A proximity-based service (PBS) leverages the estimated proximity to provide users the accessibility to object or location restricted service. This paper exploits the interaction between Bluetooth Low Energy (BLE) Beacon and smartphone to set forth the fundamental building block of a beacon-based PBS system. In real-world scenarios, a beacon-based PBS system might suffer from sparse conditions when...
New sources of ancillary services are expected in the power system. For large and conventional generation units the dynamic response is well understood and detailed individual measurement is feasible, which factors in to the straightforward performance requirements applied today. For secure power system operation, a reliable service delivery is required, yet it may not be appropriate to apply conventional...
This paper addresses the concept of the classification of exceptional events (EE) introduced, in 2013, during the revision of the Portuguese quality of electricity supply code. An exceptional event is classified as such by the Portuguese national regulatory authority after a request from the network operator. The request must include a detailed description of the incident and the collected evidence,...
In order to effectively evaluate the next generation communication network reliability under multi-constraint Quality of Service (QoS), a reliability calculation method based on path function and ordered binary decision diagram is proposed in this paper. The link order is determined firstly by the breadth-first search and the feasible paths are calculated subsequently by decomposition and fusion based...
Over the last decade, success of social networks has significantly reshaped how people consume information. Recommendation of contents based on user profiles is well-received. However, as users become increasingly mobile, little is done to consider the constraints of the wireless environment. In this paper, we investigate a centralized wireless content delivery system, aiming to optimize overall user...
A methodology to assess the economic benefits of deploying reclosers in overhead distribution networks allowing Self-Healing strategies is advanced in this work. The developed methodology comprises a technical assessment of the service restoration feasibility through network reconfiguration and an economic assessment based on a cost-benefit analysis (CBA) over the equipment's life cycle. The economic...
With the rapid development of Web Services applications and the increasing popularity, there are numerous functionally similar Web Services available, which made the selection of the Web Services based on functional properties is insufficient. QoS is becoming an important criterion in selection for the best Web Services. In this paper, an objective and subjective QoS factors supported Web Service...
In service-oriented environment, a number of providers may offer functionally identical services with different Quality of Service (QoS). Sometimes, some providers lure customers to discover and select their services by deception. To address the unreliability of web services and other issues, we propose a reliable composite service computation framework, which integrates business process definitions...
With the development of the society, distance education and training gradually shows some characteristics similar to the service industry, such as invisible, cannot be stored, heterogeneous, serving and consuming in the same time and so on. To gain a bigger market share in competition and more reputation and brand value in development, distance education and training institutions must pay great attention...
The aim of MANET is to supply ubiquitous services through communications among a set of devices deployed in ubiquitous stub environment. Due to the dynamic characteristics of MANET and the limit of devices' capacity, it is a critical challenge to select an optimal set of device to supply high quality service constantly. In this paper, the Multi-Devices Cooperation problem is imported with ubiquitous...
Web Service is one of implementation modes of distributed systems and is becoming the next generation web-based application. As the amount of Web services is increasing, service experience problem is emerging. After Web services are implemented and published, service providers do not know their running effect and user satisfactory degree. So in order to provide better services and improve user experience...
The article proposes a model for customer satisfaction measuring, which is adapted to use in automobile industries. The proposed methodology evaluates the satisfaction level of a set of customers in different aspect of customer focus based on hypothesis values. It permits to evaluate the validity of a service/manufacturing operation from the point of view of consumers. The main advantages of this...
In this work, we establish a general framework for investigating statistical QoS provisioning in mobile ad hoc networks. Though the throughput and average delay in wireless ad hoc works have been has been intensively studied in the literature, statistical delay guarantee provisioning in large scale ad hoc networks has not received enough attention. A realtime application, e.g., interactive game and...
The paper develops a reasonable and scientific index system for the user perception of 3 G services. By top-down, breakdown by level method, the paper divides the index system into 7 dimensions(service accessibility, service retainability, service responsitivity, ease of use, Service Integrity, Quality of Sessions, Quality of Contents), formed by a number of indicators. Thus, a “dimensions - indicators...
Prior to this paper, how the airline call center employees recognize the relative importance of the service quality measurement factors categorized under SERVQUAL model has been analyzed and the findings were that they recognize the “technical quality factors,” which are categorized under the dimensions of reliability and tangibles, as same or more important than the “functional qualities factors,”...
Human dispatch as a new employing labor way greatly increases the flexibility of the enterprise employing labor and the labor resource allocation efficiency. However, the quality of service of human resource industry in china not adapts to the needs of labor units and has been the key problem of restricting the development of industry. Therefore, study on the key quality indicators affecting customer...
Achieving QoS objective in Wireless Sensor Network (WSN) that deals with multimedia information is of paramount importance in the WSN research community. From the application point of view, meeting application specific QoS constraints is equally important as designing energy efficient embedded circuitry for WSN nodes. Among various WSN communication protocol stack, the transport layer functionality...
According to the problems existing in the EigenTrust algorithm that the considered factors when local trust are little and the trust values are lack of global superiority, We proposed a new FSEM-EigenTrust algorithm based on Fuzzy Synthetic Evaluation Model. In this method, Each trading node was evaluated individually by several factors and these single values were aggregated into weighted sum, the...
The evaluation of quality of service is a credible guarantee of pervasive service, particularly, it is a key link of the supervision to the service provider in the application of healthcare pervasive service. To ensure the quality of services in pervasive computing systems, a new system PXS and a new service quality estimation method, Local Fuzzy Comprehensive Estimation (LFCE) is proposed in this...
Teaching-Aided Website (TAW) is a complex social technical system. As a result, the evaluation on TAW's service quality (SQ) is a complicated social process. The paper analyzes the characteristics of college TAW. Then it designs the evaluation index system and approach for measuring the Website's SQ. AT last, it gives the process and result of the case study on a college TAW. The data indicate that...
