Transcript of Wireless Network For Sensors

Advantages Network Layout Wireless Network for Sensors The Project
The Samford Ecological Research Facility currently captures wildlife acoustic data.
Currently the sensor project is implemented with 3G technologies. This 3G implementation
has shown a few major downsides and thus has provided an opportunity to develop a better and more
cost effective solution.

This project is to design a wide area wireless network for these sensors. After comparing and contrasting
many different networking types a Wi-Fi mesh solution provided the highest reliability and network coverage.
ABOUT SERF SERF is located in the Samford Valley, a 25 minute drive north west from Gardens Point Campus in Brisbane, Queensland, Australia. The objective of this property is to provide QUT with a site specific, fully controlled research base for a range of natural science, engineering, built environment, and educational programs in areas pertaining to urban development and its impact on the ecosystem.

70% of the 51 hectare property is covered with vegetation and provides a natural laboratory for research.

Wireless coverage over the majority of the Samford site.
Ability to change the location of the wireless acoustic sensors easily.
Lower ongoing costs.
Internet access for researchers.

A full Wi-Fi mesh provides one major benefit which justifies an upgrade of the current network. The on-going data costs for 3G systems at this current time are quite high and a full Wi-Fi implementation would eradicate these costs.
One extra benefit is that more sensors can be easily deployed due to the large coverage area. This coverage also allows researchers with a Wi-Fi device to easily connect to the internet anywhere on the property.

The Network There are many different types of topologies that could be used at the Samford site. Each of these topologies has advantages and disadvantages such as redundancy or a high cost of implementation.

The first implementation that was looked at was the point-to-point implementation where each link connects directly to another link to form a continuous connection from the house to the acoustic sensor (see Image 1.0).

The advantage of using this topology is the low cost associated with the implementation; however this topology has no redundancy built into its design and is therefore prone to failure.

The second topology that was looked into was a partial mesh topology (see Image 1.1); this implementation has a high level of redundancy and can sustain several points of failure before losing any data.

The recommended implementation is the partial mesh since it has the greater redundancy however to achieve this topology requires a greater amount of antennas and routers. Hardware Required Linksys WRT54GL
RadioLabs Backfire Antenna Setup The implementation of the network can be done in a couple of iterations starting with the point to point and expanding the network to incorporate a partial mesh implementation. Hardware requirements are reduced in the initial stages of the project.
