Wireless Sensor Networks: Applications and Impact

Nowadays, Wireless Sensor Networks (WSNs) are increasingly becoming popular from all over the world. The applicability of WSN is increasing day-by-day in numerous arenas. Sensed data is being collected, stored and shared using WSNs. WSNs are applicable in various fields like home control, building automation, industrial automation, medical applications, sensor and robots, reconfigurable sensor networks, highway monitoring, military applications, civil and environmental engineering applications, wildfire instrumentation, habitat monitoring and nanoscopic sensor. WSN architecture is basically divided into two types, one is layered and the other is clustered architecture where the functionality of sensor nodes to other nodes is described in detail. In this paper, we emphasize on exploring the applications of WSN in different arenas. In wireless communication, WSN has chartered a new course.
