Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art are not having
There is the every other embodiment obtained under the premise of making creative work, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a kind of node cut-in methods of fusion communication, as shown in Figure 1, the node
Cut-in method may comprise steps of：
Step S101：Obtain network topology structure and non-access node.By network topology structure, can know at this stage
Communication mode between the node and node that have accessed.In addition, in network topology structure, access node can also be shown
Type.The communication site of a variety of different communication modes is supported to be known as aggregators, aggregators include three types, i.e. physical layer
Aggregators, MAC layer aggregators and multimodality fusion node.Physical layer aggregators refer to that different communication mode exists in node
The numeric field of PHY realizes fusion, shares a digital processing element, but various communication modes have the simulation process list of its own
Member.MAC layer aggregators refer to that different communication mode realizes fusion in MAC layer in node, share a MAC layer, but various
Communication mode has the PHY processing units of its own.Multimodality fusion node refers to that various communication modes have its corresponding MAC in node
And PHY.A kind of website of communication mode is only supported to be known as single communication node.Direct communication may be implemented between aggregators,
Direct communication may be implemented between aggregators and single communication node.Between the single communication node for supporting different communication mode
Direct communication is can not achieve, but can be realized and be in communication with each other by aggregators.Fig. 2 is the signal of a network topology structure
Figure, wherein the rectangle for being located at top is communication main station, and each node is directly or indirectly connected to communication main station.Make in fig. 2
Indicate that MAC layer aggregators, circle indicate physical layer aggregators with the type of different shape representation nodes, such as triangle,
Diamond shape indicates that multimodality fusion node, square indicate to support the single communication node of communication mode 1, carries the square table of oblique line
Show the single communication node for supporting communication mode 2, and dotted line indicates to be connected by communication mode 1 between node, solid line indicates section
It is connected by communication mode 2 between point.
Step S102：Any node is selected in network topology structure.It investigates one by one each in existing network topology structure
Whether a node also has the ability for accessing other nodes again.In a specific embodiment, network topology structure can be passed through
Whether the mode of node has been connected to before and after the hop count of interior joint and the node, and screening, which goes out in network topology structure, to be had again
Access the node of other node capacities.
Step S103：Judge whether the corresponding communication hop count of any node is less than preset maximum hop count.In the present embodiment
In, the purpose of default maximum hop count is to control the communication speed of the communication network after accessing new node, avoids postponing excessive.
When the hop count of already present node in network topology structure reaches preset maximum hop count, which does not have again
Access the ability of other nodes；If other nodes are connected on the already present node by mistake, it is likely to result in communication delay, it cannot
Meet the requirement of real-time Communication for Power.
Step S104：When the corresponding communication hop count of any node is less than preset maximum hop count, control any node hair
Neighbor node is sent to find message.Find message it can be found that the corresponding all neighbor nodes of any node by neighbor node.
Step S105：Judge whether any node receives corresponding feedback message.
Step S106：When any node receives corresponding feedback message, determine that corresponding non-access node is any section
The neighbor node of point.It, can be without any processing for each neighbor node found in access node；For not connecing
The each neighbor node found in ingress should try to be accessed.
Step S107：Any node is connected with any neighbor node by corresponding communication mode.In access neighbours' section
When point, it is not necessary to existing communication mode in network topology structure is sticked to, it can will be adjacent with any other feasible communication mode
Occupy node access.
Specifically, can be from communication main station, according to communication hop count, whether hop-by-hop screening node by node has access to not
Access node.For example, the first several nodes jumped that screening is directly connected with communication main station, allow above-mentioned node to attempt to distinguish successively
It is connected with non-access node by any communication mode, if being connected successfully, non-access node is accessed by the communication mode
The first hop node is stated, the second hop node in network topology structure is become.Correspondingly, in the screening for completing the first hop node with after
After continuous node access, sharp screening can be carried out to each second hop node in a like fashion and subsequent node accesses, with such
It pushes away, until communication hop count reaches preset maximum hop count or whole nodes access.
The node cut-in method of fusion communication provided in an embodiment of the present invention, in the network of existing communication network
On topological structure, break restriction of the existing communication network on communication mode, supports multi-hop communication and often jump that different lead to can be used
Letter mode can be compatible with a variety of different types of communication nodes, realize the flexible access of node, be conducive to play various communication parties
The advantages of formula, realizes the depth integration between a variety of different communication modes and mutual supplement with each other's advantages.
Due to limitation of the single communication node in communication mode selection, in practical applications, when any node and appoint
When one of one neighbor node is single communication node, using the corresponding communication mode of single communication node by single communication section
Point is connected with another node.
It, in practical applications, can be first in step s 106 due to opening of the aggregators in communication mode selection
First judge whether two communication nodes to be connected are aggregators, is aggregators for two nodes to be connected
Two nodes can be connected by situation using any communication mode, due to not limiting communication mode, enhance the spirit of node access
Activity.For example, the highest communication mode of traffic rate can be selected to connect two aggregators, to obtain higher communication speed
Degree；It is also an option that the communication mode of optimal stability, to improve the reliability of communication.
