Intelligent Traffic Systems (ITS), as integrated systems including control technologies, communication technologies, vehicle sensing and vehicle electronic technologies, have provided valuable solutions to the increasingly serious traffic problems. In the process of construction and operation of ITS, big data, especially multimedia data is produced at a rapid speed, which has made traffic information...
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)...
As product of the combination of Internet technology and sensor network, Internet of things (IoT) greatly facilitates the mutual interaction of the information world and physical world. Furthermore, with the rapid development of modern transportation systems, as a typical successful application of IoT in the real life, intelligent traffic system (ITS) has a great significance on management of the...
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),...
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...
With the increasing diversity of content as well as user preferences, and the heterogeneity of devices and network technologies, content adaptation has been widely acknowledged as an effective strategy to deliver services and content to users in a variety of contexts. This paper presents an evaluation of the response time of large scale content adaptation systems being developed under the auspices...
Wireless sensor nodes have the advantages of low-cost, easy deployment and mobility. If they are deployed underground mine, with the existing underground cable transmission systems, wireless sensor network can improve the mine information greatly. The paper is to find the relationship between signal quality/packets loss rate and distance by the test in coal mine. The result can be as a reference for...
Communication systems are becoming more complex due to the advancements and heterogeneity in device and network technologies. The diversity of content and services offered to users is increasing and services have become an important source of revenue for network operators. However, the success of service providers depends on the adaptability of their services to user environments and preferences....
