    A Comparison of TCP-Friendly Congestion Control Protocols

    Using the ns simulatior, the authors perform a detailed study of the fairness and the smoothness properties of SimdNR, an enhanced version of SIMD. The study includes TFRC and TCP congestion control protocols in both steady-state and highly dynamic network conditions through RED and DropTail routers. The results show that...

    Assessing the Impact of BitTorrent on DOCSIS Networks

    BitTorrent is a widely deployed peer-to-peer protocol that provides scalable le sharing capabilities. While Bit-Torrent applications contribute to the demand for high speed broadband access, they also contribute to the undesirable 80/20 effect wherein 80% of the bandwidth is consumed by 20% of the users. In this study the authors...

    Over-Height Vehicle Detection in Low Headroom Roads Using Digital Video Processing

    In this paper the authors present a new method for over-height vehicle detection in low headroom streets and highways using digital video processing. The accuracy and the lower price comparing to present detectors like laser radars and the capability of providing extra information like speed and height measurement make this...

    A Mobility Management Framework for Optimizing the Trajectory of a Mobile Base-Station

    The authors describe a software framework for prescribing the trajectory path of a mobile sink in a wireless sensor network under an extensible set of optimization criteria. The framework relies on an integrated mobility manager that continuously advises the sink using application-specific network statistics. They focus on a reference implementation...

    Using Reconfigurable Devices to Maximize Spectral Efficiency in Future Heterogeneous Wireless Systems

    As broadband data further blends with cellular voice, mobile devices will become the dominant portals to the connected world. However current design practices still involve building independent networks that each make their own resource decisions. In spite of the tremendous amount of related research in this area, there are still...

    Moving Beyond 4G Wireless Systems

    As broadband data further blends with cellular voice, mobile devices will become the dominant portals to the connected world. However current design practices still involve building independent networks that each makes their own resource decisions. To move beyond 4G, wireless networks will need to cooperate to provide better performing and...

    Adaptation of Modulation and Coding for OFDM Packet Transmission

    A novel protocol is proposed for adaptive modulation and coding for Orthogonal Frequency Division Multiplexing (OFDM) in packet radio networks. Previous protocols in the literature rely on channel measurements or parameter estimates to provide channel state information, which is then processed to determine the appropriate transmission parameters. The authors' proposed...

    ISO 14000 Standards: Voluntary Environmental Governance As A Trade Facilitation Strategy?

    The continued increase in social and environmental consciousness, coupled with an increasingly globalized marketplace, has fostered an increasingly important role for independent environmental standards. Among the most widely recognized and internationally accepted of such programs is the ISO 14000 Environmental Management Standard (EMS). The intent of ISO 14000 is not...

    Estimation Of A Backward-bending Investment Demand Function For Agribusiness Firms

    The authors investigate irreversible investment behavior under uncertainty of payoffs using U.S. firm-level panel data. They estimate the relationship between the firm's investment to capital ratio and the interest rate, while controlling for investment opportunities, real option values, uncertainty and profitability. The results indicate the investment demand curve is a...

    Applying the Lessons of RESOLVE to a Functional Programming Language

    One fundamental, yet insufficiently-investigated question in the study of software verification is: "How does the nature of a programming language impact its prospects for verifiability?" In some situations the answer is clear, e.g., a language with reference semantics is harder to reason about than one with value semantics, but in...

    Towards a Unified Wireless Network Involving Reconfigurable Devices

    Rapid advances in wireless and mobile device technology are transforming society. As broadband data further blends with cellular voice, mobile devices will become the dominant portals to the connected world. Concurrently, there will be an explosion of domain specific applications that require wireless connectivity. Domains include intelligent transportation systems, smart...

    Virtual Organization Clusters: Self-Provisioned Clouds on the Grid

    Virtual Organization Clusters (VOCs) provide a novel architecture for overlaying dedicated cluster systems on existing grid infrastructures. VOCs provide customized, homogeneous execution environments on a per-Virtual Organization basis, without the cost of physical cluster construction or the overhead of per-job containers. Administrative access and overlay network capabilities are granted to...

    Scavenger Hunt: An Embedded Wireless System Approach

    Recent statistics have shown the decline in the number of students choosing computer science as an undergraduate degree in the United States of America. This problem is pressing as the supply of qualified computer scientists is decreasing while demand for computer scientists in industry and academia is increasing. Accordingly, many...

    Cable Modem Buffer Management in DOCSIS Networks

    A critical component of subscriber management in a DOCSIS-based cable access network is the buffer management strategy that is in operation at the upstream service flow queue located in the cable modem. The strategy must contend with conflicting goals: large buffers might be required to ensure TCP flows can utilize...

    Self-Provisioned Hybrid Clouds

    Virtual Organizations are dynamic entities that consist of individuals and/or institutions established around a set of resource-sharing rules and conditions. The VO may require the use of on-site (local) and off-site (public) compute resources that can be leased or autonomically provisioned, based on workload and site policies. Virtual Organization Clusters...

    A Note on the Data-Driven Capacity of P2P Networks

    The authors consider two capacity problems in P2P networks. In the first one, the nodes have an infinite amount of data to send and the goal is to optimally allocate their uplink bandwidths such that the demands of every peer in terms of receiving data rate are met. They solve...

    The Occupations And Human Capital Of U.S. Immigrants

    This paper estimates the multi-dimensional human capital endowments of immigrants by characterizing their occupational decisions. This approach allows for estimation of physical skill and cognitive ability endowments, which are difficult to measure directly. Estimation implies that immigrants as a whole are abundant in cognitive ability and scarce in experience/training and...

    Cash Flow And Product Market Competition: An Empirical Analysis

    Using a tax-induced negative shock to expected cash flows in the tobacco industry as a natural experiment, the author finds significant positive returns to rivals who compete with non-tobacco segments in tobacco firms and a significant change in output behavior of those non-tobacco segments after the shock. This suggests that...
