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, described wireless sense network is a radio sensing network with multi-hop relay, and it comprises Centroid 1, via node 2 and terminal node 3.In reality, all nodes all can have environmental parameter measuring ability (also namely, being sensing node), and different classes of node has and has different communication functions in a network.According to Fig. 1, in the embodiment of the present invention, wireless sense network is tree network, and Centroid 1 does not have father node, as the root node of described tree network, gathers all sensing datas of the whole network and uploads to data center further.Each via node 2 has the father node of a communication connection and the child node of at least one communication connection, and its father node can be Centroid 1 also can be via node 2, and its child node can be via node 2 also can be terminal node 3.Terminal node 3, as the leaf node of tree network, only has father node, its father node can centered by node 1 or via node 2.
Should be understood that in embodiments of the present invention, tree network refers to be had between any two nodes and only to have the network of a path.
In embodiments of the present invention, Centroid 1 is for broadcasting this node beacon (Beacon).Beacon is used for carrying out distribution cycle of activity and synchronisation of nodes.Wherein, when whole wireless sense network carries out initialization, Centroid 1 is joining day stamp in a beacon, and this timestamp represents that time slot corresponding in Frame is taken by Centroid 1, and this time slot is by the cycle of activity as Centroid 1.Via node 2 is for repeating signal and gather sensing data, uploads to upper level, until be transferred to Centroid 1 after being collected by all sensing datas of connected sub-network.Terminal node 3 is only for gathering sensing data and uploading.
Before determining cycle of activity, all nodes adding network that needs all receive all beacons, and select in communication range according to pre-defined rule, and the node be in radio sensing network is used as father node, such as, select the minimum node of jumping figure as father node according to beacon.Thus, at the beginning of network is set up, the radio node that can communicate with Centroid can be elected Centroid as father node thus add wireless sense network, other distant radio node progressively can receive the beacon of via node transmission and select suitable radio node to add wireless sense network as father node, finally completes the networking of wireless sense network adaptively.Joining after in network, via node 2 can when initialization, receive Beacon analysis and obtain timestamp in all beacons received, choose unappropriated time slot as the cycle of activity of this node and obtain the cycle of activity of the father node of this node in network; And after initialization completes, open transmission circuit in the cycle of activity of this node broadcast the beacon of this node and receive the sensing data that child node uploads, open transmission circuit in the cycle of activity of father node and upload the sensing data self gathered and the sensing data received from child node.
Terminal node 3 obtains cycle of activity as the via node of father node for receiving beacon when initialization, and within the cycle of activity of father node, opens transmission circuit send sensing data.
Via node 2 is in resting state outside the cycle of activity of this node and father node.Centroid 1 is in resting state outside the cycle of activity of this node.Terminal node 3 enters resting state after sensing data transmission terminates.
Fig. 2 is the flow chart that the radio sensing network of the embodiment of the present invention carries out netinit.Fig. 3 is the topological schematic diagram of the radio sensing network that the flow chart of Fig. 2 relates to.For the ease of understanding, Fig. 2 and 3 is described for the simple network topology only comprising Centroid, two via nodes and three terminal nodes.Wherein, Centroid 1 is connected with via node 2a and 2b respectively, and via node 2a is connected with it as the father node of terminal node 3a and 3b.Via node 2b is connected with it as the father node of terminal node 3c.
As shown in Figure 2, when carrying out netinit, all time slots of Frame are all unoccupied, Centroid 1 adds the timestamp of this node first in a beacon, take predetermined (such as first time slot) or the random selected time slot S1 cycle of activity as self, and broadcast this beacon.Usually, the node in wireless sense network is set to the beacon of the node received near it, and the node that distance exceedes certain limit each other directly cannot receive beacon mutually.In the example in figure 2, terminal node 3a-3c cannot receive the beacon B1 of Centroid broadcast, only has via node 2a and 2b can receive beacon B1.First receiving beacon B1 in via node 2a can according to the timestamp in beacon, select unappropriated time slot S2 as the cycle of activity of this node, add the timestamp characterizing this node cycle of activity in a beacon, the timestamp together with Centroid 1 is together broadcasted by beacon B2.
At this moment there are two kinds of situations, if via node 2b can receive beacon B1 and the beacon B2 of via node 2a and Centroid 1 broadcast simultaneously, then according to beacon B1 and beacon B2, it can know that to have two time slots occupied, it can select unappropriated 3rd time slot S2 as the cycle of activity of self, and is broadcasted by beacon B3.
If 2a is far away for via node 2b distance via node, exceed the scope of a jumping communication, then it only can receive the beacon B1 that Centroid 1 is broadcasted, now, Centroid 1, owing to can receive beacon B2, therefore can indicate the time slot shared by via node 2a in advance in the beacon B1 of broadcast.Thus, it can select a time slot as the cycle of activity of self according to beacon B1, and broadcasts its time slot taken and known by beacon B3.Thus, can ensure that the cycle of activity of the neighbor node of the cycle of activity of all via nodes and its neighbor node and neighbor node is all not identical, thus can avoid conflict and disturb.
Meanwhile, via node 2a and 2b according to network configuration in advance using Centroid 1 as its father node, know the cycle of activity of father node according to beacon B1 simultaneously.
Terminal node 3a and 3b according to network configuration in advance using via node 2a as father node, it searches the cycle of activity obtaining via node 2a after receiving beacon, and connects with via node 2a.
Terminal node 3c according to configuration in advance using via node 2b as father node, it searches the cycle of activity obtaining via node 2b after receiving beacon, and connects with it.
Thus, initialization procedure completes.
Fig. 4 is the flow chart that the radio sensing network of the embodiment of the present invention carries out sensing data collection.Fig. 5 is the distribution schematic diagram of the communication time slot of the embodiment of the present invention.As shown in Figure 3, when carrying out data acquisition, terminal node 3a-3c all knows the cycle of activity of corresponding father node.Wherein, the cycle of activity of via node 2a is time slot S2, and it wakes up, after being waken up after entering this time slot S2 from resting state, first it send the beacon B2 of the timestamp with the cycle of activity characterizing this node and neighbor node with broadcast mode, then start to carry out alternately with child node.Its child node terminal node 3a and 3b also wakes up in time slot S2 from resting state, and first it carry out beacon reception after being waken up.Because the cycle of activity of the now neighbor node of via node 2a and the neighbor node of neighbor node is not all time slot S2, therefore, terminal node 3a and 3b only can receive the beacon of via node 2a, it carries out clock synchronous according to this beacon, is then connected by radio communication and uploads to father node 2a the sensing data gathering and obtain.Described sensing data can for the temperature, humidity, brightness, air pressure, the content of specific gas, the parameter of equipment etc. detected.When uploading, terminal node 3a and 3b can carry out sending according to predetermined sequence of addresses and also can send based on competition mechanism.In order to better save energy consumption, terminal node 3a and 3b can enter resting state respectively after self-sensor data are sent, and need not wait for that the whole cycle of activity of its father node terminates.
In embodiments of the present invention, dormancy refers to that network node wants electric low energy consumption state respectively with communication close receiver, transmitter and part, in the dormant state, network node only runs necessary hardware (such as processor), or with specifically state operation control assembly, keep other pen not want hardware to close, its electric energy consumed is very low simultaneously.Wake up and refer to that network node is transformed into the action of normal operating conditions from resting state.
Similarly, via node 2b time slot S3 between the active stage of self is waken up, first it be waken up the beacon sending the timestamp with the cycle of activity characterizing this node and neighbor node in the incipient time period with broadcast mode, then starts to carry out alternately with child node.First child node 3c receives beacon carries out synchronously, and then is connected the sensing data uploading its collection to via node 2b by radio communication.
Meanwhile, via node 2a and 2b determines the cycle of activity of self and has known time slot S1 cycle of activity of corresponding father node (Centroid 1).At time slot S1, Centroid 1 is waken up, and first it send beacon with the forms of broadcasting, and beacon comprises the timestamp of time slot S2 and S3 that the timestamp of the time slot S1 that it takies and its neighbor node 2a and 2b take.Via node 2a and 2b is also waken up at time slot S1 as the child node of Centroid 1.After via node 2a and 2b is waken up, first receives beacon and carry out synchronously.Because via node 2a and 2b is undertaken synchronously as the wireless sensing net node that first jumps by the signal of receiving center node, therefore, it can ensure synchronous with Centroid.Further, via node 2a and 2b can send and make its child node and its Centroid keep synchronous with the beacon of Centroid clock synchronous within the cycle of activity of this follow-up node.By that analogy, regardless of the scale of the wireless sense network of the embodiment of the present invention, all can ensure that all via nodes keep synchronous with terminal node and Centroid.After in transmission, beacon terminates, sensing data and the sensing data of this node collection of the child node that the cycle of activity at upper this node receives by via node 2a with 2b are packaged as a large superframe or packet and are connected by radio communication and upload to Centroid 1.With terminal node 3a, 3b and via node 2a communication class seemingly, via node 2a and 2b can carry out sending according to predetermined sequence of addresses and also can send based on competition mechanism.
As can be seen here, the wireless sense network of the embodiment of the present invention communicates based on the mode piecemeal of time-division.Due to when network size is slightly large, the time that each node is waken up, much smaller than the time of dormancy, therefore can reply reduction energy consumption relative to prior art, and Centroid and via node can be run based on powered battery.
Thus, via node is chosen the unappropriated time cycle according to the timestamp in beacon and is obtained the cycle of activity of father node as the cycle of activity of this node, only wake up in this node and the cycle of activity of father node and carry out transfer of data and communicate, simultaneously, Centroid is also only waken up in the cycle of activity of oneself and carries out transfer of data and communicate, both are all being in resting state At All Other Times, thus, significantly can reduce the energy consumption of via node and Centroid, the all devices of wireless sense network can battery-poweredly be driven, be suitable for being applied to wild environment and the high environment of 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 data issued can be configuration-direct etc.
Particularly, as shown in Figure 6, after waking up the cycle of activity of father node, send apply for information inquiry father node as the via node of child node or terminal node and whether there is downlink data, carry out downlink data as the via node of father node or terminal node when there are the data that will send to corresponding child node and issue.Particularly, can configure routing iinformation in the packet of downlink data, be also the information of all via nodes between the destination node of downlink data and Centroid, thus, according to routing iinformation, downlink data can be realized to be issued to specific destination node by large cycle.
Owing to being transmitted by challenge-response mode within the active stage of father node, downlink data still can be issued to specific destination node by the activity time that significantly need not increase each wireless sensing net node, realizes the configuration for network and control.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, to those skilled in the art, the present invention can have various change and change.All do within spirit of the present invention and principle any amendment, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
