A Tabu Search Algorithm for Cluster Building
in Wireless Sensor Networks


Abstract:

We propose a novel data collection approach for sensor
networks that use energy maps and QoS requirements to reduce power consumption while increasing network coverage.The mechanism comprises two phases: during the first phase, the applications specify their QoS requirements regarding the data required by the applications. They send their requests to a particular node S, called the collector node, which receives the application query and obtains result ....etc

A cluster is a type of parallel or distributed processing system, which consists of a collection of interconnected stand-alone computers co - operatively working together as a single, integrated computing resource. This cluster of computers shares common network characteristics like the same namespace and it is available to other computers on the network as a single resource. These computers are linked together using high-speed network interfaces between themselves and the actual binding together of the all the individual computers in the clust ....etc

BEOWULF CLUSTER
Abstract:
It's a kind of high-performance massively parallel computer built primarily out of commodity hardware components, running a free-software operating system like Linux or Free BSD, interconnected by a private high-speed network. Basically, the Beowulf architecture is a multi-computer architecture that is used for parallel computation applications. Therefore, Beowulf clusters are primarily meant only for processor-intensive and number-crunching applications and definitely not for storage applications. Primarily, ....etc

Terracotta is Open Source JVM-level clustering software for Java. It delivers clustering as a runtime infrastructure service, which simplifies the task of clustering a Java application immensely, by effectively clustering the JVM underneath the application, instead of clustering the application itself. Terracotta's JVM-level clustering can turn single-node, multi-threaded applications into distributed, multi-node applications, often with no code changes. Terracotta uses standard bytecode manipulation techniques to plug into the Java Memory Mod ....etc

Abstract
A computer cluster is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer. Clusters are commonly connected through fast local area networks and are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or reliability. Clusters built from open source software, particularly based on the GNU/Linux operating system, are in ....etc

Tabu Search Algorithm for Cluster Building in Wireless Sensor Networks

Abstract

The challenge in wireless sensor network deployment pertains to optimizing energy consumption when collecting data from sensor nodes. This paper proposes a new centralized clustering method for a data collection mechanism in wireless sensor networks, which is based on network energy maps and quality-of-service (QoS) requirements. The clustering problem is modeled as a hypergraph partitioning and its resolution is based on a tabu search heuristic. Our approach ....etc

FEBA: A Bandwidth Allocation Algorithm for Service Differentiation in IEEE 802.16 Mesh Networks
Cicconetti, C. Akyildiz, I. F. Lenzini, L.
This paper appears in: Networking, IEEE/ACM Transactions on Publication
Abstract
In wireless mesh networks, the end-to-end throughput of traffic flows depends on the path length, i.e., the higher the number of hops, the lower becomes the throughput. In this paper, a fair end-to-end bandwidth allocation (FEBA) algorithm is introduced to solve this problem. FEBA is implemented at the medium ac ....etc

Design Of Cluster Logical Volume Manager

Abstract :

In an open systems environment, logical volume manager (LVM) virtualizes storage by consolidating physical storage into logical volumes, which are available to applications or file systems. LVMs are available on most Unix platforms (including Linux) and on Windows 2000. By assembling virtual storage volumes out of numerous physical devices, you can create storage configurations tuned for specific applications, without the limitations of specific hardware devices. Instead, you can make ....etc

HBA DISTRIBUTED METADATA MANAGEMENT FOR LARGE SCALE CLUSTER BASED STORAGE SYSTEM

Abstract: An efficient and distributed scheme for file mapping or file lookup is critical in decentralizing metadata management within a group of metadata servers, here the technique used called HIERARCHICAL BLOOM FILTER ARRAYS (HBA) to map filenames to the metadata servers holding their metadata. The Bloom filter arrays with different levels of accuracies are used on each metadata server. The first one with low accuracy and used to capture the destination metad ....etc

Definition
The recent advances in high-speed networks and improved microprocessor performance are making clusters or networks of workstations an appealing vehicle for cost effective parallel computing. Clusters built using commodity hardware and software components are playing a major role in redefining the concept of supercomputing.
