Embodiment Construction

[0083] The present invention will be further described below in conjunction with the accompanying drawings.

[0084] figure 1 with 2 The changes of node height and flight phase are described respectively, and the specific implementation methods are as follows:

[0085] 1. Before time t1, an aircraft node is in a dormant state, and its altitude is 0.

[0086] 2. At time t1, the aircraft node turns on the network device, and the system assigns the node identifier i to it. From t1 to t2, node i is waiting to take off, that is, it is in the waiting stage, and its altitude is 0.

[0087] 3. At time t2, node i is ready to take off. From t2 to t3, node i is in the take-off stage, and its altitude change law is according to figure 1 shown.

[0088] 4. At time t3, the flying height of node i reaches the cruising height h, enters the cruising stage, and its height remains at the cruising height.

[0089] 5. At time t4, node i is ready to land. From t4 to t5, node i is in the l...

Abstract

The invention relates to a topology construction and internet access method for an aviation ad-hoc network. In the method, a flight process is divided into five stages including a dormancy stage, a waiting stage, a take-off stage, a cruising stage and a landing stage; a corresponding topology construction and data transmission strategy is provided for a flight node in a specific flight stage, wherein a waiting node is used as a connection point between an ad-hoc network in the air and a ground network, passively accepts network access requests of other nodes, and is mainly responsible for data relay; on one hand, a take-off node rapidly establishes a link information table; on the other hand, the take-off node accepts a request of the waiting node, carries data of the ground network, and rapidly diffuses data of the ground network in the ad-hoc network in the air; a cruising node regularly updates the link information table, and selects the optimal and backup link to perform data exchange in the air according to a link distance and the link duration; and a landing node rapidly forwards the data of the network in the air to the waiting node, and finally forwards the data into the ground network. By means of the topology construction and internet access method for the aviation ad-hoc network disclosed by the invention, fully connected topology can be rapidly formed; and communication between the aviation ad-hoc network and the ground network is realized.

Description

technical field [0001] The application of the present invention relates to the topology discovery and construction process of the aeronautical ad hoc network, in particular to an effective topology update method in the aeronautical ad hoc network to maintain the stability and reliability of the network. Aiming at the aviation self-organizing network, the present invention proposes a network topology construction and Internet access method based on fast Unicom support and flight phase, which helps to solve frequent topology changes and network problems caused by large-scale scenarios and fast moving nodes. Instability problems, and can make full use of the characteristics of each flight stage of the aircraft for data transmission, improve the communication quality of the aviation self-organizing network, and provide an important topology basis for the design and research of its upper layer protocol, which belongs to the field of network communication technology.
