    A Measure of Dependence for Cryptographic Primitives Relative to Ideal Functions

    In this paper, the authors present a modification of a well-established measure of dependence appropriate for the analysis of stopping times for adversarial processes on cryptographic primitives. They apply this measure to construct generic criteria for the ideal behavior of fixed functions in both the random oracle and ideal permutation...

    Distributed Algorithms for Bottleneck Identification and Segmentation in 3D Wireless Sensor Networks

    Segmentation decomposes a network with complex and irregular shape into a set of subnetworks, each under a simple boundary condition without bottlenecks. It has a wide spectrum of applications in routing, coverage, localization, backbone construction and maintenance, and in-network data centric storage and retrieval. To the authors' best knowledge, this...

    Mobile Node Rostering in Intermittently Connected Passive RFID Networks

    This paper focuses on the problem of rostering in intermittently connected passive RFID networks. It aims to report a list of tagged mobile nodes that appear in given interested area(s) and time interval(s). Such rostering faces several unique challenges. First, the network consists of two dramatically different types of nodes:...

    A Distributed Triangulation Algorithm for Wireless Sensor Networks on 2D and 3D Surface

    Triangulation serves as the basis for many geometry based algorithms in wireless sensor networks. In this paper, the authors propose a distributed algorithm that produces a triangulation for an arbitrary sensor network, with no constraints on communication model or granularity of the triangulation. They prove its correctness in 2D, and...

    Cross-Layer Hop-by-hop Congestion Control in Mobile Ad Hoc Networks

    The poor performance of TCP in wireless networks is further diminished in IEEE 802.11-based ad hoc networks due to the unnecessary actions of on-demand routing protocols when interference-induced packet drops occur at the Medium Access Control (MAC) layer. In this paper, the authors present a cross-layer hop-by-hop congestion control scheme...

    Evaluating Mobile Ad Hoc Networks: A Performance Index and Statistical Model

    This paper is concerned with defining a performance index that can be used as an objective measure in the evaluation and comparison of ad hoc networking protocols. Specifically, the authors introduce a performance index that aggregates performance results from multiple response metrics into a single scalar value that quantifies overall...

    Continuous Auditing in ERP System Environments: The Current State and Future Directions

    Recent research has focused heavily on the practicality and feasibility of alternative architectures for supporting continuous auditing. In this paper, the authors explore the alternative architectures for continuous auditing that have been proposed in both the research and practice environments. They blend a focus on the practical realities of the...

    Cloud Computing for Small Nonprofits: Affordable, Leapfrogging Technology

    Cloud computing may become the mechanism for organizations that are struggling to provide adequate IT capabilities to leapfrog to more effective and affordable IT infrastructures and software solutions. For small nonprofit organizations, critical information systems, such as those that monitor delivery of programs and services, may be migrated from spreadsheets...

    An Opportunistic Virtual MISO (OVM) Protocol for Multi-Hop Wireless Networks

    By allowing neighboring nodes to effectively share their available resources, cooperative diversity-based protocols have shown improvements over the traditional routing and Medium Access Control (MAC) protocols. In this paper, the authors observe that while cooperative diversity-based protocols yield performance improvements in the presence of low-quality links, their performance improvements in...

    Design and Implementation of CLASS: A Cross-Layer Association Scheme for Wireless Mesh Networks

    In the IEEE 802.11 standard, a Mobile Station (MS) associates to an Access Point (AP) which has the best Received Signal Strength Indication (RSSI) value during its scanning. However, in 802.11-based wireless mesh networks, the conditions of the access link (e.g., traffic load of associated stations, and the frame error...

    AES and DES Encryption with GPU

    The GPU can be used as a cost efficient hardware performance enhancer for both the AES and DES algorithms. If the amount of data is large enough both algorithms can greatly reduce the encryption time required by both algorithms. Placement of the key scheduling algorithm, however, is not guaranteed to...

    Hierarchical Clustering With CUDA/GPU

    Graphics Processing Units (GPUs) on commodity video cards have evolved into powerful computational devices tailored towards the needs of the 3-D gaming industry for high-performance, real-time graphics engines. In the past, software development on GPUs has been geared exclusively towards graphics through the use of languages such as OpenGL shading...

    Investigating Deployment Strategies for Multi-Radio Multi-Channel Residential Wireless Mesh Networks

    Multi-radio multi-channel Wireless Mesh Networks (WMNs) are being increasingly deployed for broadband provision in enterprise, community, metropolitan and rural areas, due to their lower cost and faster deployment compared to the traditional wired broadband networks. In comparison with the former single-radio WMNs, multi-radio multi-channel WMNs can provide higher capacity and...

    Common (Stock) Sense About Risk-Shifting And Bank Bailouts

    If a bank faces potential insolvency, it will be tempted to reject good loans and accept bad loans to shift risk onto its creditors. The authors analyze effectiveness of buying up toxic mortgages in troubled banks, buying preferred stock, and buying common stock. If bailouts for banks that are deemed...
