HTTP adaptive streaming (HAS) is quickly becoming a popular mechanism for delivering on-demand video content over the Internet. The chunked transmission and application-layer adaptation create a very different traffic pattern than traditional progressive video downloads where the entire video is downloaded with a single request. In this paper, we(More)
—The proliferation of pictures and videos in the In-ternet is imposing heavy demands on mobile data networks. Though emerging wireless technologies will provide more bandwidth, the increase in demand will easily consume the additional capacity. To alleviate this problem, we explore the possibility of serving user requests from other mobile devices located(More)
Content-Centric Networking (CCN) and Service-Centric Networking(SCN) are two novel paradigms that seek to change the way content and services are perceived. CCN is centered around content distribution, while SCN focuses on dynamic customization of in-network services. We present SoCCeR--Services over Content-Centric Routing. SoCCeR extends CCN with(More)
Mobile broadband demand keeps growing at an overwhelming pace. Though emerging wireless technologies will provide more bandwidth, the increase in demand may easily consume the extra bandwidth. To alleviate this problem, we propose using the content available on individual devices as caches. Particularly, when a user reaches areas with dense clusters of(More)
Our energy efficiency analysis of various content dissemination strategies reveals that a change in network architecture from host-oriented to content-centric networking (CCN) can open new possibilities for energy-efficient content dissemination. In this paper, we consider energy-efficient CCN architecture and validate its energy efficiency via trace-based(More)
The class of wireless and mobile networks features a dissimilar set of characteristics and constraints compared to traditional fixed networks. The various dimensions of these characteristics/constraints strongly influence the routing system, which is often regarded as the glue of a network. We introduce the concept of routing dependability describing the(More)
Swarm-based peer-to-peer streaming (SPS) mechanisms tend to generate a significant amount of costly inter-ISP traffic. Localization of overlay connectivity reduces inter-ISP traffic. However, it can adversely affect the delivered quality. In this paper, we systematically examine the performance of SPS for live video over localized overlays. We identify and(More)
