Example Embodiment

[0013] The present invention will be described in detail below in conjunction with the drawings and specific implementations:

[0014] figure 1 It is a block diagram of a wireless link backup scheme based on ad hoc network of the present invention, such as figure 1 As shown, a wireless link backup scheme based on ad hoc network adopts a multi-hop network, using wireless ad hoc network network, any wireless device node can act as a base station and router at the same time, and each node in the network can send and receive Signal, each node can communicate directly with one or more peer nodes. Compared with the traditional switched network, the wireless Mesh network removes the wiring requirements between nodes, but still has the redundancy mechanism and rerouting function provided by the distributed network. Utilizing the features of wireless Mesh technology for automatic discovery and fast rerouting, the Mesh network also allows the terminal to switch quickly under high-speed m...

Abstract

The invention relates to a wireless link backup scheme based on an ad-hoc network. The implementation principle is as follows: a multi-hop network is adopted, the wireless ad-hoc network is adopted, any wireless device node can serve as a base station and a router at the same time, each node in the network can send and receive signals, each node can directly communicate with one or more peer nodes, a remote control communication scheme of E1 and a kilomega port based on a wireless ad-hoc network device is achieved, the wiring demand among the nodes is removed by a wireless Mesh network, but a redundancy mechanism and a re-routing function provided by a distributed network are still required, the features of automatic discovery and fast rerouting of the wireless Mesh technology is utilized, the Mesh network also allows the terminal to quickly switch during high-speed moving in the network, the highly flexibly ad-hoc network topology not only supports point to point and point to multipoint, but also makes it possible for multipoint to multipoint centerless ad hoc network.

Description

technical field [0001] The invention relates to a wireless ad hoc network link backup scheme, in particular to a wireless link backup scheme based on the ad hoc network. Background technique [0002] In recent years, my country's mobile communication industry has been well developed, and relatively complete mobile communication networks have been established in most areas. However, due to reasons such as earthquakes, floods, lightning strikes, and man-made sabotage, the communication of the mobile base station is often interrupted. Through the statistics of previous major natural disasters and the reasons for the interruption of mobile base station communication in daily maintenance, it is found that the power supply system and ground transmission lines are most vulnerable to damage. The power supply system can improve the support capability by increasing the capacity of the battery, extending the working time or preparing mobile oil generators for free. The ground transmi...
