Hiking a relevant web service in the current environment full of various options is similar to looking for a needle in a haystack. The best possible web service is the one that completely fulfills the required functions while satisfying the QoS requested by a user. In this paper, we introduce a new context-based solution based on QoS (Quality of Service) exploiting both functional and non-functional...
With various connectivity and communication protocols, it is conceivable that all raw data from sensor devices can be made available in the Internet. However, this imposes a significant intricacy when dealing with the amount of information and the management of the devices. To alleviate the problem, this paper presents a design and implementation of a prototype IoT gateway framework that exposes high-level...
In this work, we propose an algorithm, called E-Learning Ontology Enrichment (ELOE), to derive a global representation from the personal ontologies of different agents present in an e-Learning MAS. Using ELOE, each agent of a MAS-based e-Learning system can autonomously enrich its own ontology by using semantic negotiation and, at the same time, it can access to the global ontology to have a view...
This work deals with Interaction Protocol (IP) adaptation for Business Processes (BP). BP describes the coordination of the actions performed by involved participants. One possible way to deal with this coordination is the use of interaction protocols (such as contract net, negotiation or vote). In order to guarantee an efficient use of IP, we need to adapt them. In this paper, we propose an MDA (Model...
Telemedicine depends on Information and Communication Technology (ICT) to support remote treatment of patients. This dependency requires the telemedicine system design to be resilient for ICT performance degradation or subsystem failures. Nevertheless, using telemedicine systems create a dependency between medical and technological concerns. We propose a layering technique that links medical and technological...
Future wireless and Internet paradigm are envisioned to be more intelligent, adaptive, recovering from transient faults and problems without service interruption, and contineously optimizing the use of resources. In this work, we present agent based network control and management framework that enables domain based dynamic policy formulation. The article discusses the proposed architecture that adapts...
With the development of Internet technologies, distributed and multimedia applications are more and more used. Because these applications have Quality of Service (QoS) expectations (bounded delay, guaranteed bandwidth, etc.), a set of QoS oriented protocols aimed at aiding end-to-end communications are proposed. Each one of these protocols offers one or several mechanisms. Selecting the best protocol...
Nowadays energy-saving represents a mandatory requirement for building. Several efforts have been done both to reduce energy consumption and to promote alternative generation sources. By the way, in most of the existing systems these two faces of energy-conservation are managed in isolation. In this paper, we propose a novel holistic vision for a smart home environment, in which energy administration...
There are many devices embedded in a smart home environment. It is a challenge to operate these devices due to the heterogeneity and the mobility of them. In this paper, we propose a context-aware resource management framework, which aims to (1) discover available resources and update the states of those devices according to the changes of contexts; (2) allocate suitable resources to meet the needs...
The tourism services are vital for the economic health of both developed and developing countries. Although the tourism services in a mobile environment have a critical role in creating tourist satisfaction, they are neither a uniform group, nor able to give consistently high service quality. Indeed they have significantly different platforms and a variety of heterogeneous service providers which...
The increasing number of Web service providers over the Web has prompted the need for research in service description and discovery. The Web service requesters need tools, in order to search suitable services that satisfy the requester's needs. The Web service discovery is defined as a mechanism that allows the service requester to gain an access to the service descriptions and make them available...
In the last years, autonomous and adaptive processes have became more and more important. Even business processes are more complex today. The more complex a system becomes, the more difficult it is to handle changed requirements. This increases the need for adaptation abilities of workflows. In these new workflow systems, autonomy would have great impact regarding the possible usability of such workflows...
Handling context-aware dynamically adaptable architectures contributes to the design of self-configuring software systems. Dealing with such a problem for communicating systems is even more challenging since adaptation should address simultaneously the different communication levels. In this paper, we address this problem by providing a model-based, rule-oriented approach that supports the adaptation...
Considering the problem of unified description of data modeling languages for computer network management, information specification ontology may be a prospective solution. However, basics of a unified mathematical theory are still lacking for ontology building. Delighted by the philosophical thinking of conceptual scheme for descriptive metaphysics, this paper tries to utilize formal concept analysis...
This paper presents a policy-based coordination model for team collaboration. Team collaboration requires an agreement that utilizes a negotiation protocol to find candidate teams and to decide on a collaboration partner. The decision relies on policies that are rules governing team situations in an organization. Contexts and rules allow reasoning about team situations. We describe a policy-based...
With the growing number of services made available, through next generation networks, it is important that end-users have easy access to the right services at the right time. This paper explores a way by which this may be achieved, namely, the recommendation of services to the end-user at an opportune time. Presented is an architecture for the recommendation of services. A possible deployment with...
