Wireless smart sensors networks overview

Wireless smart sensors are becoming very attractive devices in tele-monitoring, tracking moving objects, home automation, telemedicine and other industrial applications. They are small devices that gather information such as speed, humidity, pressure and temperature with high resolution and have very useful functions on the software level such as signal processing and data logging. They do measurements from different channels and adjust the data to support distributed processing and decision making. Wireless smart sensors provide clear advantages in power, size, cost, mobility and flexibility. The movement towards wireless smart sensor network technology has been established through applying different protocols such as IEEE 1451 standard. This paper describes the use of smart sensors informing an integrated wireless network. That includes the sensors architecture, their standards, network topologies, protocols, implementation issues, and information about the wireless sensor solutions.
