The rapid growth in market demands for high-quality, state-of-the-art, and reliable communication services increases the amount of session-control signaling, which is mainly based on the Session Initiation Protocol (SIP). Many research activities dealing with the Quality of Service (QoS) have been focused on media-related service components, whereas signaling-related service components have received...
The purpose of this research is to empirically examine the effect of third party auditor and quality service to cloud storage and user trust. This research is causal quantitative and use partial least square and path analysis. The research object is corporation users of cloud computing storage in listed corporation in Indonesia Stock Exchange. The sample size is 368 corporations and the results of...
This article is about quality of Russian service companies. The author's opinion is this level is quite low (in support of that he leads poll results). Further ISO 9001 standard is mentioned and reasons why it and statistical process control got wide recognition along manufacturers but not service sector. As a solution, a standard for automobile manufacturers ISO 16949 is taken. The approach ISO 16949...
Quality of Service is an important thing in maintaining the performance of the service to the customer. Not only for marketing purposes, the quality of services can also bridge the gap between the promise given by the service provider and what the customers get. This study aims to get the quality of service for internet data usage of several mobile operators in the city Samarinda. The study was conducted...
Middleware is the software layer that lies between applications and the devices, which make diverse vehicles exchange information transparently in Vehicular Ad Hoc Network (VANET). And the useful information can be seen as services which include web surfing, coordinated braking, runway incursion prevention, adaptive traffic control and many others. In this paper, we focus on discovering the optimal...
Using cloud computing for IT service provisioning has become a common practice over the last years. Besides basic infrastructure services, more advanced multimedia services with high Quality of Service (QoS) requirements are offered. To fulfill such requirements, appropriate cloud resources must be used for service provisioning. In this paper, we analyze different heuristic approaches to speed up...
In recent years, research has been going in the field of service composition to improvise and gain fast delivery of complex applications. These complex business processes from heterogeneous service providers are composed as services at the run time to match the requirements of the consumers. Service composition has been acknowledged as a promising approach to create composite services that are capable...
The elicitation of non-functional requirements (generic qualities of services) in the design and maintenance of services is an issue that has to be analysed under the perspective of the business (e.g. marketing, production, etc.) and information systems (e.g. requirements engineering, networks, etc.). In general, the solutions approach the final analysis service requirements at the expense of capturing...
The Cloud Computing paradigm has enabled the multi-tenancy architectural approach in Cloud applications. In a multi-tenant application, one single instance is shared by many tenants (users). Since each client has its own and particular requirements and context, that are exposed to change in time, the process of realizing customizable and adaptable services becomes complex and difficult to handle....
This paper proposes an OWL DL ontology that organizes the space of Web service into communities. The proposed ontology provides a set of key concepts: community, abstract service and concrete service and describes the relationships between them using the axioms of the description logic. Concrete services are defined as instances of communities and communities are defined as sub-concepts of the concept...
Quality of Services has an essential role throughout the process of Cloud-based web service composition for faultless and dynamic integration of business applications. Nonetheless, as Cloud-based web services grow, it becomes complicated to make possible service composition rapidly. Because web services response time can be a priceless tool for CWS (Cloud-based web service) composition satisfying...
With the development of cloud computing, many critical applications have been supported to provide many key services in the cloud computing. So the availability of cloud computing services turns to be higher and higher. Because resources of cloud computing are distributed, dynamic and heterogeneous, traditional research on availability cannot be good to adapt to the cloud computing new features. This...
Due to the very nature of modern day Smartphone's and tablets, users of such devices will often travel from an area with strong mobile signal to a weaker area. Travelling from a Strong Signal Area (SSA) to a Weak Signal Area (WSA) causes a significant drop in the mobile network bandwidth available to the device. This causes Quality of Service (QoS) problems for video streams over mobile networks....
This paper introduces a new architecture for programmable wireless interfaces, aiming at responding to the emerging request of wireless access flexibility and adaptability. Instead of implementing a specific MAC protocol stack, the proposed architecture supports a set of programmable services, devised to customize the wireless access operations according to specific network and application scenarios...
IMS (IP Multimedia Subsystem) network has high demands from perspective of multimedia, flexible and interactive communications. Fulfillment of those demands, with appropriate levels of quality, is not a simple task. As usage of services has great progress lately, there is high demand for their interaction management. Authors suggest way of Next Generation Networks application level organization and...
Cloud computing has evolved from the provisioning of virtual machines to the provisioning of complex services, delivered to customers under the terms of Service-Level Agreements (SLAs). SLAs specify the Quality of Service (QoS) that should be provided to customers as well as the billing model. A main concern for cloud service providers is to maintain the agreed SLA terms in order to avoid losses and...
There have been several efforts to provide service-aware technologies in the networks, such as Service-Oriented Architecture (SOA) and Service Delivery Platform (SDP). These technologies were integrated with Service Overlay Network (SON) infrastructure to support control and delivery of services over multiple network domains. However, SON has the limitations of handling the increasing need of ubiquitous...
Ontology is widely used to describe the semantics of web services. But the algorithms for matchmaking ontology are always so complicated that the high precision is always attained at the expense of efficiency. This paper proposes a method of matching up services on the basis of ontology's fuzzy semantics to promote the precision and efficiency at the same time. A syntactical structure is designed...
In the public perception, cloud computing is frequently associated with almost unlimited elasticity and scalability of computing capacity. However, Infrastructure as a Service in the form of virtual machines provides limited supplies of virtual resources, due to restrictions of the underlying physical hardware. At the same time, the execution of Software as a Service instances leads to a specific...
This paper focuses on a methodology for the dynamic allocation of embedded resources apt to satisfy requests of service with constraints of Quality of Service (QoS). Given a set of services provided by an embedded system, this methodology suggests how to determine the best match between a requested service and the set of Embedded subSystems (EsSs) able to provide that service. The selection of EsSs...
