Hi Karl, Our group, Wireless Network Group of the Technical University of Catalonia, is currently working on a 6lowpan scheme over IEEE 802.15.4 networks, with interest on the field of sensor networks. Our current work is based on a minor implementation of IETF 6lowpan WG directives, an mainly hold on a base of contributions from TinyOS community.
The current implementation runs over TinyOS and its been tested over commercial TelosB research platform. The main IP stack is based on the adaptation made by HP Labs of the reduced uIP stack of SICS, but updated to work on an Adhoc environment based on FFD (compared to HPLabs which based its facilities on a FFD acting as an access point for a network of RFD) and to fulfill the points stated on the different drafts released. Currently our implementation have: - reduced IPv4 stack (mainly based on uIP of SICS) - 6lowpan header (without header compression neither fragmented paquets) - 6lowpan routing with DYMO and LOAD implementation - Nowadays we are using short addresses inside the PAN. We are working on: - Add packet fragmentation and header compression - adapting reduced IP stack to IPv6. - Usage of IPv6 link addresses - Add an autoconfiguration short address scheme based on 6lowpan directives We havent published yet any results neither code as opensource. Currently we are debugging but we plan to release the code soon. If you are interested on it, we can provide it to you.
