Optical wireless sensor network design for a conducting chamber

Now a day´s majority of the wireless sensor networks (WSNs) are based on Radio Frequency (RF) communication technology. But RF when used in an environment like that of metallic, conducting chamber exhibits large amount of interference due to multipath effects which degrades the performance of the sensor network. Infrared (IR) communication technology which is capable of overcoming the drawbacks exhibited by RF can be used in sensor networks. Suitable IR link can provide high efficiency and mobility. The paper presents design of one such sensor network based on IR communication technology to be deployed in a device known as Tokamak, used to conduct controlled nuclear fusion.
