To provide reliable network and cloud services, it is necessary to perform precise monitoring and security analysis of cloud, ISP and local networks. Current SOHO (Small Office Home Office) devices have very limited resources and can not provide precise network security monitoring in local networks. Therefore we have designed small and low-power network probe which is able to analyse the network traffic...
The emergence of power as a first-class design constraint has fueled the proposal of a growing number of run-time power optimizations. Many of these optimizations trade-off power saving opportunity for a variable performance loss which depends on application characteristics and program phase. Furthermore, the potential benefits of these optimizations are sometimes non-additive, and it can be difficult...
Elasticity is a key component of modern cloud environments and monitoring is an essential part of this process. Monitoring demonstrates several challenges including gathering metrics from a variety of layers (infrastructure, platform, application), the need for fast processing of this data to enable efficient elasticity and the proper management of this data in order to facilitate analysis of current...
In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
Remote attestation is the procedure in which a relying party verifies the environment in which a device is carrying out cryptographic operations. Relying parties can leverage attestation data as part of their authentication and authorization procedures. However many Internet-of-Things (IoT) devices either do not have direct connectivity to relying parties, or may simply not be able to provide reliable...
In the past years, huge data is passing through internet and this demands renovation to the TCP/IP networks. Information centric network is suggested to resolve limitation of address based communication in TCP/IP network. As one of ICN architecture, data transmission in Named Data Network (NDN) is performed by address based content pulling. To pull content, packets that contains content name are forwarded...
The rapid development in communication approach has brought out new mode of communication. Among the recent developments, adhoc network has emerged as new mode of data communication. The objective of link reliability is a major concern in such network. In this paper, a new approach to route discovery based on network power and operational characteristic is proposed. The approach suggested, results...
In recent past, researchers have shown a lot of interest in Under Water Sensor Networks (UWSNs) because of its application in wide range of domains. UWSN, actually a sub body of Wireless Sensor Networks (WSN), facilitate with radio communication with high-precision of information to a sink node from any of the source node. The Role of any-casting is of significant importance in the context of routing...
In nigh application, it is indispensable to discover or supervise the behavior of the surrounding situation at a fine resolution over large spatial-temporal scales therefore WSN (Wireless Sensor Network) is well-advised. Because of smaller size and low power requirement of sensor device use of WSN for watching the surrounding action is increased time to time. Numeral of sensor inside WSN is proportionate...
Abstract-Public-cloud providers do not disclose quantitative information about the performance of their inter- datacenter networks in spite of their importance and of the growing interest they are attracting. In this paper we propose an analysis of the inter-datacenter network of the two leading providers-Amazon Web Services and Microsoft Azure- only leveraging active monitoring approaches and thus...
As cloud based platforms become more popular, it becomes an essential task for the cloud administrator to efficiently manage the costly hardware resources in the cloud environment. Prompt action should be taken whenever hardware resources are faulty, or configured and utilized in a way that causes application performance degradation, hence poor quality of service. In this paper, we propose a semantic...
Software defined networks (SDN) is perceived to have specific capabilities for utilization by network infrastructures automatically. The success of OpenFlow protocol is to decouple control plane from data plane completely. However, current SDN still regards the network as a group of devices rather than a holistic resource, and traffic monitoring and control only relies on network states but not including...
This work proposes the Quality-of-Service Monitoring and Controlling Driver (QoSMCD), a software-based mechanism that improves the Network-on-Chip (NoC) performance by controlling the packet injection rate, thus reducing link congestion without modifying the hardware. The proposed mechanism works together with the task scheduling policy for controlling the injection of packets into the NoC. This work...
In recent years, NoSQL databases have emerged as an answer to Internet scale datasets. However, these solutions do not support out of the box the necessary backup, restore and disaster recovery capabilities required by many big data scenarios. In this paper we address this gap: we present a novel disaster recovery approach designed for big data NoSQL workloads. This approach can support low recovery...
Machine breakdowns and improper maintenance management cause production systems to function inefficiently. Particularly, breakdowns cause rippling effects on other machines in terms of starved and blocked states. Effective planning of maintenance can lead to improved production system efficiency. This paper aims at improving system throughput through prioritization of maintenance work orders by continuously...
The knowledge of service performance of cloud providers is essential for cloud service users to choose the cloud services that meet their requirements. Instantaneous performance readings are accessible, but prolonged observations provide more reliable information. However, due to technical complexities and costs of monitoring services, it may not be possible to access the service performance of cloud...
Inter-application I/O contention and performance interference have been recognized as severe problems. In this work, we demonstrate, through measurement from Titan (world's No. 3 supercomputer), that high I/O variance co-exists with the fact that individual storage units remain under-utilized for the majority of the time. This motivates us to propose AID, a system that performs automatic application...
Network Function Virtualization (NFV) is a new trend in networking, where network functions are moving from custom hardware appliances to software implementations running on virtual machines (VMs) hosted on commodity hardware. While the benefits of NFV such as cost reduction and increased agility are well understood, doubts still exist on whether a software implementation can match up to the high...
The evolution of intelligent fab automation raises the opportunity of improving fab effectiveness such as product yield and machine efficiency by predicting their possible losses and taking proper actions in advance. With the huge amount of real-time data being collected in modern fab, the conventional standards and indexes defined for the yield and the productivity shall be inevitably altered in...
This article describes the design and implementation of an electronic prototype of high availability, that would facilitate the residential Internet user to have and evaluate using an interface graphic description highly reliable and detailed network parameters as bandwidth is proposed, delay, jitter, throughput and service downtime without using a commercial network manager. This way you could make...
