Internet of Things Gets IPv6 Routing Protocol
Now that there are five times at many smart devices on the Internet as PCs, the Internet Engineering Task Force (IETF) has dedicated a new Low power and Lossy networks (LLN) routing protocol called Routing Protocol for LLNs (RPL). Hopefully, this new IPv6-based protocol should drive international standardization among vendors building networks of smart objects.
In the past, networks of sensors, actuators, even RFID tags, have been proprietary, leading to closed systems that limited innovation. Lead by Cisco, a working group with the IETF has produced the new standard which is expected to be fully adopted by the fall. Once implemented it should be useful in smart grids that control renewable energies and electric vehicles, home and building automation, healthcare, efficient water management, automotive and industrial automation.

A key milestone for the advancement of IP smart object networks is the development of their own routing protocol, that was approved this month by the IETF. Networks of IP-based smart objects can now be deployed to support a myriad of applications such as smart metering and smart grid networks, and to advance solutions for smart+connected communities. This is no longer a futuristic view thanks to the collaboration of a number of industrial partners and end users, including Cisco.
