Description of the drawings
Fig. 1 is wireless network node theory of constitution structural representation of the present invention.
Fig. 2 is the schematic flow sheet of interaction of shaking hands of the invention.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
It is a kind of that the method that wireless self-organization network is set up is realized based on collision detection and competitive way, specifically include following mistake
Journey：Step 1, arrange N number of wireless network node in a network to intercept communication channel, the N is the natural number more than 1, detection
The service condition of channel；Step 2, by the method for collision detection, wireless network node X is detected in N number of wireless network node
During channel idle, the wireless network node X represents any one wireless network node, wireless network in N number of wireless network node
Nodes X sending node broadcast message, while receiving the broadcast message of N-1 wireless network node beyond wireless network node X
And record；Step 3, repeat step 1～2 are completing enumeration process, until determining the Network Central Node of network；Step 4, network
Centroid adopts time-multiplexed mode, completes the interaction of resource allocation information；Step 5, Network Central Node and itself with
N-1 outer wireless network node completes the foundation of network by way of three-way handshake interaction.The network creating method is realized
Simply, by the way of collision detection, broadcast message is sent in channel idle, can adapt to wireless self-organized network topology knot
Structure is changeable, a fairly large number of situation of wireless network node, realizes the quick foundation of wireless self-organization network.
