Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a networking method fusing multiple communication modes, and as shown in fig. 1, the networking method can comprise the following steps:
step S101: and pre-networking by using at least two communication modes, and determining a first communication mode for first networking according to the number of access nodes and/or the average reachable rate of the pre-networking. In step S101, different communication methods are used to pre-network the access node, and a better communication method is selected according to the networking result of each pre-networking.
In a specific embodiment, a better communication mode may be determined according to the number of nodes accessed in the pre-networking network, and specifically, the communication mode with the largest number of nodes accessed after the pre-networking network may be determined as the first communication mode; alternatively, the average reachable rate of each pre-networking network may be estimated, and the communication mode with the highest average reachable rate may be the first communication mode.
In another embodiment, appropriate weights may be set for the number of access nodes and the average achievable rate, respectively, a weighted sum may be obtained, and the weighted sum may be used as an index for selecting the first communication method, and specifically, the communication method with the largest weighted sum may be determined as the first communication method. The method for determining the first communication mode is very flexible, and can timely adjust the number of the access nodes and the weight of the average reachable rate according to the needs so as to meet the needs of communication networking in different occasions. For example, when networking is performed quickly, the weight of the number of access nodes can be increased, so that more nodes can be accessed after the networking is performed for the first time; during fast communication, the weight of the average reachable rate can be increased, so that the communication network obtained by networking can have higher communication speed.
Step S102: and networking the nodes to be accessed according to the first communication mode to realize the first networking. And (4) carrying out first networking by using the first communication mode screened out in the step (S101), wherein most of nodes to be accessed can be successfully accessed after the first networking. In a specific embodiment, the communication network after the first networking may be tested to screen out nodes with unreliable communication performance. Specifically, the communication reliability of each node can be tested in a mode of sending test data to each node for multiple times one by one; only nodes that can reliably transmit test data each time can be considered as reliable nodes. For a node with unreliable communication performance, the node should be disconnected from accessing the communication network through the first communication mode, and the node should be accessed again in the subsequent steps.
Step S103: and acquiring a network topology structure corresponding to the first networking. By the network topology structure, the accessed nodes and the communication mode among the nodes can be obtained after the first networking in the current stage. In addition, in the network topology, the type of the accessed node can also be shown. The communication nodes supporting various different communication modes are called as fusion nodes, and the fusion nodes comprise three types, namely physical layer fusion nodes, MAC layer fusion nodes and multimode fusion nodes. The physical layer fusion node means that different communication modes in the node are fused in a digital domain of a PHY (physical layer), and share one digital processing unit, but each communication mode has an analog processing unit of the communication mode. The MAC layer fusion node means that different communication modes in the node are fused in the MAC layer, and share one MAC layer, but each communication mode has its own PHY processing unit. The multimode fusion node refers to that various communication modes in the node have corresponding MAC and PHY. A node that supports only one communication means is referred to as a single communication node. Direct communication can be realized between the fusion nodes, and direct communication can be realized between the fusion nodes and a single communication node. The single communication nodes supporting different communication modes can not realize direct communication, but can realize mutual communication through the fusion node.
Step S104: and screening the unaccessed nodes in the nodes to be accessed according to the network topology structure. According to all nodes to be accessed before the first networking and the current network topology structure, the current nodes which are not accessed can be obtained.
Step S105: selecting any node in a network topological structure, controlling any node to search a corresponding neighbor node in the unaccessed nodes through neighbor node discovery messages, and accessing any neighbor node into the network topological structure by using a corresponding communication mode. The non-access node is a node which can not be accessed effectively by using the first communication mode, and can access the network by adopting any node which sends neighbor node discovery messages by using a corresponding communication mode according to the neighbor node discovery messages received by the non-access node. The networking result may be stored in the route adaptation module of each node in the form of a route information table. When each node has a data transmission requirement, the routing information table of each node is searched, and data transmission is completed according to the destination node and the communication mode indicated in the routing information table.
Alternatively, step S105 may be repeatedly executed until the nodes to be accessed all access the network topology.
The networking method fusing multiple communication modes provided by the embodiment of the invention checks the communication mode with the strongest current communication capability through pre-networking, and carries out networking for the first time according to the communication mode so as to realize the access of nodes as many as possible; for nodes which are not accessed after the first networking, neighbor nodes of all accessed nodes are searched in the nodes through various communication modes, the access of the neighbor nodes is realized, the advantages of various communication modes are favorably exerted, the deep integration and advantage complementation among various different communication modes are realized, the node access rate is improved, the problem of limited application range of a single communication mode is solved, and the requirements of communication objects supporting different communication modes on interconnection and intercommunication can be met.
In a specific embodiment, as shown in fig. 2, the step S105 in the networking method combining multiple communication methods can be implemented by the following steps:
step S201: selecting any node in a network topology;
step S202: judging whether the communication hop count corresponding to any node is smaller than a preset maximum hop count or not;
step S203: when the communication hop count corresponding to any node is smaller than the preset maximum hop count, controlling any node to send a neighbor node discovery message;
step S204: judging whether any node receives a corresponding feedback message;
step S205: when any node receives the corresponding feedback message, determining the corresponding node which is not accessed as the neighbor node of any node;
step S206: and connecting any node with any neighbor node through a corresponding communication mode.
Specifically, the master station may screen, hop by hop and node by node, whether the node can be accessed to the node. For example, several nodes of a first hop directly connected to the communication master station are screened, and the nodes are sequentially made to try to connect to the unaccessed node through any communication mode, and if the connection is successful, the unaccessed node accesses to the first hop node through the communication mode to become a second hop node in the network topology structure. Correspondingly, after the screening of the first hop node and the access of the subsequent nodes are completed, the screening and the access of the subsequent nodes to each second hop node can be completed in the same way, and so on until the communication hop count reaches the preset maximum hop count or all the nodes are accessed. In the embodiment of the invention, the purpose of presetting the maximum hop count is to control the communication speed of the communication network after networking, so that overlarge delay is avoided.
The networking method fusing multiple communication modes provided by the embodiment of the invention supports multi-hop communication, each hop can adopt different communication modes, and the networking method can be compatible with multiple different types of communication nodes and realizes flexible access of the communication nodes.
Due to the limitation of a single communication node in communication mode selection, in practical application, when any node and any one of the neighbor nodes are the single communication node, the single communication node is connected with the other node by using a communication mode corresponding to the single communication node. Because the fusion node is open in the communication mode selection, in practical application, it may be determined in step S206 whether the two communication nodes to be connected are both fusion nodes, and for the case that the two nodes to be connected are both fusion nodes, any communication mode may be used to connect the two nodes, and because the communication mode is not limited, the flexibility of node access is enhanced. For example, a communication mode with the highest communication rate may be selected to connect two fusion nodes to obtain a higher communication speed; the communication mode with the best stability can be selected to improve the reliability of communication.
The embodiment of the present invention provides another networking method fusing multiple communication modes, which includes steps S101 to S105 of the above networking method, and for avoiding repetition, details are not described herein again. As shown in fig. 3, in another networking method fusing multiple communication manners provided in the embodiment of the present invention, in step S102, a node to be accessed is networked according to a first communication manner to implement first networking, and the following steps are added between the step S103 and the network topology corresponding to the first networking:
step S301: judging whether the node which is not accessed after the first networking can be accessed in a communication mode different from the first communication mode;
step S302: and when the node which is not accessed after the first networking can be accessed in a communication mode different from the first communication mode, the node which is not accessed after the first networking is respectively accessed in the corresponding communication modes so as to realize the second networking. Correspondingly, in another networking method fusing multiple communication modes provided in the embodiment of the present invention, step S103 needs to be modified to: and acquiring a corresponding network topology structure after the second networking.
According to the networking method fusing multiple communication modes, after the first networking, the second networking is carried out by utilizing a communication mode different from the first networking, and the purpose that more nodes are accessed through a method for replacing the communication mode is achieved more quickly, and the networking efficiency is improved is achieved.
