Problems solved by technology

In view of the above-mentioned linear topology wireless ad hoc network deployment scenario, the existing wireless ad hoc network routing technology is applied to the linear topology wireless ad hoc network, the collection and maintenance of routing topology information, routing path query calculation In the implementation method of sending a large number of messages, it increases the risk of communication congestion for a linear topology network that has few routing paths and is sensitive to the capacity of the communication channel, which is not conducive to providing a high-capacity network.
In addition, deleting temporarily unused paths leads to a new process of collecting and maintaining routing topology information and routing path query and calculation when there is a need for information forwarding again, resulting in low routing efficiency, increased routing delay, and reduced user experience quality

Embodiment 2

[0070] Embodiment 2 is also a linear topology wireless ad hoc network applied in the production process of a roadway in a mine:

[0071] Compared with Example 1 in this embodiment, the main difference is the difference in the routing mode in the embodiment step 2b, and the routing mode in the present embodiment is as follows:

[0072] The specific route forwarding can adopt the first wireless node that receives the wireless communication data packet to carry the wireless node of the required path in the forwarded wireless communication data packet with the result of the routing path inquired, and the wireless node that receives the wireless communication data packet According to the information carried in the data packet, it is directly forwarded to the next-hop wireless node until the wireless communication data packet is forwarded to the destination wireless terminal. The specific sending methods are as follows: Figure 10 shown.

Embodiment 3

[0075] Embodiment 3 is applied to the linear topology wireless ad hoc network network during the construction of railway tunnels through mountains:

[0076] Embodiment 3 is compared with Embodiment 1. The main difference is that the generation of the routing table including the optimal routing path information is not generated in real time after receiving the routing forwarding requirements, but after obtaining the network routing topology information (ie: wireless node topology relationship table) and the association table between the wireless node and the wireless terminal), a dynamic local routing table is generated based on the information based on the shortest route algorithm or other routing algorithms, and the routing table includes the best routing path records from the wireless node to each wireless terminal, wherein The dynamic maintenance and update of the information is processed synchronously with the update of the network routing topology information (that is, the...

Embodiment 4

[0086] Embodiment 4 is applied to the linear topology wireless ad hoc network network during the construction of railway tunnels through mountains:

[0087] The present embodiment contrasts embodiment 3, and main difference is the difference on the routing mode in the embodiment step 2b, and the routing mode in the present embodiment is as follows:

[0088] The specific route forwarding can adopt the first wireless node that receives the wireless communication data packet to carry the wireless node of the required path in the forwarded wireless communication data packet with the result of the routing path inquired, and the wireless node that receives the wireless communication data packet According to the information carried in the data packet, it is directly forwarded to the next-hop wireless node until the wireless communication data packet is forwarded to the destination wireless terminal. The specific sending methods are as follows: Figure 10 shown.

Abstract

The invention relates to a routing method for a linear topology wireless ad hoc network, and belongs to the technical field of wireless communication network routing. The method comprises the following steps of generating a static topological structure relation table between wireless nodes in each wireless node of a network; in the network operation process, enabling each wireless node to generatea dynamic wireless node and wireless terminal association table based on the real-time state and dynamically maintain the association table; after receiving the information that a wireless communication data packet needing to be forwarded, enabling each wireless node to calculate and forward the shortest routing path to a target wireless terminal according to the shortest routing path of the target wireless terminal in a local routing table; and when the target wireless terminal moves and is associated with a new wireless node or the link between the wireless nodes is interrupted and the liketo influence the effectiveness of the shortest routing path, deleting the corresponding record in the local routing table, and adding the record in the local routing table. The method has the advantages of being low in network load, high in routing efficiency and low in hardware performance requirement, and being easy to implement.

Description

technical field [0001] The invention belongs to the technical field of wireless communication network routing, and particularly proposes a network routing method of a linear topology wireless ad hoc network. Background technique [0002] The wireless ad hoc network is a temporary multi-hop autonomous system composed of a group of mobile wireless nodes with wireless transceiver devices. Center, strong invulnerability and other characteristics. There are many types of topological structures of wireless ad hoc networks, including tree, mesh, and line. Among them, the linear topology wireless ad hoc network is a special tree topology, which refers to the root wireless node as the starting layer wireless node, each layer has a wireless node, and multiple wireless nodes are cascaded layer by layer, which can be implemented in a small number of In the case of wireless nodes, long-distance network coverage can be achieved, such as figure 1 The shown is the linear topology topolog...
