@article {Badidi2017611, title = {Towards data-as-a-service provisioning with high-quality data}, journal = {Lecture Notes in Electrical Engineering}, volume = {397}, year = {2017}, note = {cited By 0}, pages = {611-623}, abstract = {Given the large amount of sensed data by IoT devices and various wireless sensor networks, traditional data services lack the necessary resources to store and process that data, as well as to disseminate high-quality data to a variety of potential consumers. In this paper, we propose a framework for Data as a Service (DaaS) provisioning, which relies on deploying DaaS services on the cloud and using a DaaS agency to mediate between data consumers and DaaS services using a publish/subscribe model. Furthermore, we describe a decision algorithm for the selection of appropriate DaaS services that can fulfill consumers{\textquoteright} requests for high-quality data. One of the benefits of the proposed approach is the elasticity of the cloud resources used by DaaS services. Moreover, the selection algorithm allows ranking DaaS services by matching their quality-of-data (QoD) offers against the QoD needs of the data consumer. {\textcopyright} Springer Science+Business Media Singapore 2017.}, doi = {10.1007/978-981-10-1627-1_48}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84996995662\&doi=10.1007\%2f978-981-10-1627-1_48\&partnerID=40\&md5=3699ddd8367859bcdb3853679e370f5f}, author = {Badidi, E.a and Routaib, H.b and El Koutbi, M.b} } @conference {Badidi2014601, title = {A framework for automated SLAs management in service-oriented environments}, booktitle = {International Conference on Multimedia Computing and Systems -Proceedings}, year = {2014}, note = {cited By 0}, pages = {601-606}, 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. {\textcopyright} 2014 IEEE.}, doi = {10.1109/ICMCS.2014.6911351}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84928746951\&doi=10.1109\%2fICMCS.2014.6911351\&partnerID=40\&md5=c66351ac0a2c12a5dc7d1e8211f5cb48}, author = {Badidi, E.a and El Koutbi, M.b} }
