Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] The main technical idea of ​​the present invention is such:

[0042] All nodes complete the network access authentication process by sending a network access request packet to the central control node and receiving the network access approval packet sent back by the central control node; obtain the location information of other nodes by periodically sending and receiving hello packets; periodically check the location information of a node Whether the node has not been updated for a long time to determine whether the node has withdrawn from the network; a new central control node is selected through the selection rules of the new central control node after the central control node withdraws from the network, to solve the problem of central control node failure and withdrawal from the network, multiple central control nodes Convergence to a unified...

Abstract

The invention discloses an air Ad hoc network topology awareness and maintenance method, and mainly solves the problems that the network robustness is poor, the network is likely to fall into disorder after a center control node is failed, and multiple center control nodes appear in segmentation and combination processes of topology, in an air Ad hoc network topology control method. The implementation process of the air Ad hoc network topology awareness and maintenance method is as follows: all nodes access the network to obtain position information of other nodes; after any node exits from the network, other nodes can delete the information of the exited node in time; when the network runs regularly, only one center control node exists, after the center control node exits from the network, one node which firstly detects the information about exit of the center control node starts to compete for the identity of new center control node, the node with smallest IP of all the nodes in the competition finally becomes the new center control node; in the process that the network topology is segmented or combined, each independent network maintains one center control node. The method improves a topology control function of an air Ad hoc network, and can be used for network topology awareness and maintenance of the air Ad hoc network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an air ad hoc network topology perception and maintenance method, which can be used in the air ad hoc network. Background technique [0002] In the wireless ad hoc network in the air, to solve the problem of network topology perception and maintenance, there are usually two strategies: centralized and distributed. Although the distributed network topology perception and maintenance strategy is simple to operate, it is often difficult to perceive the global topology of the network. It is not comprehensive enough, and due to the lack of a dedicated central control node to be responsible for authenticating new nodes entering the network, there are major problems in its security. Compared with the distributed strategy, the centralized network topology perception and maintenance strategy can better manage the network topology and has higher security in the authenticatio...
