Embodiment 1

[0075] A specific embodiment of the present invention discloses an Ad Hoc network virtual backbone node identification system, such as figure 1 As shown, it includes a receiving unit, a signal processing unit, a network physical topology inference unit and a backbone node identification unit connected in sequence, and the four are integrated and installed on the vehicle platform.

[0076] The receiving unit is used for receiving signals in the working frequency band of the Ad Hoc network.

[0077] The signal processing unit is used to preprocess and detect the signals in the working frequency band of the above-mentioned Ad Hoc network, identify the nodes in the Ad Hoc network, and locate the nodes in the Ad Hoc network by radio positioning methods, and obtain the number of nodes and node position information and node deployment area size.

[0078] The network physical topology inference unit is used to obtain the important communication distance according to the above-mention...

Embodiment 2

[0087] Optimizing on the basis of Example 1, such as figure 2 As shown, the receiving unit includes an antenna and a wideband receiver connected in sequence.

[0088] The wideband receiver is used to receive the signals in the working frequency band of the Ad Hoc network through the antenna, and transmit the received signals in the working frequency band of the Ad Hoc network to the signal processing unit. Wherein, through the antenna, the intensity of the received signal (the signal in the working frequency band of the Ad Hoc network) can be enhanced, and through the broadband receiver, the wide spectrum characteristic of the received signal can be realized.

[0089] Preferably, as image 3 As shown, the signal processing unit includes a preprocessing module, a node information detection device, a radio positioning device and a node information statistics device connected in sequence.

[0090] The preprocessing module is used to perform signal preprocessing on the received...

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an Ad Hoc network virtual backbone node identification system. Background technique [0002] Ad hoc network is a special kind of wireless network. Different from general wireless networks, Ad hoc networks have the characteristics of rapid deployment, no need to set up network facilities, and nodes in the network can move according to needs, making it widely used in civil and military communications. [0003] At present, the security of the Ad hoc network has received more and more attention. Among them, the identification of the backbone nodes in the Ad hoc network is of great significance. Specifically, it is beneficial to protect the backbone nodes in the network in a targeted manner. At the same time, the performance of the entire network can be greatly improved by improving the computing power and information processing power of the backbone nodes. [0004] Existing t...
