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.

Terminology for Constrained-Node Networks

“…With respect to available power, [RFC6606] distinguishes "power-affluent" nodes (mains-powered or regularly recharged) from "power-constrained nodes" that draw their power from primary batteries or by using energy harvesting; more detailed power terminology is given in Section 4.…”

Implementation of secure 6LoWPAN communications for tactical wireless sensor networks

“…There have been studies that take into consideration an approach to implementing an efficient security mechanism for 6LoWPAN by either performing an analysis or survey [4,5]. Only a limited amount of research has been conducted implementing a proposed security framework over a multi-hop 6LoWPAN network [6].…”

Using IEEE 802.15.4e Time-Slotted Channel Hopping (TSCH) in the Internet of Things (IoT): Problem Statement

“…For these reasons, the 6LoWPAN WG has defined an effective adaptation layer [RFC6282]. Further issues encompass the autoconfiguration of IPv6 addresses [RFC2460] [RFC4862], the compliance with the recommendation on supporting link-layer subnet broadcast in shared networks [RFC3819], the reduction of routing and management overhead [RFC6606], the adoption of lightweight application protocols (or novel data encoding techniques), and the support for security mechanisms (confidentiality and integrity protection, device bootstrapping, key establishment, and management).…”
