| environment | The application of Mobile Ad Hoc Networks to cattle monitoring has
the potential to increase the profitability of cattle production and
positively impact the everyday live of farm personnel. To realize
these possibilities, design of wireless protocols needs to be driven
by real experiences. The main research challenges are identifying and
refining realistic requirements for a MANET routing protocol and
designing such protocol. In order to address this, we performed
the field experiments at the University of Nottingham's Dairy Centre.
The purpose of these field experiments was collection of realistic
parameters necessary to develop and evaluate an adequate wireless
protocol. They included cattle movement and behavior monitoring
as well as distributing a questionnaire to the farm personnel and
researchers working on the farm. |

measurements were automatically collected by milking robots whenever a cow
was milked. |

| methodology | In the first field experiment we monitored two of the cows located in one of
the divisions of a modern dairy intended for about 100 animals. Cows can move
freely in the area with the feeder, water tank, resting bays and milking robots
available 24 hours a day.
We installed on the monitored cows two collars comprising a neck strap
and an aluminum instrument enclosure containing a Bluetooth GPS and
a Bluetooth enabled mobile phone.
Mobile phones were logging data from the GPS receivers including positions
and timestamps. All the cows in the dairy were wearing pedometers. Their
measurements were automatically collected by milking robots whenever a cow
was milked. The data collection started at 11:10. Both GPS receivers
worked until around 14:05.
Some of the collected measurements suggested that cows moved with speeds
impossible for them, which suggested GPS errors. Concurrently we were
filming the part of the dairy where the monitored cows were kept. We placed
the camera on the ramp above this area. This location offered the most
complete view but some parts of the area were obscured. GPS receivers and
filming were utilized only for the purpose of our field experiments.
Their utilization is not intended for the target monitoring system.
We repeated the previous experiment with five collars mounted on animals
and two cameras located at two different ramps to get a more complete view
of the area where the monitored cows were kept. We had GPS receivers
with better batteries than before and we were logging data about the precision
of logged locations. Monitoring started at 11:10. GPS receivers worked
until 18:24, 12:23 (probably jammed), 18:51, 15:09, 15:33. We received
the plan of the dairy and then captured the coordinates of the characteristic
locations on the plan using a handheld GPS receiver. |

DATE - date of the measurement
LAT - latitude

DOP (dilution of precision) is an indication of the effect of satellite geometry on the accuracy of the fix. It is a unitless number where smaller is better. For 3D fixes using 4 satellites a 1.0 would be considered to be a perfect number, however for over determined solutions it is possible to see numbers below 1.0.
