Survey on Industrial Wireless Sensor Networks

Pavithra L, Angeline A

Wireless sensor network have benefits, due to their large benefits in terms of faster installation, lower cost, and flexible. Wireless sensor network operate in license-free Industrial Scientific and Medical(ISM) band hence share the spectrum with other technologies. In IWSN link failure occur because of multipath propogation from metallic surfaces, excessive electromagnetic noise and asymmetric capabilities. However, for industrial applications, new requirements such as reliable (in-time) delivery is a main constraint. A survey on industrial wireless sensor networks is presented.
