    The Impact of Multi-Outage Episodes on Large-Scale Wireless Voice Networks

    Large wireless network infrastructures experience concurrent or overlapping service outages due to equipment and link failures. The frequency, duration, and impact of such episodes are of interest to users and network operators alike. Here, a research project which investigates through simulation the characteristics of concurrent network outages in large wireless...

    Evaluation and Performance Analysis of Energy Efficient Wireless NoC Architecture

    As Network-on-Chip (NoC) architectures become more relevant with an increasing number of cores on a chip, research into emerging technologies and devices to replace power hungry global metallic interconnects has become critical. In this paper, the authors propose a practical wireless architecture called GLOW, a global wireless interconnect for NoCs....

    Modeling Urban Peer-To-Peer Channel Multipath Characteristics for the 700 MHz and 4.9 GHz Public Safety Bands

    The authors report on models developed for peer-to-peer (ground-based) wireless channels for an urban environment in the 700 MHz and 4.9 GHz bands, both allocated for public safety and "Emergency responder" applications. Results are based upon measurements taken in downtown Denver, CO for link distances up to approximately 100 m....

    Energy Efficient Modulation for a Wireless Network-on-Chip Architecture

    As both power consumption and leakage currents will limit the scalability of future massively integrated computational systems, research into emerging technologies and devices to replace traditional metallic interconnects has become critical. In this paper, the authors propose an initial implementation for a hybrid Wireless Network-on-Chip (WiNoC) interconnect architecture, named iWISE,...

    Energy-Efficient and Fault-Tolerant Unified Buffer and Bufferless Crossbar Architecture for NoCs

    Network-on-Chip (NoC) architecture is considered to be an attractive solution to overcome the combined problems of limited bandwidth and scalability in multicores. Input buffering at the router allows the network to sustain the accepted throughput without performance degradation. However, the input buffers consume a substantial portion of the total power...

    iWISE: Inter-Router Wireless Scalable Express Channels for Network-on-Chips (NoCs) Architecture

    Network-on-Chips (NoCs) paradigm is fast becoming a defacto standard for designing communication infrastructure for multicores with the dual goals of reducing power consumption while improving performance. However, research has shown that power consumption and wiring complexity will be two of the major constraints that will hinder the growth of future...

    Performance of Common Data Communications Protocols Over Long Delay Links: An Experimental Examination

    This paper presents a number of experimental findings regarding the efficiency of terrestrial protocols when they are used over a satellite link at data rates of about 1.5 Mbits/sec. In particular, the authors present measurements on TCP/IP and a theoretical model which explains the observed performance and points towards possible...

    Scalable Nanophotonic Interconnect for Cache Coherent Multicores

    While snoop-based cache-coherence protocols provide fast cache-to-cache transfer, scaling the cache coherence protocols has been difficult due to the overhead of broadcasting requests using electrical networks. Therefore, as multicores increase exponentially with each technology generation, it is necessary to re-think the design of power and area-efficient interconnects to enable fast...

    Shareholder Protection, Ownership Concentration And FDI

    Host country's weaker legal shareholder protection may make it costlier for parent shareholders to monitor the foreign subsidiary and hold managers accountable in case of misconduct. This prospect may motivate the managers to invest in such foreign environments. However, the agency costs associated with such investments can increase as well....

    Disaster Recovery Applications for Satellite Communications Systems

    The authors report on a series of experiments conducted jointly by Ohio University and The Huntington National Bank. The aim was to determine if ACTS-based data communications services can serve as redundant facilities in an otherwise terrestrial network. The authors examined both technical compatibility and network management issues. In addition,...

    Algorithms for a Network Design Problem With Crossing Supermodular Demands

    This paper presents algorithms for a class of directed network design problems. The network design problem is to find a minimum cost sub graph such that for each vertex set S there are at least f(S) arcs leaving the set S. In the last 10 years general techniques have been...

    E-Diophantine: An Admission Control Algorithm for WiMAX Networks

    Admission control algorithms must ensure that, when a new QoS resource reservation is accepted, reservations already present in the system continue having their QoS guarantees honored. In this paper, the authors consider different approaches to compute the aggregated allocated capacity in WiMAX networks and, based on their limitations, propose the...

    Virtualization as a Green IT Technology at Ohio University

    Two Green IT initiatives that have proportionally large potentials to save energy and money are server virtualization and desktop virtualization. Server virtualization electricity savings can be estimated using a speculative methodology with server hardware specifications as input and the use of the datacenter metric of Power user Efficiency (PuE). VMware's...

    Low-Power Low-Area Network-on-Chip Architecture Using Adaptive Electronic Link Buffers

    In the deep sub-micron regime, the performance of Network-on-Chip (NoC) architectures is bound by the limited power and area budget. Proposed is a low-power low-area NoC architecture using a novel power-efficient control circuit that enables repeaters along the inter-router links to function as adaptive link buffers, thereby reducing the number...
