Forwarding strategies for 6LoWPAN-fragmented IPv6 datagrams

Meer over het boek

This dissertation explores different implementation strategies for the fragment-forwarding aspect of the 6LoWPAN protocol for “low power and lossy networks” (LLNs). The performance in terms of latency and reliability for the LLN-typical collection traffic pattern is analyzed for several “direct” and “reassembling” strategies. A novel approach based on snooping and suspending transmissions is developed and it is shown that this approach improves the end-to-reliability significantly in most of the evaluated simulation and testbed scenarios.
