A kind of ad hoc network method based on low-power consumption bluetooth provided by the invention, including：
Hub judges whether the leaf node of respond request networking or new hub, if the determination result is YES, then exists
Ask to establish bluetooth connection between the leaf node or new hub and the hub of response of networking, turn into the hub of response
Next stage equipment；
Wherein, in the state of all hubs all fill in upper level equipment, sentenced by the hub in next stage equipment
It is disconnected whether respond request networking leaf node or new hub, if the determination result is YES, then in the leaf section of request networking
Bluetooth connection is established between point or new hub and the hub of response, turns into the next stage equipment of the hub of response.
In the present invention, the priority of leaf node can be set to be less than the priority of new hub.For example, ask simultaneously
The leaf node of networking and new hub, the networking of the hub meeting new hub of preferential answering are asked and establish connection.Meanwhile
In the state of all hubs in upper level equipment fill and include leaf node in connected next stage equipment, upper one
Hub in level equipment preferentially disconnects the leaf node in connected next stage equipment, and with asking the new line concentration of networking
Device establishes bluetooth connection, until all hubs in upper level equipment fill new hub as next stage equipment.
Each equipment (hub and leaf node) in network has a unique device number.Hub passes through basis
White list judges whether the leaf node of respond request networking or new hub.
Based on the above-mentioned ad hoc network method based on low-power consumption bluetooth, the present invention also provide it is a kind of based on low-power consumption bluetooth from
Group network system, including：At least one hub, judge whether the leaf node of respond request networking or new hub, if sentencing
Disconnected result is yes, then establishes bluetooth connection between the leaf node or new hub and the hub of response of request networking,
As the next stage equipment of the hub of response；
Wherein, in the state of all hubs all fill in upper level equipment, sentenced by the hub in next stage equipment
It is disconnected whether respond request networking leaf node or new hub, if the determination result is YES, then in the leaf section of request networking
Bluetooth connection is established between point or new hub and the hub of response, turns into the next stage equipment of the hub of response.
The priority of leaf node is less than the priority of new hub.For example, the leaf node of networking and new is asked simultaneously
Hub, the networking of the hub meeting new hub of preferential answering are asked and establish connection.It is meanwhile all in upper level equipment
In the state of hub fills and includes leaf node in connected next stage equipment, the hub in upper level equipment is excellent
The leaf node in connected next stage equipment is first disconnected, and with asking the new hub of networking to establish bluetooth connection, directly
All hubs in supreme first device fill new hub as next stage equipment.
Each equipment (hub and leaf node) in network has a unique device number.Hub passes through basis
White list judges whether the leaf node of respond request networking or new hub.
As shown in figure 1, have two roles in the network of the present invention, one be no extended capability leaf node 2, in addition
One hub 1 for being responsible for network route and extension.
Hub is the core for routeing and extending as network, and the hub of network connection also has the function of gateway concurrently.
Each hub can connect 8~16 equipment, and (this is primarily limited to bluetooth protocol repertory in itself, if following bluetooth protocol repertory liter
Level can then connect more equipment), these equipment can be the node of no extended capability or with extended capability
Hub.The difference of hub and leaf node maximum is that hub is the main controller for being connected to the equipment of its subordinate
(master), while it is a slave unit (slave) of higher level's hub of itself connection again, i.e., hub has master slave mode
Simultaneous characteristic.And leaf node, because without extended capability, therefore one of its higher level's hub is intended only as from setting
It is standby, only slave pattern.Hub priority when connection is established is higher than common leaf node.
Pass through the routing function of hub between leaf node in network, it is possible to achieve " transparent " is point-to-point two-way
Communication.Certainly, the both-way communication of multi-to-multi can also be based on the real-time performance.
The networking at least needs a hub (being referred to as Root Hub) in networking, and Root Hub connects completely no
When be constantly in the state of monitoring.When a new leaf node or hub are opened, this new equipment (new leaf
Node or hub) broadcast singal can be sent, Root Hub is determined whether after receiving this signal by contrasting " white list "
Allow new equipment to add network, if it is allowed, then establishing the link with this new equipment, and keep, new equipment is in the company of foundation
Also gone off the air after connecing.The process by that analogy, untill Root Hub has filled equipment.Assuming that there is a new leaf node
It is opened, the leaf node can also send broadcast singal request and add network, but now Root Hub will not reply.In order to allow
The new leaf node adds network, it is necessary to be extended to network, it is necessary to increases a new hub, the new hub can quilt
It is arranged in the subordinate of Root Hub.New hub can also broadcast when being opened, and Root Hub finds there is a new hub requirement
Add networking, it is also assumed that the new hub is allowed to add network, is kicked in the equipment that Root Hub can connect from oneself subordinate
Go out an equipment, usually first kick out of common leaf node (because the priority of node is less than hub), thus can be empty
Go out a link to hub.Then, new hub and Root Hub establish link, and keep.Now kicked just now by root node
The equipment for going out network continues the broadcast state for keeping request to network, and Root Hub is full again due to being connected to new hub
State, will not comprehend the networking request.But have vacant link below new hub, therefore new hub can respond into
Net is asked and establishes connection.So, whole network does not just need the automatic of human intervention to extend.By that analogy, the network can
Constantly to extend.
Each equipment in network has a unique device number, and this number can be defined by user oneself, as long as
Do not repeated in present networks.When a leaf node is wanted and another leaf node communicates, packet is sent out
Toward the hub of oneself higher level.Each hub maintains the list of devices being connected to below oneself, and the hub is sentenced first
Disconnected this to be accessed equipment be oneself or oneself below equipment.Meanwhile if in equipment below the hub again
When having other hubs, the packet can also be delivered to subordinate's hub, and subordinate's hub also can be according to the packet
The device number to be accessed goes to inquire about following equipment, and the hub can wait Query Result.If Query Result is negative, that
Packet is sent to oneself higher level's hub by the hub, and higher level's hub can do similar action.Until packet is sent
Toward destination, and return to corresponding response.
