Introduction to Wireless Sensor Network

Wireless sensor networks have opened the doors to many applications that require monitoring and control. Examples are wildlife habitat monitoring, environmental monitoring, structural monitoring, and target tracking. The underlying cost of developing a wireless sensor network is very cheap. with current technologies, an inexpensive wireless sensor network can be built with a low-cost processor, memory, and a radio antenna. A dense deployment of these wireless micro sensors, which consist of sensing, data processing, and communication power, can be used to collect and disseminate data. Compared to traditional sensor networks, wireless sensor networks allow immediate and fast access to collection a simpler task even for inaccessible areas. In essence, wireless sensor networks provide us with the ability to intelligently monitor and to understand the environment.
