Efficient retrieval of replicated data from multiple disks is a challenging problem, especially for heterogeneous storage architectures. Recently, maximum flow based optimal replica selection algorithms were proposed guaranteeing the minimum retrieval time in heterogeneous environments. Although optimality of the retrieval schedule is an important property, execution time of the replica ...

Mobile robots improve scalability and performance of wireless sensor networks. Protocols for many services including data collection, localization, topology control and security in wireless sensor networks include mobile robots. Using a single robot limits the scalability and performance and multiple robots are used as a result. When multiple robots are ...

Replicated declustering techniques reduce response times of disk requests by distributing data among multiple disks and retrieving in parallel. Efficient retrieval of replicated data from multiple disks is a challenging problem, especially for heterogeneous storage architectures receiving continuous disk requests. Existing techniques either do not consider the heterogeneity of the ...

Many applications in wireless sensor networks can benefit from position information. However, existing accurate solutions for indoor environments are costly. Radio-Frequency (RF)-based approaches are not suitable for some indoor environments such as factory floors where heavy machinery can cause interference. We propose a low-cost and simple location management system using ...

Declustering techniques reduce query response times through parallel I/O by distributing data among parallel disks. Recently, replication-based approaches were proposed to further reduce the response time. Efficient retrieval of replicated data from multiple disks is a challenging problem. Existing retrieval techniques are designed for storage arrays with identical disks, having ...

The increasing popularity of the storage cloud is leading organizations to move their applications and enterprise data into the cloud. It is desirable to move time-critical applications demanding high performance I/O operations. Flash based storage arrays have emerged to address the high performance I/O requirements, however, providing predictable Quality of ...

Efficient retrieval of replicated data from multiple disks is a challenging problem. Traditional retrieval techniques assume that replication is done at a single site using homogeneous disk arrays having no initial load or network delay. Recently, generalized retrieval algorithms are proposed to cover heterogeneous disk arrays, initial loads, and network ...

Declustering techniques reduce query response times through parallel I/O by distributing data among multiple devices. Except for a few cases, it is not possible to find declustering schemes that are optimal for all spatial range queries. As a result of this, most of the research on declustering have focused on ...

Denial of Service (DoS) attacks on a computer system or network cause loss of service to users typically by flooding a victim with many requests or by disrupting the connections between two machines. Although significant amount of work has been done on DoS attacks, DoS attacks on streaming video servers ...

Wireless sensor networks (WSNs) have been widely deployed and it is crucial to properly control the energy consumption of the sensor nodes to achieve the maximum WSNs' operation time (i.e., lifetime ) as they are normally battery powered. In this paper, for sensor nodes that are utilized to monitor oil ...

Declustering distributes data among parallel disks to reduce retrieval cost using I/O parallelism. Many schemes were proposed for single copy declustering of spatial data. Recently, declustering using replication gained a lot of interest and several schemes with different properties were proposed. It is computationally expensive to verify optimality of replication ...

obile elements, which can traverse the deployment area and convey the observed data from static sensor nodes to a base station, have been introduced for energy efficient data collection in wireless sensor networks (WSNs). However, most existing solutions only plan a single path for the mobile element, which may lead ...

Data reordering techniques are applied to improve the space and time efficiency of storage and query systems in various scientific and commercial applications. Run-length encoding is a prominent approach of compression in many areas, whose performance is significantly enhanced by achieving longer and fewer "runs" through data reordering. In this ...

Bitmap indices have been successfully used in scientific databases and data warehouses. Run-length encoding is commonly used to generate smaller size bitmaps that do not require explicit decompression for query processing. For static data sets, compression is shown to be greatly improved by data reordering techniques that generate longer and ...

A vast amount of information is being stored in scientific databases on the web. The dynamic nature of the scientific data, the cost of providing an up-to-date snapshot of the whole database, and proprietary considerations compel the database owners to hide the original data behind search interfaces. The information is ...

Port scans aim to detect the services running on a computer to find vulnerabilities of a computer. Although detecting port scans using a database system is possible, it requires too much space and computational overhead and is not feasible under high load. In this paper, we propose space-efficient structures to ...

Our work addresses the spatiotemporally varying nature of data traffic in environmental monitoring and surveillance applications. By employing a network-controlled mobile basestation (MB), we present a simple energy-efficient data collection protocol for wireless sensor networks (WSNs). In contrast to the existing MB-based solutions where WSN nodes buffer data passively until ...
