Routing Requirements for Urban Low-Power and Lossy Networks
2009
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.
