Virtual fencing applications: Implementing and testing an automated cattle control system
Computers and Electronics in Agriculture, 2007 Managing livestock movement in extensive systems has environmental and production benefits. Currently permanent wire fencing is used to control cattle; this is both expensive and inflexible.

Drone Virtual Fence Using a Neuromorphic Camera
International Conference on Neuromorphic Systems 2021, 2021Neuromorphic cameras are well suited to detect the motion of propellers (blades) on Unmanned Aerial Systems (UAS), or drones. In this paper, we introduce the concept of a virtual fence which is a low-cost networked situational awareness device to quickly alert that a drone has entered the zone.

Research platform for cattle virtual fences
2020 IEEE International Conference on Industrial Technology (ICIT), 2020Prior work in virtual fences has proposed different schemes to keep cattle confined within a remotely configured perimeter. These techniques share a common pattern that consists in placing an electronic device in the animal capable of applying a stimulation when it approaches the pre-established limits.

Virtual Fence for a Surveillance System
2009This paper presents a method for defining one or more virtual restricted zones within a surveillance area which is observed with stereo cameras. When an object enters a restricted zone, the system highlights the object shown in the monitoring screen or triggers other devices to produce a visual or auditory alarm. The proposed method works by extracting

Dynamic Virtual Fences for Controlling Cows
2006A virtual fence is created by applying an aversive stimulus to an animal when it approaches a predefined boundary. It is implemented by a small animal-borne computer system with a GPS receiver. This approach allows the implementation of virtual paddocks inside a normal physically-fenced paddock.

A virtual fence for animals management in rangelands
MELECON 2008 - The 14th IEEE Mediterranean Electrotechnical Conference, 2008Protecting biotopes and maintaining biodiversity are ecological aims highlighted in European policies. Grazing systems which have to adapt to these new constraints require new fencing technologies. Here we present a virtual fence based on an electromagnetic coupling principle.

107 Use of virtual fences to co-fence two groups of cattle with a shared virtual boundary
Journal of Animal ScienceAbstract Virtual fencing (VF) provides cattle producers with an opportunity to manage grazing more intensively without the need to build physical fences. Cattle are fitted with GPS equipped collars and are kept within producer determined boundaries through the use of audio and electric stimuli.

From Robots to Animals: Virtual Fences for Controlling Cattle
The International Journal of Robotics Research, 2006We consider the problem of monitoring and controlling the position of herd animals, and view animals as networked agents with natural mobility but not strictly controllable. By exploiting knowledge of individual and herd behavior we would like to apply a vast body of theory in robotics and motion planning to achieving the constrained motion of a herd.

Virtual fencing – past, present and future1
The Rangeland Journal, 2007Virtual fencing is a method of controlling animals without ground-based fencing. Control occurs by altering an animal’s behaviour through one or more sensory cues administered to the animal after it has attempted to penetrate an electronically-generated boundary.
