Distributed sensor network

  1. 1. DISTRIBUTED SENSOR NETWORK
  2. 2. Sensor network: • It consists of multiple detection stations called sensor node • It is equipped with a transducer, microcomputer & transceiver and power source. • In sensor networks is basic on the defense application at the beginning, especially the Distributed Sensor Networks (DSN).
  3. 3. Types of sensor network: • There are many types of sensors. • They are used to measure and/or detect a huge variety of conditions Some are: • Common sensor • Bandwidth monitoring sensor • Web server (HTTP) sensor • SNMP sensor etc..
  4. 4. Distributed sensor network: The implementation of sensor network using distributed control architecture Reasons: • Sensor nodes are prone to failure • For better collection of data • To provide nodes with backup in case of failure of the central node
  5. 5. History: • In 1978,Defence Advanced Research Project Agency developed Distributed sensor network. Standards: There are a number of standardization bodies in the field of WSNs including WAVE2M and IEEE
  6. 6. Operating system: • Operating systems such as eCos or μC/OS used for sensor networks. • TinyOS is perhaps the first operating system for WSN • LiteOS and Contiki are the other new operating systems
  7. 7. Hardware: • WSN is to produce low cost and tiny sensor nodes. • Node contains: radio, battery, microcontroller, analog circuit, and sensor interface. Software: Algorithms and protocols need to address the following issues: • Lifetime maximization • Robustness and fault tolerance • Self-configuration
  8. 8. Working:
  9. 9. Layers used in data transmission:
  10. 10. Characteristics: • Power consumption using batteries or energy harvesting • Ability to cope with node failures • Mobility of nodes • Dynamic network topology • Scalability to large scale of deployment • Ability to withstand harsh environmental conditions • Ease of use
  11. 11. Routing technique:
  12. 12. Security Requirements: • Authentication • Secrecy • Countermeasures • Key Establishment Application: It consists of spatially distributed autonomous sensors to monitor physical or environmental conditions.
  13. 13. Military application: Services: • Battlefield surveillance • Targeting • Battle damage assessment • Nuclear, biological and chemical attack detection
  14. 14. Environmental Application: • habitat monitoring • agriculture research • fire detection • traffic control. • no interruption to the environment
  15. 15. Health Applications: • Widely used in health care area • Monitor patient physiological data. • To control the drug administration track.
  16. 16. Recent development of Home Applications: • Home application will step into our normal life in the future.
  17. 17. Conclusion: • The features of distributed sensor network is developing abruptly. • DSN has many advantages and is used in several fields. “It is going to make an evolution in the Technology world”.
