Abstract

Edge computing is a paradigm where computation and storage services are offered by nodes that are placed close to devices that constitute the Internet of Things (IoT), as opposed to a pure cloud computing model where these services are provided by large central datacenters. The main advantages of edge computing are twofold: it allows to offer services to the IoT devices with low latency and it reduces the amount of data that needs to be sent to the central datacenters by means of data aggregation, providing significant bandwidth savings. These services are provided by edge nodes, often called fog nodes or cloudlets, that are placed in different geographical locations, close to the users. To ensure low latency the number of these servers will be necessarily high and need to be organized in a structured infrastructure that allows to take advantage of the localization of edge nodes. For the successful operation of edge computing it is crucial to have an infrastructure that is able to adapt to multiple environments and reconfigure itself to a more favorable topology. This thesis presents FlexRegMon, a system that allows to have dynamic reconfiguration of the data aggregation topology, by using a distributed component that manages the hierarchical topology of the system.
