As the number of people who interact on social networks increases, and coupled with the greater capability made available within our computational devices, there is the potential to establish “Social Clouds”—a resource sharing infrastructure that enable people who have trust relationships to come together to share computational/ data services within a community. Social clouds can also provide the...
Automatically translating textual documents from one language to another inevitably results in translation errors. In addition to language specificities, this automatic translation appears more difficult in the context of spoken dialogues since, for example, the language register is far from “clean speech”. Speech analytics suffer from these translation errors. To tackle this difficulty, a solution...
In this article, we address the problem of adapting power among users and their packet retransmissions in a downlink OFDMA context for optimizing a weighted sum throughput. Retransmission protocols are modeled using information-theoretic considerations. We propose a Constrained Markov Decision Process approach to optimize the weighted sum throughput subject to an average power constraint. Finally,...
Computing resources of Smart Space can be utilized to improve the spatial processing capabilities of other smart devices effectively. Multi-agent model based on UPnP (Universal Plug and Play) makes resource management agent discover computing resources dynamically and retrieve device information. SOA (Service-Oriented Architecture) based on WCF(Windows Communication Foundation) makes virtual services...
Information Centric Networking (ICN) has been a popular research topic in the last few years, but has not attracted industry attention because of its disruptive view; this is expected considering the evolution from PSTN to IP. Towards its adoption, ICN should not only address challenges raised by current applications, but also enable a compelling service framework for next generation of networking...
Long-Term Evolution (LTE) has now become the leading candidate for facilitating interoperability and information sharing among different types of first responders, in what has come to be commonly known as Public Safety Networks (PSNs). However, research has shown that the bandwidth assigned to these networks will not be sufficient to support the offered load and the Quality of Service (QoS) requirements...
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...
Two principles of enduring institutions for self-organising resource allocation are congruence of the allocation method to the resources available, and participation of those affected by the allocation (the appropriators) in selecting that method. However, the principles do not say anything explicitly about the fairness of the allocation method, or the outcomes. In this paper, we complement these...
In Cloud computing, when dealing with the interaction between providers and consumers, one of the main challenges is to build effective mechanisms for SLA negotiation. Such protocols must deal with different policies and objectives of the competing parties. This paper introduces and discusses protocols for SLA negotiation with multiple providers based on the ascending English auction, without requiring...
State transfer mechanisms are an essential building block in the design of many distribution applications that replicate the state, such as partially replicated databases or view-synchronous group communication. When a reconfiguration occurs, a need arises to ship a subset of objects that constitute the application state to a subset of nodes in the system. The most commonly employed solution is to...
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...
This paper presents a framework for context-driven policy-based QoS control and end-to-end resource management in converged next generation networks. The Converged Networks QoS Framework (CNQF) is being developed within the IU-ATC project, and comprises distributed functional entities whose instances co-ordinate the converged network infrastructure to facilitate scalable and efficient end-to-end QoS...
Agent technology is a good approach for solving a number of problems concerned with personalized learning. In personal learning contexts individual students are given an environment that takes into account of their needs, interests and aspirations, and this is intended to lead to an enhanced learning experience. The aim of this paper is to show how agent systems can not only form a good framework...
In the context of heterogeneous NoC architectures for embedded systems, it is today mandatory to support multiple applications given the plurality of standards and usages. While static reconfiguration between applications has already been extensively studied, we propose a potential increase in hardware resource usage by enabling concurrent or overlapping applications on the top of a heterogeneous...
In this paper, Reactive Multi-Agent Systems handle complex assignment problems as decentralized negotiating problems. Each agent locally acts in order to make the system reach a satisfying configuration. We address here, the designing problem: how to accurately communicate the problem to agents, and increase their ability to coordinate? We identify two main aspects to consider: (1) how to express...
Wireless networks will certainly run applications with strict QoS requirements and so, micro-mobility protocols such as fast hierarchical mobile IPv6 (FHMIP) are useful tools to accomplish this new feature. The FHMIP is an effective scheme to reduce Mobile IPv6 handover disruption, however it does not support application's QoS requirements. Therefore, in order to provide QoS guarantees for real-time...
Efficiency and fairness are main objectives in any system design and many choices in life are made based on their tradeoffs. In this paper we introduce a framework for the evaluation of efficiency-fairness tradeoffs that would provide a sound basis for network providers and social planners to provide or plan for an equitable access to the Internet to a diversity of users with different needs and financial...
Consistent and flexible policy and charging control is one key factor for effective access control and efficient resource management in IP-based multimedia communication networks. One approach to deal with this challenge is to put more decision logic into the so-called mediation layer which is residing between the operatorspsila core network and the charging system. This article describes our research...
Whatever the circumstances, a complete transparency and a quick response time are expected by the users of a grid even when failures occur. To fulfill these two requirements, adaptive control mechanisms have to be proposed, on one hand to cope efficiently with the dynamic changes of the computing capacity of the grid (even if these changes are unpredictable) and, on the other hand to distribute the...
