The development of mobile industry promotes a deep progress of mobile applications, such as vehicular social networks (VSNs), which afford large scale data sharing between vehicles. However, trustworthiness has still been a potential security issue. Traditional public key infrastructure (PKI) cannot restrain malicious users as they are authorized in VSNs. For the reason, this paper proposes a trust...
Vehicular networks enable an efficient communication with the aim of improving data dissemination among vehicles. However, a growing number of vehicles expect to conduct data dissemination through road side facilities which cause an increment of network load. To address the issue, this letter applies fog computing technologies for enhancing vehicular network that is planned as a layered network architecture...
The mobile industry’s evolution from 4G to 5G will lead to a deep progress on mobile applications that are widely used in some new environments, such as vehicular social networks (VSNs). In VSNs, which are considered the first automobile social networks, vehicular communication can facilitate large-scale data sharing between drivers and their neighbours. However, malicious users of VSNs can also disseminate...
Infrastructure as a Service (IaaS) is a service mode of cloud, which provides Virtual Machines (VMs) to customers. With the increasingly fierce competition in market, cloud providers pay more attention to Quality of service (Qos). As the practical measurement costs a large amount of resource, deriving performance metrics from analytical model is a good choice. Recently, Stochastic Petri Net (SPN)...
Infrastructure as a service (IaaS) is a form of cloud computing, which converts physical machines (PMs) to various types of resources by virtualization technology, and delivers these resources to customers by a on-demand way. However, different customer requirements complicate the usage of resources. In this paper, we employ a high level formalization way, Performance Evaluation Process Algbra (PEPA),...
Container checkpoint is a kind of backward recovery fault tolerance technology, through which the high availability of container can be achieved. Checkpoint downtime is the key performance indicator of container checkpoint system. A long checkpoint downtime will cause users' perceptual interruption in the deployment of the service of the guest operating system in container, which is difficult to accept...
Cloud computing integrates the computation, storage, network etc., making it behaves as a virtualized computing resource pool, and provides services to customers with the dynamic on-demand and measurable way. In order to manage these resources, some cloud computing platform management systems composed of different function modules have been developed, and the coupling between these modules is very...
Analysis of Cloud workloads using data mining technology is critical for improving resource management. Unfortunately there is a lack of systematic approach to support the feature generation in comprehensive workload analysis. In this paper we propose a function based generalized feature generation method for the analysis of a one-month trace of a Google data center over 40 million task events across...
This paper studies the problem of resource management and placement for high performance clouds. It is concerned with the three most important performance metrics: response time, throughput, and utilization as Quality of Service (QoS) metrics defined in a Service Level Agreement (SLA). We propose SLA-based approaches for resource management in clouds. Specifically, we first quantify the metrics of...
Cloud computing is changing the way of developing, deploying and managing applications. However, as typical Internet-based applications, cloud computing services lack carrier-grade signaling control mechanism and cannot guaranty Quality of Service (QoS), which have actually become technical barriers for telecom operator to provide commercial public cloud services. On the other hand, as the core signaling...
