Wireless Sensor Network provides a potential technique for monitoring the indoor environment. This paper presents a Building Monitoring system based on Wireless Sensor Networks. A clustering-based network specified for building monitoring is proposed, which is inspired by LEACH (Low Energy Adaptive Cluster Hierarchy) method. Further, two key ideas are used to implement the clustering-based netw...

Clusters of PC’s are increasingly being used to build high-capacity web sites. We develop and evaluate a method of building a Single System Image (SSI) cluster that does not require a central dispatcher. In our Clone Cluster method, which builds on the existing ONE-IP method, a group of mirrored server machines with identical MAC and IP addresses are configured on a shared-medium LAN. Each mach...

Abstract. Efficient hierarchical architectures for reconfigurable and adaptive multi-agent networks require dynamic cluster formation among the set of nodes (agents). In the absence of centralised controllers, this process can be described as self-organisation of dynamic hierarchies, with multiple cluster-heads emerging as a result of inter-agent communications. Decentralised clustering algorit...

Experiments on an array of 64 globally coupled chaotic electrochemical oscillators were carried out. The array is heterogeneous due to small variations in the properties of the electrodes and there is also a small amount of noise. Over some ranges of the coupling parameter, dynamical clustering was observed. The precision-dependent cluster configuration is analyzed using hierarchical cluster tr...

Aiming at the reasonable configuration of virtual cluster and physical host, a new virtual machine cluster scheduling method is proposed. First of all, according to the resource requirements of the task, select the resource conditions similar to the virtual machine cluster. In the clustering process, the CPU, memory, communication bandwidth and other parameters are integrated in a measure under...

Configuration management is one of the largest causes of system and application failure. In one study, twenty four percent of Windows NT downtime was attributed to system configuration and maintenance [24]. Furthermore, system configuration is a large expense: 60-80% of the total cost of computer ownership is system management [6]. The problem is increasing as systems and applications get large...

Virtualization technology brings great conveniences to cluster and data center management. By using this technique, we can reconstruct a new computing environment quickly and easily. Compared to the traditional cluster environment, load balancing in a virtualized environment needs to address several new problems. This paper focuses on live migration strategies for load balancing in the virtuali...
