OLSR protocol black hole attack method for unmanned aerial vehicle ad hoc network

Abstract

The invention discloses an OLSR (Optimized Link State Routing) protocol black hole attack method for an unmanned aerial vehicle ad hoc network. The problem that an existing black hole attack method cannot be applied to a high-mobility drone ad hoc network is solved, the formation and the motion trail of the drone are changed, and finally the purpose of obtaining the network control right is achieved. The method comprises the following implementation steps that: an execution node calculates a node in a network center in an area through a routing table; the execution node reaches the transmission range of the central node through the time delay information transmitted by the data packet; the execution node sends a large number of Hello message packets of which the IP addresses are randomly modified to the central node to occupy the position of the central node; and node tampering is executed or the data packet in the network is discarded, and black hole attack is performed on the network. According to the method, the motion trail of the unmanned aerial vehicle ad hoc network can be drastically changed, the attack effect is good, the network is greatly damaged, and the method has obvious advantages in the aspects of changing the formation and the motion trail of the unmanned aerial vehicle, obtaining the control right of the network and the like.

Description

technical field [0001] The present invention relates to the technical field of mobile multi-hop ad hoc networks, in particular to an attack method for unmanned ad hoc networks, specifically an OLSR protocol black hole attack method for unmanned ad hoc networks, which can be used to attack unmanned The machine-ad hoc network conducts efficient attacks, changes the trajectory of the drone, and obtains network control. Background technique [0002] After nearly a hundred years of development, from the 1920s to the present, drone technology has attracted widespread attention. Unmanned Aerial Vehicle (UAV) is an aircraft managed by a control station (including remote control and autonomous flight), also known as Remotely Piloted Aircraft. However, due to the bottleneck of a single UAV performing tasks such as reconnaissance and target attack, organizing multiple UAVs with different functions is an important way of combat. Therefore, multi-UAV collaborative technology has become...

[0006] Purpose of the invention: In view of the above problems, the present invention proposes an OLSR protocol black hole attack method for UAV Ad Hoc Networks. This method makes the execution node approach and attack the central node first, thereby occupying the position of the central node, and then attacks the network. Black hole attack to solve the problem that the existing black hole attack cannot be applied to the high-mobility UAV ad hoc network, and cause greater damage to the network
