             ICN Adaptation to LowPAN Networks (ICN LoWPAN)
                   draft-gundogan-icnrg-ccnlowpan-02

Abstract

   In this document, a convergence layer for CCNx and NDN over IEEE
   802.15.4 LoWPAN networks is defined.  A new frame format is specified
   to adapt CCNx and NDN packets to the small MTU size of IEEE 802.15.4.
   For that, syntactic and semantic changes to the TLV-based header
   formats are described.  To support compatibility with other LoWPAN
   technologies that may coexist on a wireless medium, the dispatching
   scheme provided by 6LoWPAN is extended to include new dispatch types
   for CCNx and NDN.  Additionally, the link fragmentation component of
   the 6LoWPAN dispatching framework is applied to ICN chunks.  Basic
   improvements in efficiency are advised by stateless and stateful
   compression schemes.
