Space efficiency and data reliability are two primary concerns for modern storage systems. Chunk-based deduplication, which breaks up data objects into single-instance chunks that can be shared across objects, is an effective method for saving storage ...

The prevalence of multicore architectures has made the performance analysis of multithreaded applications an intriguing area of inquiry. An understanding of locality effects and communication behavior can provide programmers with valuable information ...

We present LiveLab, a methodology to measure real-world smartphone usage and wireless networks with a reprogrammable indevice logger designed for long-term user studies. We discuss the challenges of privacy protection and power impact in LiveLab and ...

Laboratory-based mobile wireless testbeds such as MeshTest and the CMU Wireless Emulator are powerful platforms that allow users to perform controlled, repeatable, mobile wireless experiments in the lab. Unfortunately such systems can only accommodate ...

We propose to exploit online social networks in order to reveal user preferences such that goods and services might be targeted appropriately. We consider goods and services that are consumed periodically, and a user model where users could buy ...

Game-theoretic control is a promising new approach for distributed resource allocation. In this paper, we describe how game-theoretic control can be viewed as having an intrinsic layered architecture, which provides a modularization that simplifies the ...

This paper builds a complete modeling framework for understanding user churn and in-degree dynamics in unstructured P2P systems in which each user can be viewed as a stationary alternating renewal process. While the classical Poisson result on the ...

This paper explores the feasibility of and challenges in developing methods for black-box monitoring of the power usage of a virtual machine (VM) at run-time, on shared virtualized compute platforms, including those with complex memory hierarchies. We ...

Communications technology has great potential for helping other industries reduce their greenhouse gas emissions. Nevertheless, given the relentless growth of demand for communications services, telecommunications providers will need to transition to ...

Wireless local area networks have become an ubiquitous means for network access in both residential and commercial locations over the recent past. Given their widespread deployment, it is of importance to understand their environmental impact and this ...

To overcome the problem of unavailability of grid power in rural India, we explore the possibility of powering WSN Gateways using a bicycle dynamo. The "data mule" bicycle generates its own power to ensure a self sustainable data transfer scheme to ...

In order to provide high quality communications over a best-effort network, an alternative to complex QoS control procedures is represented by generously over-provisioning the network resources. This approach has guaranteed in the near past reasonably ...

Research on energy-efficiency of communication networks has already gained the attention of a broad research community. Specifically, we consider efforts towards improving environmental sustainability by making networks energyaware. An important step in ...
