Brief description of the drawings
Fig. 1 is the schematic diagram of wireless sensor network node self-organizing network system.
Embodiment
Technical scheme is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of wireless sensor network node self-organizing network system, including Surveillance center, telegon, sensor
Node, base-station node, very first time judge module, the second time judgment module, first number judge module, second number judge
Module and timer；The Surveillance center, telegon, sensor node, base-station node are sequentially connected, the base-station node with it is upper
Position machine is connected, the timer and the connection of the second time judgment module；
The Surveillance center is used to monitor the process for setting up network, receives data；
The telegon is responsible for setting up network, and the node for adding network is communicated, receive data, issue control with
And convey data to monitoring center；
Adding the node of network includes simplifying node, leader cluster node.
The function to be realized of telegon is：The initial chemical industry that each chip on sensor node bottom plate is coordinated in field is first had to
Make, then telegon will can complete MANET.Multiple telegons are there are in sensor network, after telegon is opened, it
Can MANET, wait simplify the addition of node at any time.Simplifying the major function of node is：First have to complete the first of modules
Beginningization, then will complete application and add network, after adding successfully, repeat gathered data and be sent to the work of telegon.
The present invention uses the cluster networking plan based on cluster head priority, when leader cluster node is successfully joined telegon network
In, respective short address space is obtained respectively to be used for setting up extension undernet.Before mobile node networking, according to cluster head section
Point reaches the reliable routing path length of coordinator node, carries out priority addressing to leader cluster node respectively.Path is shorter, preferentially
Level is higher.When mobile node exceeds the communication range of place cluster head, it exits present cluster, selects it to receive range of signal
Interior, then the cluster head of highest priority updates its relevant information.Clustering schemes based on priority are relative to nearest clustering schemes
Turnover collection group frequency is smaller, and a cluster of mobile node can be kept as far as possible, and mobile node cluster energy consumption is reduced.The party
Case can significantly decrease communication delay.
The sensor node is used to send the request other request instruction of distribution stage to base-station node；
The base-station node receives the other request of distribution stage that sensor node is sent, and sends distribution to sensor node
Level instruction.
Very first time judge module, the distribution rank for judging whether to receive base-station node in the first preset time refers to
Order；
First number judge module, for judging not receiving in the first preset time during distribution level instruction, judges institute
State sensor node and send whether the request other number of times of distribution stage reaches the first preset times；
Whether the second time judgment module, the time for judging to send broadcasting command reaches the second preset time；
Second number judge module, for when reaching the second preset time, judging that the sensor node sends broadcast
Whether the number of times of order reaches the second preset times；
The timer is used for the time that setting sensor node keeps low power consumpting state.
The network that the telegon is set up uses Mesh topological structures.
The telegon, which is set up, uses the cluster networking based on cluster head priority in network development process.
The wireless sensor node hardware includes processor module, radio-frequency communication module, power module, sensor die
Block, external memory modules.
The Msp430F1611 single-chip microcomputers that the processing controller module is used.It is a kind of 16 mixing of super low-power consumption
Signal controller, can be at lower voltages with super low-power consumption operation, under 1.8~3.6V voltages, 1MHz Clock
Operation, and with 5 kinds of battery saving modes and very short wakeup time.
The chip of the radio-frequency communication module selects CC2420.Meet the 2.4GHz direct sequences of IEEE802.15.4 specifications
Spread spectrum mode RF transceiver, based on SmartRF03 technologies, is made with 0.18 μm of CMOS technology, and data rate reaches 250kbps.
CC2420 is communicated using SPI serial programmables interface protocol and microcontroller.SPI interface by CCCSn, CCSI, CCSO and
Totally 4 pins are constituted CCSCLK.Processor accesses CC2420 internal registers and memory block by SPI interface.System is used
Totally 4 pin represent the state of transceiving data by CCSFD, CCFIFO, CCFIFOP and CCCCA.
The present invention is put into low-power consumption mode during concrete application after base-station node power-up initializing.Sensor section
After point power-up initializing, sensor node can be sent to base-station node first asks distribution stage other order very first time to judge mould
Block, the distribution level instruction for judging whether to receive base-station node in the first preset time；Sensor node first can be to
Base-station node sends the request other order of distribution stage.First number judge module judges not receiving distribution in the first preset time
During level instruction, judge that the sensor node sends whether the request other number of times of distribution stage reaches the first preset times；Second
Time judgment module judges whether the time for sending broadcasting command reaches the second preset time；Sensor node is saved to base station again
Point sends the request other order of distribution stage；When reaching the second preset time, second time number judge module judges the sensor
Whether the number of times that node sends broadcasting command reaches the second preset times；If receiving base-station node distribution in the second preset time
The rank sensor node packet of Self-organizing Information will be sent to base-station node.If do not had in the second preset time
There is the rank node for receiving base-station node distribution to be waken up from low power consumpting state and send the request other order of distribution stage again, such as
This is circulated, after sensor node, which is sent, asks distribution stage other order in base station to reach the setting upper limit, but still without determination certainly
During oneself rank in a network, the node will send broadcasting command to the whole network, subsequently into low power consumpting state and open timing
Device.Timing comes back to transmitting broadcasting command state to node.When the number of times that sensor node launches broadcast reaches setting
During value, the node will be arranged the response message received, determine oneself rank in a network, and determine higher level,
The relevant information of at the same level and downstream site.Superior node sends the packet for including these information to the node again, until data
Bag is sent to base-station node, so that it is determined that the topological structure of whole network.
The foregoing is only a preferred embodiment of the present invention, protection scope of the present invention not limited to this, any ripe
Those skilled in the art are known in the technical scope of present disclosure, the letter for the technical scheme that can be become apparent to
Altered or equivalence replacement are each fallen within protection scope of the present invention.
