    Distributed Storage Schemes Over Unidirectional Ring Networks

    In this paper, the authors study distributed storage problems over unidirectional ring networks. A lower bound on the reconstructing bandwidth to recover total original data for each user is proposed, and it is achievable for arbitrary parameters. If a distributed storage scheme can achieve this lower bound with equality for...

    The Failure Probability of Random Linear Network Coding for Networks

    In practice, since many communication networks are huge in scale, or complicated in structure, or even dynamic, the predesigned linear network codes based on the network topology is impossible even if the topological structure is known. Therefore, random linear network coding has been proposed as an acceptable coding technique for...

    Linear Network Error Correction Multicast/Broadcast/Dispersion Codes

    In this paper, for the purposes of information transmission and network error correction simultaneously, three classes of important linear network codes in network coding, linear multicast/broadcast/dispersion codes are generalized to linear network error correction coding, i.e., linear network error correction multicast/broadcast/dispersion codes. The authors further propose the (weakly, strongly) extended...

    Searching and Ranking XML Documents Via Path Constraints

    In this paper, the authors propose a novel method for searching and ranking XML documents via path constraints. They propose to retrieve XML data by submitting keywords with simple path constraints, which can provide users a friendly way without need of understanding complex knowledge and express user search intention accurately....

    Analysis on Data Collection With Multiple Mobile Elements in Wireless Sensor Networks

    Exploring mobile elements to conduct data collection in wireless sensor networks offers a new approach to reducing and balancing the energy consumption of sensor nodes; however, the resultant data collection latency may be large due to the limited travel speed. Many research efforts have been made on reducing the data...

    Evaluating Service Disciplines for Mobile Elements in Wireless Ad Hoc Sensor Networks

    Many applications in wireless sensor networks are data collection oriented. Data collection in sensor networks typically relies on the wireless communication between sensor nodes and the sink node, which may excessively consume the limited energy of sensor nodes due to super-linear path loss exponents. Sensor nodes near the sink also...

    CHex: An Efficient RDF Storage and Indexing Scheme for Column-Oriented Databases

    As increasingly large RDF data sets are being published on the Web, efficient RDF data management has become an essential factor in realizing the Semantic Web vision. However, most existing RDF storage schemes, which are built on top of row-store relational databases, are constrained in terms of efficiency and scalability....

    Evaluating On-Demand Data Collection With Mobile Elements in Wireless Sensor Networks

    Exploring mobility to accomplish the data collection in Wireless Sensor Networks (WSNs) has become the focus of recent studies, which can improve the energy efficiency of sensor nodes by shifting the data forwarding task from them to Mobile Elements (MEs). However, the data collection latency in this case can be...

    On the Physicl Layout of PRDT-Based NoCs

    The rapid development of VLSI technologies, as predicted in, makes it possible to integrate a large number of processing units on a single chip. One of the major challenges in designing such highly integrated System-on-Chips (SoCs) will be to find an effective way to integrate pre-designed Intellectual Property (IP) cores...
