Grid computing involves enormous amount of computing resources from multiple administrative domains to fulfill the objective of resources. With the rapid growth of Internet technology, user expectations are also getting at high level in terms of performance and efficient utilization of web servers. For fulfillment of such type of user expectation, numbers of efficient and different resource allocation...
Network Functions Virtualization (NFV) Point of Presence (PoP) Data Centers are often constrained by compute and storage capacity and the cost of energy required to operate the data centers. High energy cost is a general concern for NFV operators, and in particular for specific-purpose NFV PoP DCs such as those in mobile core networks. In this context, optimized resource management and workload distribution...
Caused by the proliferation of the (IoT) and its related application domains such as Building Automation or E-Health, users face a continuously increasing amount of heterogeneous sensors and devices deployed to their environment. As a result, a large variety of protocols, data formats and physical sensing resources needs to be managed in order to gain benefit from the deployed devices. This raises...
According to analysis by Gartner, Inc., cloud computing is one of the top 10 strategic technology for most organizations in 2015. Gartner defines a strategic technology as one with the potential for significant impact on the organization in the next three years. Even though virtualization can reduce the cost of hardware equipment, but it still faces with two problems: energy consumption and the waste...
Large-scale cluster scheduling and management systems are becoming a dominant platform for a variety of applications and services. These complex “cloud” systems often run on clusters of thousands of unreliable commodity machines and mush handle all kinds of failures, schedule and deployment requirements while achieving the maximum resource utilization. We take YARN to a full analysis and argue that...
The rapid development of the Internet provides a platform for the sharing of resource, and it has become a focus of the information society with user's increasing demand for network services year by year. With the development of cloud computing technology, it provides a solution for resource sharing. But due to uncertainty of cloud computing user requests, if there is not reasonable allocation and...
Advances in biomedical and wireless technologies have flourished the development of pervasive health monitoring. Wireless Body Area Networks (WBANs) support the interoperability of biomedical sensors, communication network and medical institutions with convenience and high-efficiency, which makes it an appropriate solution for heath monitoring. In this paper, we propose Two Round Reservation MAC (2R...
In this paper, a method of analysis and design of branch waveguide coupler is discussed for power allocation, compound and monitoring. This method called even-odd mode which gives any coupling ratio and any number of branch-guide with perfectly match, high isolation and low insertion loss. The expression is deduced in the paper and according to the method, an 8dB coupler in W band is easily designed...
In virtualized environment, several computers run on a physical computer. Many of virtualization systems have a ballooning function with which memory allocation size for a virtual machine can be dynamically changed without restarting the virtual machine. Thus, it is expected that performance of an applications in a virtual machine can be improved by dynamic optimization of the virtual machine memory...
Auto scaling mechanisms have become a typical paradigm in cloud computing environments. Such mechanisms can increase or minimize the number of virtual machines according to user demands, consequently achieving pay-per-use objectives. However, auto scaling mechanisms provided by infrastructure-as-a-service providers must strictly follow user-defined thresholds, the drawback of such mechanisms is that...
This paper investigates the problem of link scheduling in a single-hop energy harvesting wireless body area network (EH-WBANs) where sensor devices's energy harvesting rates and data rates are spatially heterogeneous and temporally variant. To maximize the channel utilization with the lifetime operation, an adaptive TDMA-based protocol (AT-MAC) is proposed, which is suitable for communication in an...
The electrification of heating and transportation along with the penetration of renewable energy in electricity networks has necessitated the evolution of low voltage distribution grids into smart grids. Contemporary, smart grids are realised by smart meter installations to electricity end users. In the literature, these meters aim at online metering of the grid status. Depending on this status, proactive...
Managing a wireless sensor network is not a trivial task. Due to its limitations, such as sensors equipped with low power batteries, it is essential to extend the lifetime of the network. This task becomes harder when dealing with heterogeneous wireless sensor networks, in which sensors have different physical characteristics, such as battery capacity and radio transmission range. This paper proposes...
Power line communication necessary, should match the best ways to control. In this paper, the goal of building built on top of GIS electricity cable communication network resourcemanagement systems, analysis of the overall structure of the system. The system supports C/Sand B/S two access modes. Details of the functional modules of the system structure, keytechnology research system development. Introduction...
Nowadays, we are witnessing trends in technology, fabrication processes and computing architectures that lead to the design and development of processing systems constituted by a relevant number of independent, heterogeneous execution resources. The aim is to achieve high-performance while leveraging on other aspects, such as energy consumption. Indeed, heterogeneity comes at the cost of greater design...
Centralised management of distributed systems require a significant amount of monitoring traffic to maintain an accurate view of the system global state. The communication overhead of these systems becomes a bottleneck as the number of processing elements in the network and workload increase. State-of-the art in decentralised resource management techniques address this issue by allowing individual...
This paper introduces a novel m-trail allocation method for achieving local unambiguous failure localization (L-UFL) in all-optical mesh networks under the monitoring burst (m-burst) framework, in which a single monitoring node (MN) can localize any multi-link failure with up to d links in a (d+1)-connected network by inspecting the optical bursts traversing through the MN where each m-trails is originated...
This study attempts to upgrade the service efficiencies of cloud management by proposing different quality approaches. We design two detecting mechanisms to search the early violation signal by a different quality level of confidence. This research attempts to prevent assignable variables existed in violation situations. We proposed and verified the Moving Range Chart and EWMA Chart by utilizing CLOUDSIM...
Service Level Agreement (SLA) in cloud service provides quality and responsibility for both Data enter providers and customers. If a customer's required task is processed delayed then penalty of SLA violation are generated due to this shortage of resource allocation. The virtual machines (VMs) in lower utilization host or over utilization host will be migrated to the suitable hosts in an attempt to...
The load-balancing system, built on the basis of a subsystem load balancer and subsystem control and monitoring that closely interact with each other was propose in work. This system is presented as a queuing system with priority service discipline. In the described queuing system parallel processing flow applications occur in the multiple serving devices and successive junction of them into unified...
