This book constitutes the refereed proceedings of the 24th IFIP WG 5.5 Working Conference on Virtual Enterprises, PRO-VE 2023, held in Valencia, Spain, in September 2023.

The 59 papers presented in this book were carefully reviewed and selected from 119 submissions.

They provide a comprehensive overview of the major challenges in sustainability of collaborative ecosystems; risks, security and resilience in networks; collaborative value creation and services; collaborative interactions and human-centered networks; skills and enabling technologies; collaborative...

This book discusses the problems of  Physical Layer Security (PLS) in Intelligent Reflecting Surface (IRS)-assisted wireless networks.

It also discusses the corresponding methods to solve these problems in a comprehensive style.  Furthermore, some potential challenges are well analyzed.

This book is divided into 11 chapters.  Chapter 1 introduces the propagation characteristics of IRS-aided PLS communications. From Chapter 2 to Chapter 10,

The authors mainly provide deep investigations of different PLS problems of  IRS-aided wireless networks,...

This book discusses the evolution of multigate transistors, the design challenges of transistors for high-frequency applications, and the design and modeling of multigate transistors for high-frequency applications. The contents particularly focus on the cut-off frequency and maximum oscillation frequency of different multigate structures. RF stability modeling for multigate transistors is presented, which can help to understand the relation between the small-signal parameter and the physical parameter of the device for optimization. This is a useful reference to those in academia and...
