A Probabilistic Framework for Automatic and Dependable Adaptation in Dynamic Environmentsdependabilityadaptationprobabilistic analysisquality of serviceReviewed by Miguel P. CorreiaDistributed protocols executing in uncertain environments, like the Internet, had better adapt dynamically to environment changes in order to preserve QoS. In earlier work, it was shown that QoS adaptation should be dependable, if correctness of protocol properties is to be maintained. More recently, some ideas concerning specific strategies and methodologies for improving QoS adaptation have been proposed. In this paper we describe a complete framework for dependable QoS adaptation. We assume that during its life-time, a system alternates periods where its temporal behavior is well characterized, with transition periods during which a variation of the environment conditions occurs. Our method is based on the following: if the environment is generically characterized in analytical terms, and we can detect the alternation of these stable and transient phases, we can improve the effectiveness and dependability of QoS adaptation. To prove our point we provide detailed evaluation results of the proposed solutions. Our evaluation is based on synthetic data flows generated from probabilistic distributions, as well as on real data traces collected in various Internet-based environments. Our results show that the proposed strategies can indeed be effective, allowing protocols to adapt to the available QoS in a dependable way.EC project IST-FP6-STREP-26979 (HIDENETS), and FCT, through the Multiannual and CMU-Portugal programmes.Repositório da Universidade de LisboaDixit, MônicaCasimiro, AntónioVerissimo, PauloLollini, PaoloBondavalli, Andrea2009-12-15T13:45:05Z2009-12-15T13:45:05Z2009-12-15info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/reportapplication/pdfhttp://hdl.handle.net/10451/14263enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T15:59:58Zoai:repositorio.ul.pt:10451/14263Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:36:04.787136Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
