Implementation of herd management systems with wireless sensor networks

Abstract

The work summarises a study of the data communications requirements for agricultural livestock monitoring applications using wireless sensor networks (WSNs). Several design challenges are identified and analysed in depth based on actual global positioning system positioning data gathered from an actual herd of cattle. A wireless system including antennae diversity together with data downloads optimisation schemes utilising data collector and routers are developed and tested in a working farm environment. Two analysis metrics, connection availability and connection duration, are used to quantify the impact of cattle movement on network connectivity. The major contributions of this study stem from a definition of the communication issues in deploying animal monitoring platforms in free-ranging farm environments and the analysis and optimisation of the wireless data download performance using as the foundation knowledge gained from a series of working farm trials. Additionally, the data download protocols are designed particularly to treat animal movement. The results prove the viability of WSN-based solutions for livestock monitoring applications

Polarization diversity antenna with L-shaped slit for wireless sensor network

“…Figure 2 and Fig.3 show the correlation coefficient and the mutual coupling between two antennas, where correlation coefficient is calculated by (1). Due to the current distribution on the nonfeed antenna is decrease under the condition of l = 48 mm (0.16 0 ) and 54 mm (0.18 0 ), the correlation coefficient and the mutual coupling between two antennas decrease.…”

“…A diversity antenna is one of the key techniques in the system to reduce the effect by them and improve performance of the system [1].…”

Wireless indoor tracking of livestock for behavioral analysis

“…The position of the animal within the space and the tracking of livestock in indoor environments have been experimented on less, as the demands of accuracy for a useful application are strict. Research projects on this topic include [8] and [9].…”

Cattle monitoring system using wireless sensor network in order to prevent cattle rustling

“…Two data transport schemes are proposed to facilitate sending realtime data about an animal's status to the farm manager. Then two analysis metrics, namely connection availability and connection duration, are used to quantify the impact of cattle movement on network connectivity [13].…”
