Problem Statement and Requirements for
IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Routing
Abstract
IPv6 over Low-Power Wireless Personal Area Networks (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 defines 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 6LoWPANs,
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 that can lead to further analysis
and protocol design. This document is intended as input to groups
working on routing protocols relevant to 6LoWPANs, such as the IETF
ROLL WG.

1. Problem Statement
6LoWPANs are formed by devices that are compatible with the
IEEE 802.15.4 standard [IEEE802.15.4]. Most of the LoWPAN devices
are distinguished by their low bandwidth, short range, scarce memory
capacity, limited processing capability, and other attributes of
