Performance implications for IoT over information centric networks

Abstract

Information centric networking (ICN) is a proposal for a future internetworking architecture that is more efficient and scalable. While several ICN architectures have been evaluated for networks carrying web and video traffic, the benefits and challenges it poses for Internet of Things (IoT) networks are relatively unexplored. In our work, we evaluate the performance implications for typical IoT network scenarios in the ICN paradigm. We study the behavior of innetwork caching, introduce a way to make caching more efficient for periodic sensor data, and evaluate the impact of presence and location of lossy wireless links in IoT networks. In this paper, we present and discuss the results of our evaluations on IoT networks performed through emulations using a specific ICN architecture, namely, content centric networking (CCN). For example, we show that the newly proposed UTS-LRU cache replacement strategy for improved caching performance of time series content streams reduces the number of messages transmitted by up to 16%. Our findings indicate that the performance of IoT networks using ICN are influenced by the content model and the nature of its links, and motivates further studies to understand the performance implications in more varied IoT scenarios.

Nesnelerin İnternetinde Kullanılan Kablosuz Algılayıcı Cihazlar için Bilgi Merkezli Ağ Mimarisinin Uygulanabilirliği Araştırması

“…Böylece veriyi yayınlayan ve tüketen kaynaklar birbirinden ayrılır. Veriyi talep eden düğümün hareketli olması veya verinin üretildiği düğümün periyodik-bazlı çalışması nedeniyle erişilememesi durumunda veri, başka bir yönlendirici düğümden elde edilebilmektedir (Rao, Schelén, &Lindgren, 2016). Bunun sonucunda birçok servis ve uygulama için veriye erişim imkânı artmaktadır (Lindgren, Abdesslem, Ahlgren, Schelén& Malik, 2016).…”

“…Kısıtlı kaynaklara sahip kablosuz cihazların, güvenli bir iletişim kanalı sağlamak için harcamakta olduğu enerji, şifreleme algoritmaları için harcayacağı enerjiden fazladır. Bu durumda, içeriğin kendisi ile entegre olan güvenlik yöntemleri kısıtlı cihazlar için verimli bir çözüm olma potansiyelini taşımaktadır (Rao et al, 2016). Bilgi merkezli ağ yaklaşımını, IoT uygulamaları ve geleceğin internet mimarisi için güçlü bir aday haline getiren mekanizmalardan biri de güvenliğin içeriğin kendisi ile sağlanmasıdır.…”

Lightweight Caching and Load Balancing for Efficient Content Delivery in Information-Centric IoT

“…However, the closer content requests are to the uniform distribution, the more beneficial cache diversity becomes, as a larger percentage of content objects are duplicated in the network. Since uniform request distributions are more common in IoT contexts [94,122], cache diversity will be emphasised in this thesis.…”

“…The Zipf distribution is commonly used in traditional ICN research because web content generally follows this pattern [55,127,144,167]. However, IoT content requests are very different from web content; they depend on the application but generally tend to approximate uniform distribution [94,122]. For this reason, this evaluation treats these two modes as the edge cases of request distribution, with real-world patterns likely to fall somewhere between the two.…”

“…After topology setup is complete, every node will request a piece of content with a random ID in {0, … , 49} from each of the prefixes in its FIB (with 50 producers, there are thus 2500 distinct objects that can be requested). Requested content IDs follow a uniformly random distribution to model the typical request distribution found in IoT applications [94,122]. Interest and Data packets are handled as specified by the NDN standard.…”
