The low-power Internet of Things (IoT) introduces lossy radio links with ultra-constrained frame sizes and high transmission cost for each byte. Information Centric Networking (ICN) is considered a promising communication technology in this regime, as it increases reliability by ubiquitous caching and eases transmission efforts by hop-wise forwarding. Common ICN layers such as NDN, however, were designed for fixed network infrastructure and require an adaptation layer to the constrained wireless—as the common Internet Protocol does.

In this paper, we design and evaluate such an ICN convergence layer for low power lossy links that (1) augments the NDN stateful forwarding plane with a highly efficient name eliding, (2) devises stateless compression schemes for standard NDN use cases with utile data encodings, (3) adapts NDN packets to the small MTU size of IEEE 802.15.4, and (4) generates compatibility with 6LoWPAN so that IPv6 and NDN can coexist on the same LoWPAN links. Our findings indicate that stateful compression can reduce the size of NDN data packets by more than 70 % in realistic examples, while packet fragmentation operates in a predictable way even for high fragment numbers. Our experiments show that for common use cases ICNLoWPAN saves 33 % of transmission resources over NDN, and about 20 % over 6LoWPAN.

为以信息为中心的物联网设计LoWPAN融合层

低功耗的物联网(IoT)引入了有损的无线电链路,其帧大小超受限,并且每个字节的传输成本较高。在这种情况下,以信息为中心的网络(ICN)被认为是一种有前途的通信技术,因为它通过无处不在的缓存提高了可靠性,并通过逐跳转发减轻了传输工作量。但是,像NDN这样的通用ICN层是为固定网络基础结构而设计的,并且像通用Internet协议那样,需要对受限无线进行适配的层。

在本文中,我们为低功耗损耗链路设计和评估了这样的ICN收敛层:(1)通过高效的名称消除来增强NDN有状态转发平面;(2)针对具有实用数据的标准NDN用例设计无状态压缩方案编码(3)使NDN数据包适应IEEE 802.15.4的小MTU大小,并且(4)生成与6LoWPAN的兼容性,以便IPv6和NDN可以共存于同一LoWPAN链路上。我们的发现表明,在实际示例中,有状态压缩可以将NDN数据包的大小减少70%以上,而即使对于高碎片数,数据包分段也可以以可预测的方式运行。我们的实验表明,对于常见用例,ICNLoWPAN通过NDN节省了33%的传输资源,而在6LoWPAN上节省了约20%的传输资源。
