    Autonomic computing defines computational systems that are able to manage themselves with none or minimal human intervention. The concepts related to autonomic computing in computer networks leads to the development of a new concept: autonomic networks. This kind of network is able to perform self-management of its elements and data communication links. Smart environments represent the next evolut... View full abstract»

    Computing and communication are in flux today. On the communication side, historically there have been multiple, parallel networks servicing different types of traffic. Cost pressures are forcing convergence to a single IP-based network. Simultaneously the computing world has been steadily moving from monolithic applications to client/server systems, and from there to arbitrary distributed applica... View full abstract»

    The underground environment is a harsh and hazardous workspace for plant and personnel. It is damp, dusty and hot, there is a risk of roof and rock falling and the atmosphere can be potentially explosive. Recent incidents are a reminder of how crucial safety is in mining. The increasing miniaturization of RF devices and micro-electromechanical systems (MEMS) and the advances in wireless technologi... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (378 KB) | HTML iconHTML

    This paper presents an energy-efficient communication protocol which distributes a uniform energy load to the sensors in a wireless microsensor network. This protocol, called Distance-Based Segmentation (DBS), is a cluster-based protocol that divides the entire network into equal- area segments and applies different clustering policies to each segment to reduce total energy dissipation and hence p...

    This paper investigates implementation and design issues for a heterogeneous network for structural monitoring. The proposed application uses wireless sensors and the controller area network (CAN) to provide energy efficient monitoring. The contributions include: implementation of the PIC18f4680 platform in TinyOS, creating a message protocol over CAN, and developing a sensor board. View full abstract»

  • Topology Design of Optical Networks Based on Existing Power Grids

    Publication Year: 2007, Page(s):35 - 40
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (162 KB)

    In a power grid used to distribute electricity, optical fibers can be inserted inside overhead ground wires to form an optical network infrastructure for data communications. We consider the problem of topology design for such a network. To solve the problem, we modify existing methods for topology designs to take into account the topology limitation imposed by an existing power grid. For the desi... View full abstract»

    As terrestrial audio broadcasting is moving from the analog to the digital era, there is an interest from the broadcasting industry to re-examine the existing amplitude modulation (AM) and frequency modulation (FM) hardware. The objective is to identify potential problems which may arise when using digital signals with the existing systems. In particular, this paper analyzes the effects that an an... View full abstract»

    This paper introduces a computationally efficient parallel interference cancellation (PIC) receiver to reduce the complexity of the multiuser detectors for asynchronous code-division multiple-access (CDMA) systems. The complexity is reduced by employing the proposed energy activation functions (EAF). All the results are measures of the bit error rate (BER). Performance of the proposed algorithm in...

    Wireless sensor networks have mainly been designed for information-collecting purposes, such as habitat monitoring, product process tracing, battlefield surveillance, etc. In order to support efficient communications for such networks, many routing protocols have been proposed. However, protocol designs are out-pacing formal analysis. We propose an optimization model in this paper to bound the rou... View full abstract»
