Preference-Implicated Personal Data Model for Personalization Service Collaboration

Geosciences Web portals are becoming increasingly important for supporting geoscientists in their research. The GEO-SEED portal is a repository of geosciences web services metadata, represented in Resource Description Framework (RDF), which supports management and discovery by machines and automated agents. This project uses SPARQL, the W3C standard for querying RDF, to support discovery of web services. SPARQL query performance becomes more critical as the amount of RDF metadata in the repository increases. Most existing RDF storage systems are based on relational database technology. The problem with most of these systems is that their query performance is limited by the use of fixed schema mapping strategies. In this paper, we present our system, called S2ST, which addresses this issue in the context of geosciences web services metadata management. Our experiments show that S2ST provides better SPARQL performance than existing relational RDF storage systems.

Data being a quantitative or qualitative representation by which a symbolic or numerical value is indicated or represented, are used in various fields for which data collection processes are performed, based on the proposed objectives. Therefore, a data collection process was developed through a mobile application and web services, which will serve to evaluate and analyze with the help of an expert in the area, the graphomotor skills of children aged 6 to 8 years with motor disabilities. The results obtained at this stage will generate a large amount of information that will be used in the future for the definition of play activities that will complement the skills or deficiencies derived once the evaluation stage is completed, it will also be possible to implement or improve a completer and more robust database that will serve not only for graphomotor but also for different areas that work with these children.

We identify parameters impacting Web services dependability, describe the methods of dependability enhancement by redundancy in space and redundancy in time, and perform a series of experiments to evaluate the availability of Web services. To increase the availability of Web services, we employ several replication schemes and compare them with a single service. The Web services are coordinated by a replication manager. It provides a round robin algorithm for scheduling the workload of the Web services and keeps updating the availability of each Web service. The replication algorithm and the detailed system configuration are described. Experiments are performed to evaluate the resulting service availability. Modeling on the Web services with Petri-net is constructed and verified through experiments with different applications. With the parameters obtained from the experiments, the proposed model can be engaged to demonstrate the characteristics of the Web service.

Mobile device has become an essential element in our day-to-day lives, even for connecting to the Internet. Consequently, web service has become extremely important to access internet services through mobile. However, security has become a major concern in the field of Mobile Web services technology and the complexity also arises in the distribution and the integration of the web services. Now-a-days the use of mobile applications customers increases notable. Researchers put on efforts to bring out the state-of-the art in mobile web services with security for accessing web services through mobile devices. However, there is no attempt made so far to secure web services at multi-level. Now-a-days mobile web services with security only are not enough, at the same time mobile web services must be an intelligent. In this paper, we have proposed a novel architecture namely Intelligent, Integrated Secure Mobile Web Services (IISMWS) to access web services through mobile devices in a secured manner.

The resource description framework (RDF) is a language for representing information about resources on the web. However, RDF can also be used to describe other data and relationships between objects in the data. Many applications in the signal/image processing (SIP) community (such as radar imaging, electromagnetics, etc.) generate large amounts of data. Researchers would like to have online access to this data as well as the ability to easily explore and mine the data. Our application's RDF metadata representation is similar to that of a conventional database, and users can use forms to search the database, or use the standard RDF query language SPARQL, to create queries. In most cases, all the data as well as the RDF description of the data resides on secure Department of Defense (DoD) major shared resource center (MSRC) resources. In order to provide a web interface for exploring this data, we need a secure way to access the user data. Towards this goal, we use the user interface toolkit (UIT) to provide a web application that allows users to browse and search the RDF metadata of large SIP databases securely and conveniently on their desktop. The UIT uses the same Kerberos technology and Secure ID cards that are used to access all MSRC machines and provides an application programming interface (API) for building clients to access computing resources in the DoD high performance computing and modernization program (HPCMP).

The subscribers' personal information and services that mobile operators are able to provide to Web developers offer new and exciting possibilities in numerous domains. However, bringing mobile information services to the Web to enable a new generation of mobile Web services presents several research challenges on identity and privacy management. In this paper, we describe a framework for identity management in mobile services that empowers users to govern the use and release of their personal information. Our framework is based on a brokering approach that intermediates between the mobile operator's information services and the Web service providers. By leveraging on Web services, identity management infrastructure and privacy enhancing technologies, our framework provides an effective, privacy-considerate delivery of services over the mobile Web environment. This paper describes the design principles and architecture of the framework as well as the feasibility, applicability and user-experience evaluation we have carried out.

Nowadays, with the advancement in mobile technologies, the use of web services has seen an explosion in interest for mobile computing environment. However, the heavyweight nature of conventional web services to be deployed on mobile devices brings new challenges in mobile computing in the coming future. Web services technology and mobile computing domains are converging at their intersection which leads to Mobile Web Services (MWS) which enables the service access in users’ mobile device. As the numbers of web services are increasing dramatically, the web service discovery becomes more important to discover the usable web services in effective and efficient manner. This paper discusses an overview of mobile challenges in MWS recent research, and a summary of the issues. Moreover, current approaches of Mobile Web Services Discovery are classified and these approaches are compared to some criteria. The results of this study will help researchers to deliver more applicable solutions with the most appropriate approaches for Mobile Web Services Discovery.KeywordsWeb ServicesMobile Web Serviceweb service discoverymobile computingmobile web service discovery

Today, the service computing research is focusing on providing efficient solutions to the challenges of the future Internet applications. The major difference that is created by these applications is their ubiquitous on-the-move availability as cloud services. This means that the mobility is rapidly becoming a fundamental requirement of the future. In addition to that, the integration of mobile and service computing domains has enabled the existing mobile devices to offer their resources as mobile Web Services (WS). For this reason, the provisioning of mobile WS in future networks is expected to become a part of the cloud, where ubiquitous services are offered by any device. This will open new business prospects for the service providers. In this paper, we present the concept of protecting such mobile WS by using Service Level Agreements (SLA) on mobile devices. Here, we propose a framework to offer SLA negotiations and manage the Quality of Service (QoS) of the provisioned mobile WS. Furthermore, the paper explains the four primary architectural components and classifies their functions into four fundamental SLA life cycles. Also, the detailed discussion regarding each life cycle and its relation to the corresponding component(s) is provided. The research addresses some major issues of authentic and authorized access to mobile WS that might become useful as we move towards the future ubiquitous Internet.

Web services specification provides an open standard for the distributed service oriented architecture. It is widely used in Internet and pervasive networks supporting wireless mobile devices. A mobile agent is a composition of computer software and data which is able to migrate from one host to another autonomously and continue its execution on the destination host. Mobile agent technology can reduce the bandwidth requirement and tolerate the network faults - able to operate without an active connection between clients and server. Hence, the applications of the combination of mobile agents and web service have been widely investigated in recent years. However, the security issue is still of a major concern. In this paper, we propose a novel agent-based web service security scheme. This scheme provides a new authentication protocol without using the user- name/password pair, which is infeasible for mobile agent, and gives an alternative method to current security mechanism without using Certification Authorities (CA) based public key infrastructure. With this scheme, we can simplify the key management and reduce the computation particularly for group-oriented web services.

Web Services are today a well-accepted technology. Especially in the area of Cloud Computing, Web Services usually provide one of the building blocks of the used technology. Another driving technology nowadays are mobile devices. Nevertheless, there is not much research conducted yet in bringing these two important technologies together, e.g. with respect to providing Web Services on mobile devices. While there is already some technology that allows to deploy Web Services directly on mobile devices, it seems that there is still a lack of research about use-cases and/or scenarios that benefit from mobile Web Services. Therefore, this paper presents an approach that allows the evaluation of both, the technology for providing Web Service on mobile devices and mobile Web Services themselves.

The essential services such as banking, transportation, medicine, education and defense are being progressively replaced by cheaper and more efficient Internet-based web applications. Therefore, the availability of web services is very critical for the socio-economic growth of the society. Distributed denial-of-service (DDoS) attacks pose an immense threat to the availability of these services. The services are severely degraded and hence lot of business loses are incurred due to these attacks. To objectively evaluate DDoS attack's impact, its severity and the effectiveness of a potential defense, we need precise, quantitative and comprehensive DDoS impact metrics that are applicable to web services. In this paper an attempt has been made to analyze impact of DDoS attacks on the web services. The experiments are conducted in NS-2. The attack traffic is mixed with legitimate traffic at different strengths and impact of DDoS attacks are measured in terms of throughput, response time, ratio of average serve to request rate, percentage link utilization, and normal packet survival ratio (NPSR). electronic document is a live template.

In our previous research, we proposed an Autonomous Matchmaking Web Services (AMWS) framework, in which Web services broker themselves to notify the service registry whether they are suitable to the service requests. This framework is designated to more efficiently work for dynamically assembling services at runtime in a massively distributed environment. The central point of the AMWS is to use RDF (Resource Description Framework) to carry all exchanging messages. However, the implementation detail has not been discussed yet. In this paper, we focus on showing the two most important implementation parts of (1) transforming existing services to become AMWS compliant services that can consume and produce RDF messages; (2) service semantics can be annotated and self-brokered by using our developed Development Time Semantic Annotation and Lowering (DtSAL) Library at programming time.

Cloud messaging systems have emerged as fundamental infrastructure components that enable seamless communication across mobile applications, web services, and enterprise platforms on a global scale. These sophisticated distributed architectures implement advanced message processing pipelines that handle diverse communication types ranging from basic text messages to complex multimedia notifications while maintaining strict requirements for reliability, scalability, and real-time performance. The architectural framework encompasses multiple interconnected processing stages, including message ingestion, content validation, compliance verification, and delivery optimization through distributed queue-based systems. Modern implementations leverage microservices architectures with independent service components deployed across multiple availability zones, incorporating artificial intelligence for content filtering and predictive scaling capabilities. The message classification framework distinguishes between transactional and promotional communications, each requiring specialized handling protocols and compliance verification procedures. Transactional messages receive priority routing through dedicated processing lanes to ensure immediate delivery, while promotional messages undergo comprehensive filtering against regulatory requirements and user preferences. The scalability mechanisms incorporate sophisticated buffering strategies, automated failover capabilities, and intelligent load distribution across geographically distributed data centers. Fault tolerance features include redundant processing paths, automated retry logic with exponential backoff algorithms, and comprehensive message persistence strategies that ensure zero data loss during system failures or maintenance operations.

Today’s mobile devices and networks enable the development of novel mobile service applications. Developing such applications raises many challenges including heterogeneity in terms of mobile operating systems and APIs, service availability and scalability, and providing for the diverse communication needs of different applications. In this paper, we present an overview of the Odin middleware platform whose aim is to address these challenges. Odin utilises a surrogate-based architectural model to promote a mobile service’s scalability and availability. The middleware is reconfigurable, allowing mobile applications to adapt to changing operating conditions and minimise resource consumption. It also includes an optimised communication channel that masks the complexity of interacting with mobile services over mobile telecommunications networks. Using Odin’s interfaces and standards compliance, mobile applications and services with consistent communication behaviour can be easily implemented on heterogeneous platforms. Through quantitative evaluation, Odin’s message-based communication primitives have been demonstrated to perform favourably with leading industry push messaging providers.
