A review of sensor networks: Technologies and applications

Sensing any change in the physical environment and delivering this real time information about the system to the remote station for analysis has created versatile applications. With the research and development in the science and technology new sophisticated wired and wireless technologies for sensing have been developed with time. This paper presents an overview of these technologies used for wired and wireless sensor networks. For wireless sensor network some features of zigbee, enOcean, wavenis, Z-wave, wifi and Bluetooth are discussed in this paper. Brief discussion of different applications of the sensor networks is also presented.
