Scientech-2311W V2.0 Understanding Wireless Sensor

Wireless Sensor Network (WSN) research has enabled large scale monitoring using small Sensors with radio links. The technological advance in wireless communications and microelectronics has enabled the development of small, low-cost Sensor Nodes. Wireless Sensor Networks are developed to organize and control these Sensor Nodes, which have sensing, data processing, communication and control capabilities. Information collected from these Sensor Nodes is routed to a sink Node via wireless communication approach. The research in the Wireless Sensor Network has focused primarily on the networks issues such as routing, data dissemination and aggregation of co-related data for downstream data delivery. The combination of small size, low cost and wireless networking functionality makes Wireless Sensor Network (WSN) technology exceptionally scalable.
