5. Sensor Networks Preview A 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 locationswireless networkautonomoussensors temperaturesoundvibration pressure

7. They are used in commercial and industrial applications to monitor data that would be difficult or expensive to monitor using wired sensors. Application

8. Design Factors Make a statement with great looking graphics. PowerPoint makes it easy to produce visuals that used to require multiple applications to accomplish. Easily apply soft shadows, reflections, glows, bevels, 3D and more! Fault Tolerant Scalability Production Cost Tech Constraint Topology Stability Power Consumption

10. Routing in Sensor Networks Having no specific address, we can not use Internet Protocol. Special data flow model Redundant data Lack of power, energy, memory and processing, needs management.
