wireless sensor network my seminar ppt

  1. 1.  Large number of heterogeneous Sensor node devices spread over a large field. Wireless sensing + Data Networking.Smart Sensor Nodes: Low power devices Consists of- one or more sensors, a processor, memory, a power supply, a radio and an actuator. Eisha Madhwal 5/30/2012 2
  2. 2. 1. Unstructured WSN 2. Structured WSN Dense collection of  Few and scarcely nodes distributed nodes Ad-hoc deployment  Pre-planned deployment Difficulty in network  Lower network maintenance maintenance Eisha Madhwal 5/30/2012 3
