routing over low power lossy networks (IETF, RPL) (RoLL)

Routing over Low Power and Lossy Networks (RoLL) is a working group of the Internet Engineering Task Force ( IETF) that addresses routing requirements over Low Power and Lossy Networks( LLN) and has developed the Routing Protocol for Low Power and Lossy Networks( RPL) for this purpose.

The RPL protocol forms robust topologies over lossy links with minimal link state requirements. It is particularly suitable for use in sensor networks whose requirements are not sufficiently met by well-known routing protocols such as Open Shortest Path First( OSPF), the IS-IS protocol, or Optimized Link-State Routing( OLSR). The RoLL protocol is described in RFC 6550.
