Embodiment Construction

[0025] Such as figure 1 Shown is a large-scale ad hoc network routing method in open space, comprising the following steps:

[0026] Step 1, pre-initialization: the ad hoc network node sets a t_b timer, collects the HELLO message sent by the surrounding neighbor nodes during the timing period, and correspondingly understands the topology around the ad hoc network node itself, in order to send global LSU information.

[0027] Wherein, the LSU information is message information.

[0028] Step 2. Initialization: When the t_b timer expires, the ad hoc network node described in step 1 sends the global LSU information, and announces the link between itself and the surrounding neighbor nodes to other ad hoc network nodes in the ad hoc network Status information; after initialization, each ad hoc network node quickly completes convergence and obtains a topology diagram of the entire network.

[0029] Step 3: Entering an undetermined mode: after the initialization is completed, the a...

Abstract

The invention discloses a large-scale ad hoc network routing method in open space, comprising the steps of: 1. Pre-initialization: setting a t_b timer and collecting HELLO messages of neighboring nodes on the surrounding side during a regular period, and correspondingly understanding the surrounding of the ad hoc network node itself topology; 2. Initialization: When the t_b timer expires, the ad hoc network node sends the global LSU information, and announces the link status information between itself and the neighboring nodes on the surrounding side to other nodes in the ad hoc network; 3. Determine the mode, that is, the UNDEC mode; 4. Determine the working mode: after entering the UNDEC mode, the ad hoc network node determines the working mode to be adopted by itself; 5. Enter the working state: the ad hoc network node follows the determined working mode. working. The method of the invention is simple in steps, reasonable in design, convenient in implementation, high in intelligence and good in use effect, can perform adaptive routing under different network scales, and satisfies the optimization of minimum routing overhead.

Description

technical field [0001] The invention relates to a routing method, in particular to a routing method for large-scale ad hoc networks in open space. Background technique [0002] The air-ground broadband ad hoc network is mainly used to realize various medium and low-altitude aircraft, such as: helicopters, attack aircraft and unmanned aircraft, and multimedia and networked multimedia communications between these aircraft and ground vehicles and personnel. According to different actual needs, the scale of the air-to-ground broadband ad hoc network ranges from a small-scale network with dozens of nodes to a large-scale network with thousands of nodes. Therefore, the routing of the air-ground broadband ad hoc network must be able to adapt to different network scales to meet the optimization of the minimum routing overhead. [0003] At present, there are mainly the following two types in ad hoc network routing technologies: First, active routing: active routing is also called ta...
