Problem Statement and Requirements for IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Routing
6LoWPANs are formed by devices that are compatible with the IEEE
802.15.4 standard. However, neither the IEEE 802.15.4 standard nor the
6LoWPAN format specification define how mesh topologies could be
obtained and maintained. Thus, it should be considered how 6LoWPAN
formation and multi-hop routing could be supported. This document
provides the problem statement and design space for 6LoWPAN routing.
It defines the routing requirements for 6LoWPAN networks, considering
the low-power and other particular characteristics of the devices and
links. The purpose of this document is not to recommend specific
solutions, but to provide general, layer-agnostic guidelines about the
design of 6LoWPAN routing, which can lead to further analysis and
protocol design. This document is intended as input to groups working
on routing protocols relevant to 6LoWPAN, such as the IETF ROLL WG.
