Enhancing IoT service delivery A layered fog archictecture approach for sencing and actuating as a service

Abstract

newline The increasing amount of objects connected to the internet using various newlinepreexisting technologies for communication, storage, ubiquitous and pervasive newlinecomputing, wireless sensor networks etc, are considered as the Internet newlineof Things (IoT). This emerging technology is defined by the interconnection newlineof different types of smart objects Things provided with sensing, newlineactuating and communication capabilities to interact with their environment newlineand with each other. IoT is the enabler for connecting the physical newlinedevices to the digital world, making numerous physical devices connected newlineto the internet and allowing remote control and heterogeneous devices collaboration. newlineThis made such devices to be an essential component for several newlineecosystem applications. Several works have been proposed in the newlineliterature for IoT. These works considered standards, reference models, newlinearchitectures, and communication protocols, etc. In this thesis, the focus newlinein on IoT architectures. newlineIoT has become the backbone towards realizing smart cities and their newlineecosystems. Academia and industry have gone a long way in this a path newlinethat it has become a reality. Smart cities require a different way of thinking newlineto make several ecosystems, authorities, and ownerships collaborate and newlinework together smoothly and automatically with less human interactions. newlineThis thesis includes a proposed vision for smart city service providers towards newlinesuch a goal. newlineThe cloud paradigm has been a revolutionary computing model in the newlinelast decade. It provides a highly virtualized infrastructure with powerful newlinecomputing hardware and software resources in the form of services newlineiii
