Aircraft ad hoc network method based on same-time same-frequency full duplex

Abstract

The invention relates to an aircraft ad hoc network method based on same-time same-frequency full duplex, and the method comprises the steps: installing a crystal oscillator clock circuit which is used for providing clock pulses on all to-be-networked aircrafts, enabling one aircraft to be called as a node, and carrying out the initialization; in the flight process of the aircraft, dynamic management of cluster heads and clusters in the ad hoc network is carried out, and dynamic access of nodes to the clusters is completed; on a public broadcast channel f0CN, the working state of a cluster head node is detected in real time, whether the cluster head is damaged or not is judged, and if the cluster head is damaged, a new cluster head is selected, and a cluster structure is updated; detecting whether routing failure and link interruption occur or not on a public broadcast channel f0CJ of inter-cluster communication, if the routing failure or the link interruption occurs, updating a routing table and a network topology, and effectively establishing a communication path; according to service requirements, whether communication is in-cluster communication or inter-cluster communication is judged, resources allocated to each node, channels used by the nodes and access protocols are determined, and it is ensured that in-cluster node information can be shared in real time and inter-cluster node information can be shared in a wide area.

Description

technical field [0001] The invention belongs to the technical field of wireless network and communication, and in particular relates to an aircraft self-organizing network method based on simultaneous and same-frequency full-duplex, in particular to a full-duplex intra-cluster communication method and a full-duplex inter-cluster communication method. Background technique [0002] Cooperative networking of aircraft is faced with the threat of complex electromagnetic interference and node destruction. At the same time, the real-time requirements for interactive information are extremely high, resulting in severely limited time-frequency resources. It is necessary to use simultaneous co-frequency full-duplex transmission waveforms with high spectral efficiency and low delay. Realize high bit rate and low delay for aircraft cooperative information interaction. In the design of the continuous wave radar system in the 1940s, the basic concept of simultaneous and same-frequency ful...

AI Technical Summary

Problems solved by technology

Traditional networking protocols suitable for half-duplex channels cannot utilize full-duplex channel resources at the same time at the same frequency, resulting in waste of resources and low spectral efficiency. At the same time, the anti-interference ability is reduced due to the inability to use interference-aware features

In addition, in terms of network construction, network management and routing selection are too simple, the network overhead is large and the flexibility is insufficient
