    Service discovery is a critical functionality of emerging pervasive computing environments. In such environments, service discovery mechanisms need to (i) overcome the heterogeneity of hardware devices, software platforms, and networking infrastructures; and (ii) provide users with an accurate selection of services that meet their current requirements. To address these issues, we have developed th... View full abstract»

  • Discovering Causal Dependencies in Mobile Context-Aware Recommenders

    Publication Year: 2006 , Page(s): 4
    Request Permissions | Click to expandAbstract | PDF file iconPDF (280 KB) |  | HTML iconHTML  

    Mobile context-aware recommender systems face unique challenges in acquiring context. Resource limitations make minimizing context acquisition a practical need, while the uncertainty inherent to the mobile environment makes missing context values a major concern. This paper introduces a scalable mechanism based on Bayesian network learning in a tiered context model to overcome both of these challe... View full abstract»

  • Context Integration for Mobile Data Tailoring

    Publication Year: 2006 , Page(s): 5
    Request Permissions | Click to expandAbstract | PDF file iconPDF (2072 KB) |  | HTML iconHTML  

    Independent, heterogeneous, distributed, sometimes transient and mobile data sources produce an enormous amount of information that should be semantically integrated and filtered, or, as we say, tailored, based on the user’s interests and context. Since both the user and the data sources can be mobile, and the communication might be unreliable, caching the information on the user device may b... View full abstract»

  • Time Geography for Ad-Hoc Shared-Ride Trip Planning

    Publication Year: 2006 , Page(s): 6
    Request Permissions | Click to expandAbstract | PDF file iconPDF (368 KB) |  | HTML iconHTML  

    Ad-hoc shared-ride trip planning is a planning task on a non-deterministic transportation network. We propose to solve this task in a mobile geosensor network, which consists of transportation clients and hosts. In a mobile geosensor network the communication costs are a critical factor. Trip planning agents need communication to collect knowledge about the current network, and any way to limit th... View full abstract»

  • An Efficient Resilience Mechanism for Data Centric Storage in Mobile Ad Hoc Networks

    Data Centric Storage (DCS) is a powerful storage paradigm for wireless ad hoc networks. In mobile ad hoc networks (MANETs), however, the mobility and varying density of nodes may significantly impact the efficiency of data access and the level of data consistency for existing DCS mechanisms. In this paper, we propose an efficient resilience mechanism for data centric storage that supports DCS in m... View full abstract»

    Emerging applications of mobile data management, such as content-based image retrieval in ad hoc networks, require the awareness of content distribution to enact and optimize the communication and search tasks. Caching is a widely used approach in mobile environments to improve system performance and keep track of replications. Within the scope of mobile and ubiquitous computing infrastructure, tr...

    In next-generation networking environments, ubiquitous networks will be available both indoors and outdoors. Various devices will be ubiquitously embedded in our homes and cityscape. Digital content will be stored not only by servers on the Internet, but also in embedded devices belonging to ubiquitous networks. In this paper, we propose a content-processing mechanism for use in environment-enabli... View full abstract»

    This paper discusses how ad-hoc collaboration boosts the operation of a set of messengers. This discussion continues the research we earlier initiated in theMESSENGER project, which develops data management mechanisms for UDDI registries of Web services using mobile users and software agents. In the current operation mode of messengers, descriptions of Web services are first, collected from UDDI r... View full abstract»

    In mobile organizations such as enterprises operating on field, healthcare organizations and military and civilian coalitions, individuals, because of the role they have, may need to access common information resources through location-aware applications. To enable a controlled and privacy preserving access to such applications, a comprehensive conceptual framework for an access control system enh... View full abstract»

    With the emergence of an infrastructure that enables the geo-positioning of on-line, mobile users, the management of so-called moving objects has emerged as an active area of research. Among the indexing techniques for efficiently answering predictive queries on moving-object positions, the recent Bx-tree is based on the B+-tree and is relatively easy to integrate into an existing DBMS. However, t... View full abstract»

  • LUGrid: Update-tolerant Grid-based Indexing for Moving Objects

    Indexing moving objects is a fundamental issue in spatiotemporal databases. In this paper, we propose an adaptive Lazy-Update Grid-based index (LUGrid, for short) that minimizes the cost of object updates. LUGrid is designed with two important features, namely, lazy insertion and lazy deletion. Lazy insertion reduces the update I/Os by adding an additional memory-resident layer over the disk index...

  • k-Closest Pair Query Monitoring Over Moving Objects

    Publication Year: 2006 , Page(s): 14
    Request Permissions | Click to expandAbstract | PDF file iconPDF (264 KB) |  | HTML iconHTML  

    k-closest pair query is a useful type of query in many practical applications involving spatial data for decision making. The traditional techniques to handle k-closest pair queries generally assume that the objects are static. In this paper, we study the problem of k-closest pair monitoring (kCPM) over moving objects. Aiming at reducing communication cost for location updates between the clients ... View full abstract»

    Short-range wireless technologies such as IEEE802.11 and Bluetooth enable mobile hosts in broadcast systems to manage cache cooperatively. In nonuniform broadcast systems, hot data are broadcast more frequently than cold data are. Cooperative cache management schemes adaptive to nonuniform broadcast are desirable. In this paper, we first propose a Keep Requesting (KR) extension for existing cooper... View full abstract»
