Best Paper IEEE/IFIP Network Operations and Management Symposium (NOMS): Experience Track 2014
My goal is to establish the theoretical, conceptual and algorithmic techniques that will enable the achievement of sustainable and manageable interoperability between heterogeneous systems. In order to provide insights into the concrete problems that need to be solved by my techniques, I have focused upon application spaces where hetereogenity of models need to be overcome in an ongoing and sustainable manner in order for services to be delivered. In particular over the last few years the strategy has been to focus on environments: that deliver end to end services in telecoms environments; that deliver ubiquitous computing services within built environments; and that deliver mult-lingual content within the web environment.
