We present a structured analysis for classification of diverse mobility schemes, resulting in a taxonomy for mobility in Future Internet systems. The different approaches discussed are based on the Generic Path (GP) concept, a unified framework for the transport of information, and all of them revolve around the existence of a binding between the user and the end-to-end path. Each of the schemes is mappable to real existing and envisioned scenarios, and cover a broad type of services, such as conversational, streaming or interactive ones. As a base to this structured analysis, the work introduces the concept of Generic Path Management Record (GPMR), a flexible record capable of storing relevant information for any type of path, at any level, such as throughput, delay SNR or even authentication paramenters. Thereby, GPMR behaves as much more than a mobility tool, extending its usefulness to everything related to the Network Management universe.
Internet of things (IoT) is increasingly present in our lives. As a consequence of connecting devices, IoT can make people's lives more convenient and comfortable. However, despite unquestionable benefits offered by IoT, there is still a great deal of concern from users and companies about the security and privacy of their data. In this sense, this study conducts a qualitative study based on three case studies of companies in the IoT field, which aims to characterize how these IoT companies look at the security and privacy challenges posed by IoT. The findings allowed the authors to identify the main challenges faced by IoT companies during the past years, the main privacy risks exposed by IoT devices, and the countermeasures that companies and users can adopt to increase the security of IoT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
