Empirically modeling how a multicore software ICN router and an ICN network consume power

Abstract

ICN (Information Centric Networking) has received much attention due to its built-in functionalities such as caching and mobility-support. One of the important research challenges is to reduce the power consumed by ICN networks because ICN's packet forwarding and packet-level caching are power-hungry. As the first step to achieve power-efficient ICN networks, this paper develops a power consumption model of a multicore software ICN router while taking into account the power consumed by power-hungry computation. This paper makes the following three contributions: First, the model is one of the first realistic models which consider ICN packet forwarding and packet-level caching. Second, the model is represented as a concise set of equations with just a few parameters. Third, we apply the model to estimate power consumed by simple networks.

Efficient content delivery in mobile ad-hoc networks using CCN

“…The expected energy consumption for α-hop content delivery with i times interest issuing, E(R, α), can be induced by (28) and (29).…”

“…The energy consumption is estimated by (3) for AODV. In case of LFBL and the proposed scheme, additional energies for caching and ICN packet processing (FIB/PIT lookup) are considered based on [28]. Every simulation is repeated 10 times with different random seeds and the average values are plotted with min/max bounds in each graph.…”

“…Thus an ICN router will not necessarily reduce energy consumption even if it can reduce the number of hops. To clarify this trade-off, we modeled the energy consumption of an ICN router [23]. This subsection shows a primary analysis using the model.…”

On Energy Reduction and Green Networking Enhancement Due to In-Network Caching

“…On the one hand in-network caching in information centric networking (ICN) is considered as one of promising approaches to reducing energy consumption of an entire network [1], [2], but on the other hand it is considered as a somewhat energy consuming technique [3], [4].…”

“…In [4], the authors reveal that in-network caching has a negative effect on energy consumption. We simply refer to in-network caching as caching, hereafter.…”
