Faculty of Engineering. Dept. of Electrical and Electronic Engineering.ENGLISH ABSTRACT: The real-time monitoring and collection of agricultural sensor data have been a challenge faced by farmers around the world. This thesis explores the design of a system to make the collecting and viewing of this vineyard telemetry data easy and robust. An Ad-Hoc Wireless Sensor Network was designed and built to collect data specifically from vineyard based environments, and transmit the data from the network to a database and dashboard where it can be analysed and viewed by the farmer. The network uses a mesh networking protocol to extend the range of the network beyond the range of a single node-node link. A network protocol based on AODV was developed to handle the routing of information within the WSN. Alongside the physical nodes, an algorithm was designed to aid in the optimal placement of gateway nodes within an existing network, as well as the optimal placement of all nodes given the practical considerations that need to be taken into account when installing nodes in the real-world environments.
