A new design for Information Centric Networks

Abstract

Abstract-Information Centric Network (ICN) is a contentbased information dissemination approach that improves the content delivery and latency. We introduce a modified architecture for ICN which can reduce the traffic by combining multiple messages and facilitate the data distribution in the network. By observing the similarities between index coding and ICN architectures, we propose to combine these two techniques to arrive at a new architecture that enhances data delivery in networks beyond original ICN scheme. By taking advantage of some concepts such as linear network coding, caching and index coding, we demonstrate that we can reduce the traffic and increase the capacity of ICN architecture by combining (network encoding) multiple messages requested by different nodes and sending them in one transmission. We demonstrate that each node will be able to extract its desired message from the combined encoded messages. To achieve this goal, we first define a modified version of index coding in order to apply index coding for both wired and wireless networks. Further, we introduce a hybrid caching scheme that includes both central and distributed caching to support two different goals. Our hybrid caching approach is a combination of conventional caching in ICN that caches the content in various network locations in order to make the content readily available to nodes and a new distributed caching scheme across nodes in the network to improve the performance of the entire system. The purpose of the second caching scheme is to allow central cache system to combine multiple contents in order to serve several client nodes simultaneously with a single transmission of encoded messages. The focus of this paper is to describe the new ICN architecture and demonstrate the advantages of the new architecture.

Application of index coding in information-centric networks

“…In this paper, we assume the source node can access the receiver nodes through multihop communications. The new scheme, called Modified Index Coding (MIC) [9] technique, can be applied to different types of networks such as wireless multihop communication network, wired network or a hybrid network consisting of both wired and wireless channels. For example, in a corporate environment, we can have information transported in a wired medium while the last hop is a wireless access point with nodes connected to the infrastructure through a wireless modem.…”

Efficient Content Delivery and Caching Scheme Using Network Coding in CCN

“…Several solutions have been proposed. In some centralized schemes [6] [7], center routers are responsible for determining the optimal caching strategy and optimal content routing to provide independent blocks. In some distributed schemes [8] [9], the information about coded blocks having collected must be appended in the Interest packet to get independent block.…”

Caching with Unknown Popularity Profiles in Small Cell Networks

“…A recent development in this direction is to improve the accessibility of data content to users by storing the most popular data files in the local caches of small cell BSs, with the objective of reducing the peak traffic rates [5] - [8]. This is commonly referred to as "caching" and has attracted significant attention.…”
