Title : RPL: Routing Protocol for Low Power and Lossy Networks
Author(s) : T. Winter, et al.

Low Power and Lossy Networks (LLNs) are made largely of constrained
nodes (with limited processing power, memory, and sometimes energy
when they are battery operated). These routers are interconnected by
lossy links, most of the time supporting only low data rates, that
are usually fairly unstable with relatively low packet delivery
rates. Another characteristic of such networks is that the traffic
patterns are not simply unicast, but in many cases point-to-
multipoint or multipoint-to-point. Furthermore such networks may
potentially comprise a large number of nodes, up to several dozens or
hundreds or more nodes in the network. These characteristics offer
unique challenges to a routing solution: the IETF ROLL Working Group
has defined application-specific routing requirements for a Low Power
and Lossy Network (LLN) routing protocol. This document specifies
the Routing Protocol for Low Power and Lossy Networks (RPL).
