低功耗互联网协议的设计考虑

Design Considerations for Low Power Internet Protocols

Hudson Ayers, Paul Crews, Hubert Teo, Conor McAvity, Amit Levy, Philip Levis

摘要:

在过去的10年中,低功耗无线网络已经通过6LoWPAN过渡到支持IPv6连接,6LoWPAN是一组标准,指定如何通过低功耗无线链路(如802.15.4)积极压缩IPv6数据包。我们发现,不同的低功耗IPv6堆栈无法使用6LoWPAN进行通信,因此IP,由于代码大小和能源效率之间的设计权衡。我们认为,应用传统的协议设计原则,低功耗网络是负责这些故障,部分原因是因为接收器必须适应广泛的带宽。基于这些发现,我们提出了三个低功耗网络上的互联网协议的设计原则。这些原则基于在代码大小和能量效率之间提供灵活的权衡的重要性。我们将这些原则应用于6LoWPAN,并表明协议的最终设计为开发人员提供了广泛的权衡点,同时允许实现不同的选择无缝通信。

英文摘要:

Over the past 10 years, low-power wireless networks have transitioned to supporting IPv6 connectivity through 6LoWPAN, a set of standards which specify how to aggressively compress IPv6 packets over low-power wireless links such as 802.15.4. We find that different low-power IPv6 stacks are unable to communicate using 6LoWPAN, and therefore IP, due to design tradeoffs between code size and energy efficiency. We argue that applying traditional protocol design principles to low-power networks is responsible for these failures, in part because receivers must accommodate a wide range of senders. Based on these findings, we propose three design principles for Internet protocols on low-power networks. These principles are based around the importance of providing flexible tradeoffs between code size and energy efficiency. We apply these principles to 6LoWPAN and show that the resulting design of the protocol provides developers a wide range of tradeoff points while allowing implementations with different choices to seamlessly communicate.
