A Lesson in Scaling 6LoWPAN – Minimal Fragment Forwarding in Lossy Networks [article]

Martine S. Lenders, Thomas C. Schmidt, Matthias Wählisch
2019 arXiv   pre-print
Minimal fragment forwarding is challenged by the lack of forwarding information at subsequent fragments in 6LoWPAN and thus requires additional data at nodes.  ...  This paper evaluates two forwarding strategies for fragmented datagrams in the IoT: hop-wise reassembly and a minimal approach to directly forward fragments.  ...  Minimal Fragment Forwarding We extend 6LoWPAN in GNRC to support minimal fragment forwarding. One crucial implementation choice relates to the creation of the first fragment.  ...

Enhancing 6LoWPAN schemes to support priority driven routing

Ranabir Saha, Suman Sankar Bhunia, Nandini Mukherjee
2015 2015 IEEE International Conference on Advanced Networks and Telecommuncations Systems (ANTS)  
Internet of Things(IoT) has become an emerging area of research. 6LoWPAN is introduced to connect large number of things which are nothing but sensors of different capabilities.  ...  In 6LoWPAN, there are mainly two routing schemes, named as route-over (assembly mode) and mesh-under (direct mode), based on which layer is involved during routing decisions.  ...  The adaptation layer treats each incoming fragment indifferently. When a fragment is forwarded, mesh header is appended at the beginning of the 6LoWPAN header by the adaptation layer.  ...
