扩展6LoWPAN的一课--有损网络中的最小片段转发
A Lesson in Scaling 6LoWPAN -- Minimal Fragment Forwarding in Lossy Networks
摘要：
本文评估了物联网中碎片数据报的两种转发策略：逐跳重组和直接转发碎片的最小方法。最小片段转发受到6LoWPAN中后续片段处缺乏转发信息的挑战，因此需要节点处的额外数据。我们在广泛的实验中比较了这两种方法，评估了可靠性、端到端延迟和内存消耗。与以前的工作相比，由于我们的替代设置，我们得到了不同的结果和结论。我们的研究结果表明，直接片段转发应谨慎部署，因为链路层上更高的数据包传输速率可以显着降低其可靠性，这反过来又可以进一步减少端到端的延迟，因为高度增加链路层重传。
英文摘要：
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 is challenged by the lack of forwarding information at subsequent fragments in 6LoWPAN and thus requires additional data at nodes. We compared the two approaches in extensive experiments evaluating reliability, end-to-end latency, and memory consumption. In contrast to previous work and due to our alternate setup, we obtained different results and conclusions. Our findings indicate that direct fragment forwarding should be deployed only with care, since higher packet transmission rates on the link-layer can significantly reduce its reliability, which in turn can even further reduce end-to-end latency because of highly increased link-layer retransmissions.
