4. 4/30/033 Introduction  Habitat monitoring represent a class of sensor network applications with enormous potentials benefits for scientific communication and society  The sensor nodes are more efficient in providing localized measurements and detailed information of local processing and storage allows sensor nodes to perform complex filtering and triggering functions.  The ability to communicate allows to cooperate in performing more complex tasks, like statistical sampling, data aggregation, and status monitoring.

5. 4/30/034 Introduction Contd.  The computing and networking capabilities allow sensor networks to be reprogrammed or retasked after the deployment.  The impact of sensor networks for habitat and environmental monitoring will be measured by their ability to enable new applications and produce new results other wise too difficult to realize

6. 4/30/035 Need for Habitat Monitoring  Researchers in the life sciences are becoming increasingly concerned about the potentials impacts of human presence in monitoring plants and animals in field conditions.  A disturbance can seriously reduce or even destroy sensitive populations by increasing stress, reducing breeding success, increasing predation, or causing a shift to unsuitable habitats.  Disturbance effects are of particular concern in small island situation, where it may be physically impossible for researchers to avoid some species on an entire population.  So, sensor network deployment may represent a substantially more economical method for conducting long-term studies than traditional personnel-rich methods

7. 4/30/036 System Architecture The designed architecture is a tiered architecture The basic units in the design are :-- 1.Sensor nodes 2.Sensor node gateway 3.Base Station 4.Sensor Patch

9. 8 Implementation Strategies  Sensor Network Node  Sensor Board  Energy Budget  Sensor Deployment  Base Installation  Database Management System

10. 4/30/039 Sensor Network Node  In this deployment, they have used UC Berkeley motes as the sensor nodes.  The latest family of the family, called Mica[11]

11. 4/30/0310 Sensor Board  To provide relevant measurements to scientists, they have designed and manufactured an environmental monitoring sensor board  This weather board includes temperature, photo resistor, barometric pressure, humidity, and passive infrared sensors.

12. 4/30/0311 Energy Budget  Many habitat monitoring applications need to run for nine months.  Mica runs on a pair of AA batteries, with are typically 2.5 amps.  The application chooses how to allocate this energy budget between sleep modes, sensing, local calculations and communications.  We need budget our power with respect to the energy.

13. 4/30/0312 To estimate of what is possible on a Mica mote with a pair AA batteries, we tabulated the costs of various basic operations in this table.

14. 4/30/0313 Sensor Deployment The wireless sensor network was deployed on July 2002

15. 4/30/0314 Base Station Installation  It provides remote access to the habitat monitoring networks, the sensor network patches is connected to the internet through a wide area link.  It is considered as a turnkey system, since it needs to run unattended. Database Management  The base station currently uses Postgres SQL database.

16. 4/30/0315 Current Results  32 motes are deployed on Great Duck Island.  They have calculated the emotes have sufficient power to operate for the next six months, even though biologists will stop visiting the island.  The new data will provide insights into the climate activity through the fall and winter.  The performance so far is considered to be excellent.

17. 4/30/0316 Conclusion  Habitat monitoring represent an important class of sensor network applications.  The system which is designed is used at the College of the Atlantic to define the core application requirements.  As end users are ultimately interested in the sensor network system must deliver the data of interest in a confidence inspiring manner.
