Method of self-organizing network directed route in air

Abstract

The invention discloses a method of a self-organizing network directed route in the air. The problems of being poor in invulnerability, roundabout in route, bad in link reliability, free of high priority level business service quality guarantee and low in network throughput in the method of a self-organizing network route in the air are mainly solved. The realization process is that all nodes obtain the position information of all other nodes by receiving a hello package; when a data package arrives, a current node finds out a next hop node according to a single hop communication distance fallback mechanism and a directed route strategy, inserts the data package into a sender array by delaying different time according to a priority level, and then sends the data package out; if the next hop node does not exceed the multi-package receiving capacity of a media access control (MAC) layer in the process of receiving the data package, receiving of the data package is successful; and if the node is not a destination node, the node is used as the current node, the above process is repeated until the destination node is reached. The method of the self-organizing network directed route in the air improves the route performance of a self-organizing network in the air, and can be used in the route process of the self-organizing network in the air.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an air ad hoc network directional routing 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 routing, there are usually several routing strategies such as active, passive, and geographic location information-assisted, among which the geographic location information-assisted routing strategy uses the geographic location information of nodes in the network to Looking for routes, the number of routing hops is small, the delay is low, and the overhead is relatively small, which greatly improves the efficiency of route finding, so it is widely used. [0003] With the development of satellite positioning technology, it is becoming easier for a node to obtain the geographical location information of itself or other nodes in the network, but in some special application fields...

AI Technical Summary

Problems solved by technology

For the self-organizing network in the air with high node movement speed, the connection relationship between nodes changes rapidly. Sometimes the previous hop node selects the next hop node within the single-hop communication distance by calculating the location information, and the next hop node A data packet is sent, but due to the long distance between nodes, the data packet needs to experience a large propagation delay to reach the next hop node, and when the node moves at a high speed, the next hop node within this propagation delay It is very likely that it has moved beyond the single-hop communication distance of the previous hop node, resulting in unreachable data packets and packet loss

In addition, since the hello packet for maintaining location information is sent periodically, there is also an error in the judgment of the previous hop node on the current location of the next hop node, which increases the probability of unreachable data packets.
