Embodiment Construction
[0078] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0079] See image 3 , which shows a method flowchart of a method for establishing a multi-hop network provided by an embodiment of the present invention. The method for establishing a multi-hop network may include the following steps:
[0080] Step 101, determine the agent node number N of this network, N is the integer greater than 1;
[0081] In order to avoid the problem of low communication efficiency caused by the communication with all nodes being forwarded through the same root node, the method provided in this embodiment selects multiple proxy nodes to share the forwarding task of the root node when building a multi-hop network.
[0082] Specifically, the number of proxy nodes in the network may be determined according to pre...

The invention discloses a method for establishing a multi-hop network, and belongs to the field of short-distance wireless communication. The method comprises the following steps of: determining a proxy node number N of a network, wherein the N is an integer more than one; selecting N nodes as proxy nodes from disconnected nodes; and establishing connection with the selected proxy nodes so as to initiate multi-hop network establishment from the proxy nodes, wherein the multi-hop network consists of a plurality of proxy nodes, and is a wireless network in which the nodes communicate with one another by information multi-hop forwarding. According to the method, a plurality of proxy nodes are determined, a plurality of proxy nodes initiate multi-hop network establishment, and forwarding tasks during communication between the proxy nodes with each node are shared by a plurality of proxy nodes, the phenomenon that only a root node bears data forwarding tasks during communication between network establishing equipment and all nodes is avoided, and the aim of improving communication efficiency is fulfilled.
Description
technical field [0001] The invention relates to the field of short-distance wireless communication, in particular to a multi-hop network building method, building equipment and nodes. Background technique [0002] In order to overcome the shortcomings of short wireless transmission distances in short-distance wireless communication applications such as Bluetooth and WiFi, a multi-hop network is usually used to expand the coverage of wireless communication. Specifically, see figure 1 The schematic diagram of node multi-hop is shown, in which node A and node B can see each other, node B and node C can see each other, but node A and node C cannot see each other; after establishing a multi-hop network, the data sent by node A can pass through node B forwards to node C to achieve the purpose of communication between node A and node C. [0003] Take the application of Bluetooth multi-hop network as an example, please refer to figure 2 A multi-hop network structure diagram is s...
