A novel model of Internet access networks is proposed, based on fog computing. The model hosts applications close to users by relying on virtual machines to dynamically move cloud or Web content to nodes located at the edge of access networks. Then it can perform proactive caching and enforce traffic policies based on the interaction between access infrastructure and external applications. By analyzing...
In this paper, we analyze the performance of vertical handover (VHO) algorithms for seamless mobility between WiFi and UMTS networks. We focus on a no-coupling scenario, characterized by the lack of any form of cooperation between the involved players (users and network operators). In this context, we first propose a low-complexity Received Signal Strength Indicator (RSSI)-based algorithm, and then...
The Internet of Things (IoT) will interconnect billions of devices, denoted as “smart objects,” deployed pervasively, which will be extremely heterogeneous, in terms of hardware (i.e., computational power and available memory), software (i.e., operating systems, applications), and communication interfaces. Traditional Internet actors, such as personal computers, mobile devices, and cloud servers,...
Recent years have seen the relentless market explosion of mobile devices, whose ever increasing capabilities (in terms of computational power, networking, and sensing) make them attractive to an endless number of connected applications and services (especially in business and infotainment domains) which can be fully experienced in mobility. This huge market growth naturally involves a constant increase...
In recent years, Vehicular Ad-hoc NETworks (VANETs) have experienced an intense development, driven by academia, industry, and public authorities. On the basis of this, it is reasonable to expect that VANETs will finally hit the market in the near future. In order to reach commercial success, VANETs must effectively operate also during the first years of deployment, when the market penetration rate...
