1. 1 Floodnet Group 14 FloodNet Team 14: Darko Matovski David Sansome Sarmad Mehrbod Thomas York Vaidotas Zudovas Presentation Overview: Ubiquitous computing Existing flood warning systems About Floodnet How it works Software used

2. 2 Group 14 FloodNet  Computers integrated with the environment instead of being distinct objects.  Allows users to interact with technology more naturally.  Adaptive to environment and needs of users.  Has very widespread applications, one of which is Floodnet. Ubiquitous computing

3. 3 Group 14 FloodNet Existing flood warning systems Present techniques for monitoring water levels use traditional recording systems such as data loggers, and typically involve manual data collection. This imposes limitations on the usefulness and timeliness of the conclusions drawn from analysis of the data.  Contain data loggers that must usually be collected in person  Slow response times to flood warning signs Problems:

4. 4 Group 14 FloodNet Introduction to Floodnet  Wireless nodes placed in an area prone to flooding.  The nodes take samples and communicate with each other and a central database.  Decisions can be made more quickly.  Nodes are solar powered and designed to minimize power consumption.

5. 5 Group 14 FloodNet Floodnet – How it works Wireless network consisting of nodes - boxes of electronics - that store regularly sampled information about the local environment. The system collects data over a period of time and constantly analyses it. If critical changes are recorded, data is sent to a central gateway node, which evaluates, generalizes and sends data to a remote computer grid, where the decisions are made.

7. 7 Group 14 FloodNet Summary  Wireless communication.  System analyses the data itself.  Varies sample rate depending on status of the environment.  Varies rate of data transmission to reduce power.  Nodes powered by solar cells. Floodnet's key features:

9. 9 Group 14 FloodNet General lessons learnt  Establishing firm team roles enabled us to make better use individuals' strengths and abilities. Also less time was wasted in task assignment.  Balancing group and independent work helped increase efficiency.  Setting deadlines and having the group enforce them was useful.  Working over christmas was found difficult by all group members.  Mind maps were useful for forming ideas, but they proved difficult to convert to structured text.
