Wireless Sensor Network

• What is a wireless sensor network?
• A computer network consisting of
• spatially distributed devices.
• What do devices contain?
• Memory, radio, processor, battery

Wireless Sensor Network

• Goal To collect data from remote sites for
  USEFUL decision making
• Main features of WSNs
• Intelligent control e.g. automatic
• data collection and processing
• Self configuration
