Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing
The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demonstrated that structured signals can be acquired with just a small number of linear measurements, on the order of the signal complexity. In practice, this enables lower ...
Nested QoS: Providing flexible SLAs in shared storage systems
The increasing popularity of storage and server consolidation introduces new challenges for resource management, capacity provisioning, and application performance guaranteeing. In addition, the bursty nature of storage workloads results in a large gap between the peak and the average capacity required to meet response time bounds, leading to low ...
A minimum-cost-neighbor multicast routing protocol for mobile wireless ad hoc networks
MiCoN (Minimum-Cost Neighbor) is a new on-demand multicast routing protocol for mobile wireless ad hoc networks. Multicast routing in MiCoN is based on a new multi-route unicast routing protocol for maintaining routes between the network nodes and all group receivers. This routing is guaranteed to be loop-free even in the presence of dropped packets ...
Exploiting address space contiguity to accelerate TLB miss handling
The traditional CPU-bound applications of the past have been replaced by multiple concurrent data-driven applications that use lots of memory. These applications, including databases and virtualization, put high stress on the virtual memory system which can have up to a 50% performance overhead for some applications. Virtualization compounds this ...
The case for vehicular visible light communication (V2LC): Architecture, services and experiments
Visible Light Communications (VLC) is a fast-growing technology to provide data communication using low-cost and omni-present LEDs and photodiodes. In this thesis, we make the case for the use of vehicular VLC (V2LC) as follows. We describe an architecture for V2LC networks and introduce five network services that V2LC needs to provide for vehicular ...
A storage architecture for data-intensive computing
The assimilation of computing into our daily lives is enabling the generation of data at unprecedented rates. In 2008, IDC estimated that the "digital universe" contained 486 exabytes of data . The computing industry is being challenged to develop methods for the cost-effective processing of data at these large scales. The MapReduce programming ...
