"Compression Format for IPv6 Datagrams in 6LoWPAN Networks", Jonathan Hui, Pascal Thubert, 30-Jun-09. ( bytes)

This document specifies an IPv6 header compression format for IPv6 packet delivery in 6LoWPAN networks. The compression format relies on shared context to allow compression of arbitrary prefixes. The information that is maintained in that shared context is out of scope. This document specifies compression of multicast addresses and a framework for compressing next headers. This framework specifies UDP compression and is prepared for additional transports.

"Design and Application Spaces for 6LoWPANs", Eunsook Kim, Dominik Kaspar, Nicolas Chevrollier, JP Vasseur, 9-Jul-09. ( bytes)

This document investigates potential application scenarios and use cases for low-power wireless personal area networks (LoWPANs). This document provides dimensions of design space for LoWPAN applications. A list of use cases and market domains that may benefit and motivate the work currently done in the 6LoWPAN WG is provided with the characterisitcis of each dimention. A complete list of practical use cases is not the goal of this document.

"6LoWPAN Neighbor Discovery", Zach Shelby, Pascal Thubert, Jonathan Hui, Samita Chakrabarti, Erik Nordmark, 12-Jul-09. ( bytes)

This document specifies Neighbor Discovery optimized for 6LoWPAN. The 6LoWPAN format allows IPv6 to be used over energy and bandwidth constrained wireless networks often making use of multihop topologies. However, the use of standard IPv6 Neighbor Discovery with 6LoWPAN has several problems. Standard Neighbor Discovery was not designed for non-transitive wireless links, and the standard IPv6 link concept and heavy use of multicast makes it inefficient. This document specifies a new ND mechanism allowing for the efficient detection of duplicate addresses over entire LoWPANs, which also optimizes other ND operations. In addition context dissemination, claim and defend address generation, and the support of Extended LoWPANs over Backbone Links are specified.

"Problem Statement and Requirements for 6LoWPAN Routing", Eunsook Kim, Dominik Kaspar, Carles Gomez, Carsten Bormann, 28-Jul-09. ( bytes)

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.
