This document summarizes a proposed landslide monitoring system using a wireless sensor network. It discusses how sensor nodes would collect data on factors like slope movement and moisture levels, forward it to a gateway, and ultimately to a field management center. An example is given of how such a system could monitor railway lines in mountainous areas. The current disadvantages of high cost, limited range, and slow data transmission are identified. An improved design is proposed using Zigbee modules for their low cost, high data rates, and ability to communicate over a broader range. The conclusion states the goal is to optimize the system to reduce costs and energy use while extending the lifetime of the wireless sensor network.

3. Group Picture

4. Introduction
• A collapse of a mass of earth or rock from a
mountain or cliff.
• They can be triggered by rain , floods , and
earthquakes as well as man made factors
such as slope grading or mining
• Landslides have the potential to happen
anywhere a steep slope is present

5. Damages
• Destroys the slope/hill
• Eliminates all vegetation
• Buries houses and sometimes entire villages
• Weakens the slope and makes it more
susceptible to further landslide
Some preventing methods :
• WSN ( wireless sensor networking)
• Rechargeable battery sensor
• Remote control sensor

6. Landslides prediction by WSN
• Data retrieved using spatially
distributed WSN.
• Wireless sensor nodes forward data on
to a gateway.
• Gateway sends data via a directional
wi-fi link to a field data management
center (FMC).
• Finally collected at a data management
center through a satellite link 252km
away from the deployment field.

7. Wireless sensor networks, individual sensors,
communication

8. Mechanism of WSN in landslide prediction

9. An example of using WSN in railway mountain
areas

10. Disadvantages
• Monitoring system tend to thin out with the times due to the loss of hardware
components.
• Maximum range is about 50m.
• Expensive
• Takes time to give data.

11. Introducing Zigbee
• The main hardware module used in this project
• Two zigbee modules
• Can communicate at high data rates
• Using peer to peer communication
• There is no data loss

12. Development of landslide detection
• Target is to reduce not only cost but also time
• transmitter side zigbee
• receiver side zigbee
• Sensor Nodes send data directly to receiver zigbee
• Power supply is used
• No human involvement neededPresent system Proposed system
This system has less
range, such as 50m.
By attaching a wireless
antenna, this will have
a broad range.
The system is
expensive.
Zigbee module and
power supply is cheap.
Takes time to
calculate data
transmission and give
decision.
Calculates everything
in a very short period
of time.

13. Conclusion
• This development provides the experience of design, development, and
deployment of a wireless sensor network for landslide detection. We plan to
determine the optimal number of geophysical sensors and wireless sensor
nodes with the hope of reducing the cost and energy consumption and thus
increasing the lifetime of the network.
