Implementation method and system for high dynamic UAV ad hoc network routing protocol

Abstract

The invention relates to an implementation method and system for a high-dynamic unmanned aerial vehicle ad hoc network routing protocol. The routing protocol comprises the following steps of respectively acquiring a source node, a plurality of intermediate nodes and a destination node; generating a first RREQ message according to the source node; enabling the intermediate node to receive and process the first RREQ message, and update the first RREQ message to obtain a second RREQ message; enabling the destination node to receive and process the second RREQ message to generate an RREP message;and enabling the source node to receive the RREP message and add the information of the destination node into a local routing table. The routing protocol evaluates the life cycle of a path in a routediscovery process by taking the remaining time of a link and the remaining time of a route as the standard, the stability of the route discovery path can be improved, and the turn-off frequency of thepath is reduced to a certain extent in the high-dynamic topology change, and thus delay and expenditure brought by the re-starting route discovery process are reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method and a system for implementing a routing protocol of a highly dynamic unmanned aerial vehicle ad hoc network. Background technique [0002] With its unique flexibility, convenience and high efficiency, wireless network has become a rapidly growing field of communication in recent years, and it is also one of the important development directions. Among them, the Ad Hoc network has the following characteristics. Each node in the network can move independently and randomly; the network has the ability to dynamically reconfigure the route when the topology changes; In the case of a node failure, it does not affect the communication of other nodes; the independent network nodes form a network by themselves and do not depend on fixed communication facilities. These excellent characteristics make it occupy an important place in the field of civil and ...

[0004] However, it is no longer suitable for AODV to select the path with the least number of hops from the source node to the destination node in the high-speed motion UAV networking scenario. Because the UAV moves very fast, the previously selected path is easy to move to other locations. Cause path failure and need to restart the route discovery process, which will lead to increased network routing overhead and communication delay
