Caching on the move: Towards D2D-based information centric networking for mobile content distribution

Abstract

With the advent of device-to-device (D2D) communications, user equipment (UE) such as smart phones will become an integral part of the (mobile) network for content distribution operations. In this context, we introduce a novel Information centric networking (ICN) framework for mobile content caching and distribution based on direct D2D communications in cellular network environments. Specifically, small pieces of mobile content can be cached at incentivised mobile UEs known as helpers, and the ICN-aware cellular network edge (e.g. base stations) are able to resolve content requests from local mobile clients to the helpers in their D2D proximity. With simple POI (point of interests) based selection of helpers as well as content caching/eviction control at the base station side, a significant proportion of mobile content requests can be locally resolved to helpers in proximity of clients, thus achieving very effective content traffic offloading away from the cellular network infrastructure.

Investigating Network Services Abstraction in 5G Enabled Device-to-Device (D2D) Communications

“…2) Infrastructure Service Level: This level consists of network services for D2D communication such as ProSe, service sharing, service discovery, resource allocation, content discovery and delivery to the user, locating and delivering services to UEs [19] [20] [21].…”

“…Moreover, user's relationship is used to create cost function as well social ties and physical distance. The authors in [19] discussed content distribution in D2D communication network. A novel information centric networking framework using mobile content caching and distribution for direct D2D communication was proposed.…”

Cluster head selection method for content‐centric mobile social network in 5G

“…Since the cache size of a CH is limited, cache replacement/eviction policy plays a great role to increase hit ratio. In general, BS instead of serving separately each user's requesting (a popular video, or popular news), pre‐pushed a few copies of the content in some CHs and they can further forward it to any other user that makes a request for it [12, 13]. The main duties of the BS are to select CHs for a community, to pre‐push the popular contents toward the CHs to cache, and to deliver requested data directly to the requester if not hit locally.…”

QoE-Driven DASH Video Caching and Adaptation at 5G Mobile Edge

“…Traditionally, researches on in-network caching have been mainly conducted in the context of fixed ISP networks. However, there have also been recent proposals that are made towards caching at the edge of mobile cellular networks [12] or at the device side [3].…”
