Problems solved by technology

[0004] However, since each node in the Ad Hoc network can move freely, during the communication process between the first node and the second node, the first node or the second node is no longer in the antenna coverage area of ​​the other party, thus causing the first node to communicate with the second node. The communication quality of the second node is poor or even unable to communicate normally, and the communication reliability is low

Embodiment 1

[0035] refer to figure 1 , shows a flow chart of steps of a multi-beam antenna networking method in an embodiment of the present invention. Specific steps include:

[0036] Step 101, establishing a communication link with a first node, and determining a first antenna unit for communicating with the first node.

[0037] In order to ensure that the second node can communicate with the first node as a neighbor node, the second node may establish a communication link for communicating with the first node, and determine a first antenna unit for communicating with the first node.

[0038] The second node may send a communication link establishment broadcast message carrying the node identifier of the second node through any antenna unit, and when the first node receives the communication link establishment broadcast message, it sends the first node to the second node The communication link establishment feedback message of the node identifier of the node, when the second node rece...

Embodiment 2

[0054] refer to figure 2 , shows a flow chart of steps of a multi-beam antenna networking method in an embodiment of the present invention. Specific steps include:

[0055] Step 201, based on the arrangement of the antenna coverage areas of multiple antenna units, the second node sends a communication link establishment broadcast message through each antenna unit in a counterclockwise order, and the communication link establishment broadcast message carries the second node The node identifies and transmits the transmission power of the communication link establishment broadcast message.

[0056] In order to avoid the problem of discovering some nodes and establishing communication links caused by the second node missing scanning in certain antenna coverage areas, and the problem of reduced communication efficiency that may be caused by too frequent scanning of certain antenna coverage areas , and avoid the need for prior information of neighbor nodes to establish a communic...

Embodiment 3

[0090] refer to Figure 4 , shows a structural block diagram of a multi-beam antenna networking device in an embodiment of the present invention. The multi-beam antenna networking device includes:

[0091] An establishment module 401, configured to establish a communication link with the first node, and determine a first antenna unit for communicating with the first node;

[0092] A search module 402, configured to receive communications sent by the first node through the first antenna unit and at least one second antenna unit respectively during the process of communicating with the first node through the first antenna unit message, among the first antenna unit and the at least one second antenna unit, search for the antenna unit with the highest received power, where the second antenna unit is any antenna unit in the antenna array except the first antenna unit;

[0093] The switching module 403 is configured to switch to the found antenna unit to communicate with the first...

Abstract

The invention relates to the technical field of communication, and provides a multi-beam antenna networking method and device. The method comprises the following steps: establishing a communication link with a first node, and determining a first antenna unit used for communication with the first node; during the process of carrying out the communication with the first node through the first antenna unit, receiving communication messages sent by the first node respectively through the first antenna unit and at least one second antenna unit, and searching for the antenna unit with the larger receiving power between the first antenna unit and the second antenna unit, wherein the second antenna unit is any antenna unit in an antenna array other than the first antenna unit; and if the antenna unit obtained through the searching is not the first antenna unit, switching from the first antenna unit to the antenna unit obtained through the searching for the communication with the first node. The method and device provided by the invention has the advantage that the communication reliability is higher.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a multi-beam antenna networking method and device. Background technique [0002] With the development of communication technology, a variety of communication methods have been widely used, which provides convenience for human production and life. Among them, the Ad Hoc network occupies an important position in the communication technology because it does not require fixed basic equipment, all nodes in the network can be independently constructed, maintained and managed, and has strong anti-interference ability and survivability. AdHoc network is a multi-hop, centerless, self-organizing wireless network, also known as multi-hop network, infrastructure-free network or self-organizing network. Nodes in this network usually have multi-beam antennas, resulting in multiple sharp beams, each of which can cover a specific airspace, ie a different antenna coverage area. ...
