Exploiting Efficient and Scalable Shuffle Transfers in Future Data Center Networks

Distributed computing systems like MapReduce in data centers transfer massive amount of data across successive processing stages. Such shuffle transfers contribute most of the network traffic and make the network bandwidth become a bottleneck. In many commonly used workloads, data flows in such a transfer are highly correlated and aggregated at the receiver side. To lower down […]

Video Transmission Over Lossy Wireless Networks: A Cross-Layer Perspective

Video content currently makes up nearly half of the “fixed” Internet traffic and more than a third of the mobile traffic in North America, with most other regions showing similar trends. As mobile data rates continue to increase and more people rely on 802.11 wireless for home and commercial Internet access, the amount of video transmitted over at least […]

Opportunistic Multihopping for Energy Efficiency: Opportunistic Multihop Cellular Networking for Energy-Efficient Provision of Mobile Delay-Tolerant Services

Cellular operators are facing considerable capacity and energy-efficiency challenges as cellular data traffic keeps rising. Several studies have shown that multihop cellular networks (MCNs) could help tackle these challenges through the integration of device-to-device (D2D) and cellular communications. This article demonstrates that significant energy- efficiency gains can be achieved when MCNs jointly exploit opportunistic networking and the […]

Analysis of ISP caching in information-centric networks

Information-centric networking (ICN) models have recently emerged as novel network architectures for dealing with current Internet usage, where most users are interested in retrieving content without regard to its physical location. In this paper, we consider a noncooperative game between an Internet Service Provider (ISP) and content provider (CP) in an ICN model where the […]

FluidNet: A Flexible Cloud-Based Radio Access Network for Small Cells

Cloud-based radio access networks (C-RAN) have been proposed as a cost-efficient way of deploying small cells. Unlike conventional RANs, a C-RAN decouples the baseband processing unit (BBU) from the remote radio head (RRH), allowing for centralized operation of BBUs and scalable deployment of light-weight RRHs as small cells. In this work, we argue that the […]
