Motivation
Water and environmental monitoring todayOften requires periodic field visits for data collectionNetworking of sensor / instruments infeasible or expensiveNo infrastructure in remote locations
Satellite networks expensive; cellular data networks unavailable“BYON” : bring your own network challenging
Challenge: Design low-cost easily-deployable wireless sensor networks for real-time data collection from the field

Technology Trends
Low-cost wireless network technologies availableWiFi-based networks are the most common exampleMesh-based deployment at field siteBackhaul via point-to-point long-distance links
Directional antennas: Wifi links can stretch to 10s of kilometers!Other wireless radios: Xtend, XE1205 also give long range
Energy-efficient sensor platforms availableLow-power microcontrollers, high-capacity flash storageBattery-powered with lifetimes of weeks to monthsCan be solar or wind-powered!

Summary
It is possible to inexpensively network field sensors for water monitoring.
Deployments in environments without infrastructure is possible
Easily deployable wireless sensor networksSelf-configuring: deploy and go
Use solar – wind power to enhance batter life of sensor nodes
