Sensor Networks Seminar Presentation

Wireless sensor networks (WSN), sometimes called wireless sensor and actuator networks (WSAN), are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. Sensor networks are dense wireless networks of small, low-cost sensors, which collect and disseminate environmental data.Its feature are local processing,wireless communication,complete system on chip, Integrated Low-power transducers. Nodes are in general deployed into an unplanned infrastructure (no priori knowledge). Problem of estimating the spatial co-ordinates is referred to as Localization (generally done by trilateral). Initial high-level nodes (beacons) broadcasts their address. (Proximity based Localization).
