	abstract = {With the growing popularity of Internet-enabled devices, the impressive progress in sensing technology, and the adoption of cloud computing for provisioning services, users increasingly demand services that can adapt to their recent context. In this paper, we propose, a multi-attributes and adaptive approach for Context Level Agreements (CLAs) negotiation between a context provider and a context consumer using a context broker. The approach employs a Nash bargaining model and evaluates the global utility of each party as a linear function of normalized Quality of Context (QoC) attributes during the rounds of negotiation. The ultimate goal is to improve context-based adaptation of context-aware applications and services. One of the advantages of this approach is that it permits to resolve conflicts of interests between the context provider and the context consumer when the global utility of each party reaches a Pareto optimum.},

	abstract = {Over the last few years, we are witnessing the proliferation of mobile Internet devices (MIDs) and the wide spread adoption of cloud computing for both personal and corporate usages. These technologies are converging in what is known as mobile cloud computing (MCC) paradigm. This paradigm aims at addressing resource poverty of mobile devices. Several works investigated the challenges of mobile cloud computing. With the growing heterogeneity of mobile devices, personalization of services remains a challenging issue. In this paper, we propose a conceptual framework to address the issue of personalization in a mobile cloud computing environment. It aims at satisfying the mobile user needs and preferences for service provisioning. The mobile cloud service provider composes its service from a set of in-house services and from third party services using a composition plan, which adapts services by taking into account the user{\textquoteright}s profile and preferences.},

	abstract = {To meet their business goals, organizations are increasingly demanding services that can meet their functional and quality-of-service (QoS) requirements. In this paper, we propose a framework for service provisioning, which relies on brokered Service Level agreements (SLAs) between service consumers and service providers. The framework aims at providing support for automated SLA negotiation and management. The Service Broker of the framework carries out SLA negotiation, on behalf of service consumers, with selected service providers in multi-rounds of negotiations until an agreement or a timeout is reached. In each round, multiple SLA parameters are negotiated and both parties try to maximize their global utility functions. SLA compliance monitoring relies on the monitoring infrastructure, which provides support for independent monitoring of services by third party measurement services.},

	abstract = {With the rising popularity of Internet-enabled mobile devices, users are increasingly demanding better quality of service (QoS). However, the resources of these devices and their connectivity levels remain insufficient, even though they are improving, for offering acceptable levels of QoS to users. Cloud computing infrastructures offer large and scalable resources that allow shifting the physical location of computation and storage to the cloud. Nevertheless, the integration of mobile computing with cloud computing would not guarantee adequate levels of service for mobile users. It rather delivers scalability at the cost of higher delay and higher power consumption on the mobile device. Instead, using local resources based on users geographical locations has the potential to improve the performance and QoS for mobile users. In this paper, we present and study a centralized architecture that relies on the concept of local clouds, cloudlets, to leverage the geographical proximity of resources to mobile users and offer them a better user experience. We use a continuous time Markov-chain (CTMC) to model the different nodes of the architecture: user nodes, cloudlets, and the main cloud. We estimate the delay incurred in the proposed architecture by simulating search engine queries generated by mobile users using the CTMC state models. Initial simulation results show that the usage of a cloudlet-based architecture especially centralized architecture has an efficient gains in terms of latency delay and synchronisation mechanisms.},

However, only few works have considered the issue of load distribution in a Web services context. In this paper, we investigate three models that might be used to achieve load distribution in a Web services environment. We focus on load distribution at the operation level by considering the assignment of methods execution to appropriate Web services according to some selection policies. The experiments we have conducted using the broker-oriented model have shown that better results are obtained using the random policy for Web service selection.},

However, its application to Web services is very recent In this paper, we present WS-QoSM, it Web services QoS management architecture capable of supporting at runtime the QoS management operations, QoS provisioning and assurance in delivering Web services. Our proposed architecture is based on the commonly used notion of QoS brokerage service to mediate between service requesters and service providers. Its responsibilities include performance monitoring of Web services, implementation of Web service selection policies, and negotiation of QoS. Besides, we present a server-oriented scheme for load distribution based on the sender-initiated and receiver-initiated strategies previously used in general distributed systems.},
