Spatio-temporal context-aware collaborative QoS prediction

Future Generation Computer Systems, 2019
Abstract With the exponential growth of Web services, various collaborative QoS prediction methods have been suggested to make an efficient evaluation of quality-of-services (QoS) and assist users selecting appropriate services. It is still a technical challenge to be taken into account the impact of complex spatio-temporal contexts of service ...

CAPred: A Prediction Model for Timely QoS

2015 IEEE International Conference on Web Services, 2015
With the rapidly growing number of Web services, how to identify high quality Web services becomes a hot research topic. User-side QoS evaluation on Web services is a key measurement to choose the optimal Web service from a set of Web services with similar functions.

Skyline Service Selection Based on QoS Prediction

2016 IEEE International Conference on Cluster Computing (CLUSTER), 2016
In this paper, we propose a Skyline service selection approach based on QoS prediction. We first consider the QoS history records as time series and predict the QoS values by using Autoregressive Integrated Moving Average (ARIMA) model to provide more accurate QoS attributes values.

Prediction Based QoS Routing in MANETs

2006
The aim of this work is to propose a QoS routing algorithm in MANETs. The proposed algorithm predicts the future states of nodes including buffer level and position. Predicting the future state of node, the algorithm could decide whether a node is a good selection as a router or not.

Multi-Dimensional QoS Prediction for Service Recommendations

IEEE Transactions on Services Computing, 2019
Advances in mobile Internet technology have enabled the clients of Web services to be able to keep their service sessions alive while they are on the move. Since the services consumed by a mobile client may be different over time due to client location changes, a multi-dimensional spatiotemporal model is necessary for analyzing the service consumption ...

Time-Aware Model-Based QoS Prediction

2017
The exponential growth of Web service makes building high-quality service-oriented applications an urgent and crucial research problem. User-side QoS evaluations of Web services are critical for selecting the optimal Web service from a set of functionally equivalent service candidates.

Quantitative Evaluation of QoS Prediction in IoT

2017 47th Annual IEEE/IFIP International Conference on Dependable Systems and Networks Workshops (DSN-W), 2017
Internet of Things (IoT) applications, are typically built from services provided by heterogeneous devices, which are potentially resource constrained and/or mobile. These services and applications are widespread and a key research question is how to predict user side quality of service (QoS), to ensure optimal selection and composition of services ...

QoS routing with mobility prediction in MANET

2001 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (IEEE Cat. No.01CH37233), 2002
A Mobile Ad hoc NETwork (MANET) is a collection of wireless mobile hosts that form a temporary network without a centralized administration or wired infrastructure. Because of its dynamic topology, a MANET's routing protocol is different from other networks.

QoS Prediction Methods in IoT A Survey

2019 IEEE International Conference on Big Data (Big Data), 2019
Emergence of Internet of Things (IoT) concept is expected to deeply change everyday life through a vast number of services and applications. Heterogeneity of IoT networks and unique characteristics of individual services, causes requirement of different quality factors for services and applications.
