  1. IETF 6LoWPAN WG 65th, Dallas, Tx 6LoWPAN Ad Hoc On-Demand Distance Vector Routing (LOAD) Ki-Hyung Kim, S. Daniel Park, G. Montenegro, S. Yoo, and N. Kushalnagar draft-daniel-6lowpan-load-adhoc-routing-02.txt

  2. Change Log • Define the route cost by LQI and weak links • Hop counts while avoiding weak links • Several comments • Default value of weak LQI • The necessity of the sequence number to prevent routing loop • Interaction between QoS metric and distance vector routing • Lifetime definition • Link monitoring (route timeout by timers?) • Weak link indicator by LQI • Unidirectional links • RERR for low battery and “route cost not supported” should be avoided

  3. Prototype Implementation • http://www.6lowpan.org • Test bed Implementation • Segmentation and Reassembly • Header compression (Format document) • Gateway between 6lowpan and IPv6 networks • LOAD • Hi-Low

  4. Overall Architecture of the 6lowpan Testbed

  5. Protocol stack of 6lowpan router

  6. Portal for 6lowpan networks

  7. Socket-based Communication Socket-based client in IPv6 networks

  8. Summary • Feedback is welcome
