In the field of wireless communication, consumption of power has become a major issue. As more and more manufacturers embed products with scatternet support, Bluetooth Low Energy (BLE) has emerged as a key technology. Although there is a need for constantly optimizing the power in BLE devices, most of the available literature is based on over-simplified power models.This thesis presents a scheme for power optimization through a Finite State Machine (FSM) modeling. In addition, a technique called role-switching between master and slaves devices, is presented. The role-switching technique happens during advertising and scanning events in a BLE connection. The work presented in this thesis deals mainly with power and performance improvements in BLE. The power reduction and performance improvements are achieved through software control, specifically due to the proposed role-switching algorithm and the FSM model.Nordic Semiconductors System on a Chip (SoC) NRF51 is used in this research as a base BLE device, and a set of experiments were performed using the proposed FSM Modeling through Gateway Sink Algorithm and the role-switching. Interaction of BLE devices with a smartphone is implemented by accessing Apple Notification Center Services (ANCS). Results show an average improvement of approximately 34.12 % for the scanning mode and 36.53 % for the connection mode in a piconet by using the role-switching algorithm.

Volume 3 of the PoC || GTFO collection--read as Proof of Concept or Get the Fuck Out--continues the series of wildly popular collections of this hacker journal. Contributions range from humorous poems to deeply technical essays bound in the form of a bible. The International Journal of Proof-of-Concept or Get The Fuck Out is a celebrated collection of short essays on computer security, reverse engineering and retrocomputing topics by many of the world's most famous hackers. This third volume contains all articles from releases 14 to 18 in the form of an actual, bound bible. Topics include how to dump the ROM from one of the most secure Sega Genesis games ever created; how to create a PDF that is also a Git repository; how to extract the Game Boy Advance BIOS ROM; how to sniff Bluetooth Low Energy communications with the BCC Micro:Bit; how to conceal ZIP Files in NES Cartridges; how to remotely exploit a TetriNET Server; and more. The journal exists to remind us of what a clever engineer can build from a box of parts and a bit of free time. Not to showcase what others have done, but to explain how they did it so that readers can do these and other clever things themselves.

This book presents breakthroughs in the design of Wireless Energy Harvesting (WEH) networks. It bridges the gap between WEH through radio waves communications and power transfer, which have largely been designed separately. The authors present an overview of the RF-EHNs including system architecture and RF energy harvesting techniques and existing applications. They also cover the idea of WEH in novel discoveries of information, the theoretical bounds in WEH, wireless sensor networks, usage of modern channel coding together with WEH, energy efficient resource allocation mechanisms, distributed self-organized energy efficient designs, delay-energy trade-off, specific protocols for energy efficient communication designs, D2D communication and energy efficiency, cooperative wireless networks, and cognitive networks.

SystemVerilog is a rich set of extensions to the IEEE 1364-2001 Verilog Hardware Description Language (Verilog HDL). These extensions address two major aspects of HDL based design. First, modeling very large designs with concise, accurate, and intuitive code. Second, writing high-level test programs to efficiently and effectively verify these large designs. This book, SystemVerilog for Design, addresses the first aspect of the SystemVerilog extensions to Verilog. Important modeling features are presented, such as two-state data types, enumerated types, user-defined types, structures, unions, and interfaces. Emphasis is placed on the proper usage of these enhancements for simulation and synthesis. A companion to this book, SystemVerilog for Verification, covers the second aspect of SystemVerilog. 'The development of the SystemVerilog language makes it easier to produce more efficient and concise descriptions of complex hardware designs. The authors of this book have been involved with the development of the language from the beginning, and who is better to learn from than those involved from day one?'
