Supporting Cyber-Physical Systems with Wireless Sensor Networks: An Outlook of Software and Services
Sensing, communication, computation and control technologies are the essential building blocks of a cyber-physical system (CPS). Wireless sensor networks (WSNs) are a way to support CPS as they provide fine-grained spatial-temporal sensing, communication and computation at a low premium of cost and power. In this article, we explore the fundamental concepts guiding the design and implementation of WSNs. We report the latest developments in WSN software and services for meeting existing requirements and newer demands; particularly in the areas of: operating system, simulator and emulator, programming abstraction, virtualization, IP-based communication and security, time and location, and network monitoring and management. We also reflect on the ongoing
efforts in providing dependable assurances for WSN-driven CPS. Finally, we report on its applicability with a case-study on smart buildings
Pay as You Go: A Generic Crypto Tolling Architecture
The imminent pervasive adoption of vehicular communication, based on
dedicated short-range technology (ETSI ITS G5 or IEEE WAVE), 5G, or both, will
foster a richer service ecosystem for vehicular applications. The appearance of
new cryptography based solutions envisaging digital identity and currency
exchange are set to stem new approaches for existing and future challenges.
This paper presents a novel tolling architecture that harnesses the
availability of 5G C-V2X connectivity for open road tolling using smartphones,
IOTA as the digital currency and Hyperledger Indy for identity validation. An
experimental feasibility analysis is used to validate the proposed architecture
for secure, private and convenient electronic toll payment
