to specific destination node by a big period.
Due to being transmitted by challenge-response mode during the activity of father node, it is not necessary to dramatically increase each wireless biography
Downlink data still can be issued to specific destination node by the activity time of sense net node, realize configuration for network and
Control.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for those skilled in the art
