Design and Implementation of a Narrow-Band Intersatellite Network with Limited Onboard Resources for IoT

open access: yesSensors, 2019
Satellite networks are inevitable for the ubiquitous connectivity of M2M (machine to machine) and IoT (internet of things) devices. Advances in the miniaturization of satellite technology make networks in LEO (Low Earth Orbit) predestined to serve as a ...

A Generic Approach to Creating a National Soil Security Strategy

open access: yesSustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.
