When the slave node free time in new ad hoc network, new informational table of nodes is sent to idle slave section by source node
Point.
It is further improved as the present invention, nodal information includes number information and physical address information.
It is further improved as the present invention, new informational table of nodes includes temporal information, and source node is periodically according to certainly
The nodal information update informational table of nodes and temporal information of all nodes in networking.
Be further improved as the present invention, the step of all nodes new informational table of nodes being sent in ad hoc network it
Afterwards, further include:
Source node periodically acquires each from the temporal information of the destination node information table of node;
Source node judge destination node information table temporal information whether the new temporal information with new informational table of nodes
It is identical;
When the temporal information of destination node information table is with new temporal information difference, source node will be with destination node information
The corresponding nodal information from node of table is rejected from new informational table of nodes.
Be further improved as the present invention, the step of all nodes new informational table of nodes being sent in ad hoc network it
Afterwards, further include:
When disconnect initiate communication request from node to target from node when, target from nodal test itself whether it is new from
In networking;
When target from node not in new ad hoc network when, target judges disconnect from node whether being stored with node from node
Whether information table and the informational table of nodes are identical as itself informational table of nodes of storage;
When disconnect from node be stored with informational table of nodes and it is identical as the informational table of nodes of target from node when, then target from
Node is established from node with disconnection and is communicated to connect.
Be further improved as the present invention, target from nodal test itself whether after the step in new ad hoc network,
Further include:
When target from node in new ad hoc network when, target from node judge disconnect from node whether be stored with node letter
It ceases table and whether the informational table of nodes is identical as itself informational table of nodes of storage;
When disconnect from node be stored with informational table of nodes and it is identical as the informational table of nodes of target from node when, then target from
Node is established from node with disconnection and is communicated to connect.
It is further improved as the present invention, whether target judges to disconnect from node is stored with informational table of nodes from node and is somebody's turn to do
Whether informational table of nodes further include with after the identical step of informational table of nodes of itself storage:
When disconnection is not stored with informational table of nodes from node or is differed from the informational table of nodes of node with target, target
It is instructed from node feeding back re-authentication to disconnecting from node;
Source node be verified again disconnection from the key identification information of node when, disconnection built from node from node with target
Vertical communication connection, and will be switched off being updated new informational table of nodes from the nodal information of node.
To solve the above-mentioned problems, the present invention also provides a kind of self-organizing network systems of ultraviolet optical-fiber network comprising saves in source
For point at least one from node, source node includes transmitting terminal, control terminal, receiving terminal and memory from node with each, is deposited
