EnOcean

EnOcean is a radio protocol that belongs to the WHAN group. The main caracteristic of EnOcean is that it doesn't need any energy supply. Indeed, it combines micro-energy converters with ultra-low power electronics and reliable wireless communications.. It’s powered by environment: electromagnetic energy, thermic energy, vibrations, and light. Thus, it has also a weak environment impact. To limit the consumption, EnOcean uses less protocol bytes (7 bytes instead of 40 for IPv6), it is then more efficient for small packets of data. As EnOcean technology does not require any battery, it does not need any reconstruction and it need very rare maintenance. It is then more easy and cost less in general after the setup. We can imagine to put sensors that uses EnOcean in a environnement that is hardly reachable, without having problem afterward, which is not the case for other communication technology.
