  1. 1. POWER MANAGEMENT IN WIRELESS SENSOR NETWORK Presented By Vijeta-12/118“PowerManagement In Wireless Sensor Network ” JMIT , RADAUR
  2. 2. ABSTRACT Deployments in wireless sensor network for real life applications has rapidly increased. Still, Energy problem remains one of the major barrier somehow preventing the complete exploitation of this technology. Sensor nodes are typically powered by batteries with a limited Efficient energy management is thus a key requirement for a credible design of a wireless sensor. This paper presents an overview of the key technologies required for low-energy distributed micro sensors. “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 2
  3. 3. WIRELESS SENSOR NETWORK WSN is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 3
  4. 4.  Wireless – Communication via radio waves Autonomous – Independent; self-directed Ad hoc network – A network without a fixed, well- defined infrastructure Sensor node – Device that produces a measurable response to a change in physical condition “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 4
  5. 5. SENSOR NETWORKGatewaysensornode “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 5
  6. 6. SENSOR NODE A sensor node, also known as a ‘Mote‘ Node in a WSN that is capable of performing some processing, gathering sensory information and communication with gateway sensor node Different parts of sensor node require power for processing “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 6
  7. 7. Four subsystems: computing subsystem consisting of a microprocessor or micro controller, communication subsystem consisting of a short range radio for wireless communication, sensing subsystem that links the node to the physical world and consists of a group of sensors power supply subsystem, which houses the battery and the dc-dc converter, and powers the rest of the node. “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 7

  11. 11. Need for Power Management Sensor nodes - Battery Driven must have a lifetime on the order of months to years. Battery Replacement is not an option - thousands of physically embedded nodes. In some cases, Renew Energy from the Environment “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 11
  12. 12. POWER OPERATION IN NETWORK Power Used In Radio Communication Hardware Microcontroller Methods to design Energy-efficient networks Signal Processing in the Network System Partitioning Read, Write and Erase Energy Usage “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 12
  13. 13. POWER USED IN RADIO H/W The functionality of both transmitter and receiver are combined into a single device known as transceiver are used in sensor nodes. The operational states are transmit ,receive , idle and sleep Low Voltage Operation  1.8V minimum supply “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 13
  14. 14. MICROCONTROLLER :- Performs Tasks, Processes Data and Controls the functionality Flexibility ,power consumption is less, sleep state 1.8V power supply Active power 6mW Sleep power 3µw “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 14

  22. 22. CONCLUSION In human life a sensor network may be the powerful tool, because they can be deployed at the places where a man can not reach. Only by incorporating energy awareness into every stage of wireless sensor network design and operation, thus empowering the system with the ability to make dynamic tradeoffs between energy consumption, system performance, and operational fidelity. The network lifetime can be maximized “PowerManagement In Wireless Sensor Network ” JMIT , RADAUR 22
