Luster: Environmental Monitoring Using Wireless Sensor Networks Presented by Maha M. Dessokey
The Main Idea Shrub are replacing grasslands and taking over Hog Island (and the world). Where are grasslands, what happened to them? Will we still have grass in X years? LUSTER (Light Under Shrub Thickets for Environmental Research) system, a typical Environmental Wireless Sensor Network (EWSN), is to investigate the use of WSNs for monitoring the effects of sunlight on shrub thicket.
The Main Achievements The main contributions of this work are: –LiteTDMA, a cluster-based, low-power TDMA MAC protocol that supports reliable communication, dynamic reconfiguration and node addition. –An overlaid, non-intrusive reliable storage layer that provides distributed non-volatile storage of sensor data for online query, or for later manual collection. –Hardware designs for spatially dense and reconfigurable light sensing
The Challenges New hardware to resist harsh environment. Deployment assurance. Reliable collection of data. Remote data uploading. In-network data backup. Robustness and self-healing.
An overview of Luster software architecture Key Software Components – Sensor queries and Data extraction. – LiteTDMA MAC protocol. – Reliable distributed storage. – Delay tolerant networking. – Deployment time validation –Backend server and database. – Run time validation and Self-healing
Deployment Experience Sensor nodes deployed in a cross, on a grid and along a tree branch Solar panel, Antenna and Stargate
