Cyberinfrastructure, Science Gateways, Campus Bridging, and Cloud Computing
Computers accelerate our ability to achieve scientific
breakthroughs. As technology evolves and new research
needs come to light, the role for cyberinfrastructure as
“knowledge” infrastructure continues to expand. This
article defines and discusses cyberinfrastructure and the
related topics of science gateways and campus bridging;
identifies future challenges in cyberinfrastructure;
and discusses challenges and opportunities related to
the evolution of cyberinfrastructure, “big data” (datacentric,
data-enabled, and data-intensive research and
data analytics), and cloud computing.This material is based upon work supported by the
National Science Foundation under grants 0504075,

Long-Range Communications in Unlicensed Bands: the Rising Stars in the IoT and Smart City Scenarios
Connectivity is probably the most basic building block of the Internet of
Things (IoT) paradigm. Up to know, the two main approaches to provide data
access to the \emph{things} have been based either on multi-hop mesh networks
using short-range communication technologies in the unlicensed spectrum, or on
long-range, legacy cellular technologies, mainly 2G/GSM, operating in the
corresponding licensed frequency bands. Recently, these reference models have
been challenged by a new type of wireless connectivity, characterized by
low-rate, long-range transmission technologies in the unlicensed sub-GHz
frequency bands, used to realize access networks with star topology which are
referred to a \emph{Low-Power Wide Area Networks} (LPWANs). In this paper, we
introduce this new approach to provide connectivity in the IoT scenario,
discussing its advantages over the established paradigms in terms of
efficiency, effectiveness, and architectural design, in particular for the
typical Smart Cities applications
A Vision for Science Gateways: Bridging the Gap and Broadening the Outreach
The future for science gateways warrants exploration as we consider the possibilities that extend well beyond science and high performance computing into new interfaces, applications and user communities. In this paper, we look retrospectively at the successes of representative gateways thus far. This serves to highlight existing gaps gateways need to overcome in areas such as accessibility, usability and interoperability, and in the need for broader outreach by drawing insights from technology adoption research. We explore two particularly promising opportunities for gateways - computational social sciences and virtual reality – and make the case for the gateway community to be more intentional in engaging with users to encourage adoption and implementation, especially in the area of educational usage. We conclude with a call for focused attention on legal hurdles in order to realize the full future potential of science gateways. This paper serves as a roadmap for a vision of science gateways in the next ten years
XSEDE Campus Bridging Use Cases
This document is both a user-facing document (publicly accessible) and an internal working document intended to define user needs and use cases that fall under the general umbrella of Campus Bridging within the overall activities of XSEDE.XSEDE is supported by National Science Foundation Grant 1053575 (XSEDE: eXtreme Science and Engineering Discovery Environment)
Platforms and Protocols for the Internet of Things
Building a general architecture for the Internet of Things (IoT) is a very complex task, exacerbated by the extremely large variety of devices, link layer technologies, and services that may be involved in such a system. In this paper, we identify the main blocks of a generic IoT architecture, describing their features and requirements, and analyze the most common approaches proposed in the literature for each block. In particular, we compare three of the most important communication technologies for IoT purposes, i.e., REST, MQTT, and AMQP, and we also analyze three IoT platforms: openHAB, Sentilo, and Parse. The analysis will prove the importance of adopting an integrated approach that jointly addresses several issues and is able to flexibly accommodate the requirements of the various elements of the system. We also discuss a use case which illustrates the design challenges and the choices to make when selecting which protocols and technologies to use
