    Publication Year: 2004, Page(s):4 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (309 KB) | HTML iconHTML

    The PIES algorithm presents a new energy saving technique that helps conserve energy that is consumed by the wireless interfaces of ad hoc network nodes. PIES is not a routing algorithm, rather it is an algorithm that works in conjunction with existing routing protocols to help those protocols make decisions regarding energy conservation. PIES functionality conforms to the principle of energy fair... View full abstract»

  • Accurate multihop clock synchronization in mobile ad hoc networks

    Publication Year: 2004, Page(s):13 - 20
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (342 KB) | HTML iconHTML

    Clock synchronization is a critical service for many network applications. In mobile ad hoc networks, traditional clock synchronization algorithms like NTP are not applicable due to the mobility of nodes. Reference broadcast synchronization (RBS) takes advantage of the broadcast communication property in wireless networks and can achieve high accuracy in one broadcast domain, but RBS is not scalab...

  • Controllable fair QoS-based MAC protocols for ad hoc wireless networks

    Publication Year: 2004, Page(s):21 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (307 KB) | HTML iconHTML

    In this paper, we propose two techniques supporting differentiated service for different priority packets, Differentiated Fair ID Countdown (DFIC) and Controllable Fair ID Countdown (CFIC). DFIC supports absolute service differentiation among classes through the use of an explicit priority segment, while CFIC achieves prioritized access through assigning different waiting times for nodes to access...

    This paper introduces a novel Quality of Service Adaptive Call Admission Control (QoS-AdCAC) framework for next generation broadband wireless cellular networks supporting wireless multimedia services with different classes of traffic and diverse bandwidth requirements. In this work, each base station locally, independently of other base stations in the network, differentiates between new and hando... View full abstract»

  • A hierarchical micro-mobility management model with QoS capability

    Publication Year: 2004, Page(s):38 - 45

    The design of micro-mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time multimedia applications. We present a new hierarchical model for micro-mobility management with quality of service (QoS) capability for the wireless access network. The scheme includes an anchor ... View full abstract»

  • A pull-based broadcast algorithm that considers timing constraints

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (285 KB) | HTML iconHTML

    There are many situations in which we need to incorporate real-time constraints in broadcasting systems for mobile environments. In this paper, we study broadcast scheduling strategies for pull-based broadcast with timing constraints in the form of deadlines. Unlike previously proposed scheduling algorithms for broadcast systems which aim to minimize the mean access time, our goal is to identify s... View full abstract»

    In recent years the idea of access network has changed radically, and the diffusion of wireless technologies, and especially IEEE 802.11 compliant devices, has made wireless connections increasing popular. Despite the great success of the IEEE 802.11 standard, several problems concerning security, power consumption and quality of service of wireless LANs remain partially unsolved. The QoS issue is...

  • Coverage issue in sensor networks with adjustable ranges

    Publication Year: 2004, Page(s):61 - 68
    Cited by:  Papers (14)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (374 KB) | HTML iconHTML

    In this paper, we study the problem of maintaining sensing coverage by keeping a small number of active sensor nodes and a small amount of energy consumption in wireless sensor networks. This paper extends a result from [21] where only uniform sensing range among all sensors is used. We adopt an approach that allows non-uniform sensing ranges for different sensors. As opposed to the uniform sensin... View full abstract»

  • A self-stabilizing directed diffusion protocol for sensor networks

    Publication Year: 2004, Page(s):69 - 76
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB) | HTML iconHTML

    We design a self-stabilizing communication protocol in a sensor network, based on the directed diffusion method [1]. A request for data from an initiator node is broadcast in the network, and the positive answers from the sensors are forwarded back to the initiator (following a Shortest-Path- Tree (SPT) construction rooted at the initiator.) The sensor nodes, starting from an arbitrary state and f... View full abstract»

  • Hash chains with diminishing ranges for sensors

    Publication Year: 2004, Page(s):77 - 83
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (289 KB) | HTML iconHTML

    Sensors and other small devices that periodically transmit relatively small packets of information motivate the study of hash chains with small domains and ranges. Hash chain based protocols work using deferred disclosure and it is often assumed their hash functions are one-way, hence essentially unbreakable. However small domains and ranges make hash functions much weaker. If a deterministic hash... View full abstract»

  • Energy efficient organization of mobile sensor networks

    Publication Year: 2004, Page(s):84 - 91

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (281 KB) | HTML iconHTML

    One of main design issues for a sensor network is conservation of energy available at each sensor node. To increase lifetime of a sensor network, we can organize the sensors into disjoint sets so that only one set is active at a time. The lifetime of the network increases proportionally to the number of disjoint sets. In general, sensors are randomly scattered in the monitored area, thus the numbe... View full abstract»

    Smart antenna is suggested to be used in future generation wireless and mobile networks to provide service with high capacity and quality. In this paper, we propose an analytical model for a novel multimedia wireless and mobile networks using smart antennas. The smart antenna in the proposed system provides space division multiple access (SDMA) scheme in which channels can be reused in one cell an... View full abstract»

    We study the problem of handoffs in heterogeneous (both wired and wireless) networks. We first present a testbed that integrates multiple network technologies (Ethernet LAN, WiFi and GPRS cellular data network) to provide seamless connectivity to mobile hosts. We then propose a model to analyze the performance of vertical handoffs as well as experimental measures to validate the model. Finally, we... View full abstract»

    We propose a novel multicast communications model, called RingNet, which is a combination of logical trees and logical rings for multicast communications. Based on RingNet, we propose a reliable totally-ordered group multicast protocol for mobile Internet. The network entities in the top logical ring of the RingNet hierarchy are responsible for totally-ordering messages. All the network entities i... View full abstract»
