The application-specific routing requirements for Urban Low Power and
Lossy Networks (U-LLNs) are presented in this document.  In the near
future, sensing and actuating nodes will be placed outdoors in urban
environments so as to improve the people's living conditions as well
as to monitor compliance with increasingly strict environmental laws.
These field nodes are expected to measure and report a wide gamut of
data, such as required in smart metering, waste disposal,
meteorological, pollution and allergy reporting applications.  The
majority of these nodes is expected to communicate wirelessly which -
given the limited radio range and the large number of nodes -
requires the use of suitable routing protocols.  The design of such
protocols will be mainly impacted by the limited resources of the
nodes (memory, processing power, battery, etc.) and the
particularities of the outdoor urban application scenarios.  As such,
for a wireless Routing Over Low power and Lossy networks (ROLL)
solution to be useful, the protocol(s) ought to be energy-efficient,
scalable, and autonomous.  This documents aims to specify a set of
requirements reflecting these and further U-LLNs tailored
characteristics.
