Book Description

Welcome to Real-Time Bluetooth Networks - Shape the World. This book, now in its second printing December 2017, offers a format geared towards hands-on self-paced learning. The overarching goal is to give you the student an experience with real-time operating systems that is based on the design and development of a simplified RTOS that exercises all the fundamental concepts. To keep the discourse grounded in practice we have refrained from going too deep into any one topic. We believe this will equip the student with the knowledge necessary to explore more advanced topics on their own. In essence, we will teach you the skills of the trade, but mastery is the journey you will have to undertake on your own. An operating system (OS) is layer of software that sits on top of the hardware. It manages the hardware resources so that the applications have the illusion that they own the hardware all to themselves. A real-time system is one that not only gets the correct answer but gets the correct answer at the correct time. Design and development of an OS therefore requires both, understanding the underlying architecture in terms of the interface (instruction set architecture, ISA) it provides to the software, and organizing the software to exploit this interface and present it to user applications. The decisions made in effectively managing the underlying architecture becomes more crucial in real-time systems as the performance (specifically timing) demands go beyond simple logical correctness. The architecture we will focus on is the ARM ISA, which is a very popular architecture in the embedded device ecosystem where real-time systems proliferate. A quick introduction to the ISA will be followed by specifics of TI's offering of this ISA as the Tiva and MSP432 Launchpad microcontroller. To make the development truly compelling we need a target application that has real-time constraints and multi-threading needs. To that end you will incrementally build a personal fitness device with Bluetooth connectivity. The Bluetooth connectivity will expose you to the evolving domain of Internet-of-things (IoT) where our personal fitness device running a custom RTOS will interact with a smartphone.

Book Description

Wireless Personal Area Networks provides an in-depth analysis of the recent IEEE 802.15.4 standard for low data rate wireless personal area networks (LR-WPANs), including suggestions to improve performance and comparisons with the related 802.15.1 (Bluetooth) standard. It assesses the suitability of the standard for the development and deployment of wireless sensor networks as well as providing guidance and insight into the relative advantages and disadvantages of various performance solutions. Wireless Personal Area Networks: Provides a comprehensive, in-depth look at the issues surrounding WPAN network operation and performance. Investigates multi-cluster networks and compares how they can be implemented. Analyzes the performance of a single cluster under different traffic and power management regimes including uplink vs. downlink traffic, acknowledged vs. unacknowledged traffic, saturation vs. non-saturation, and the like. Discusses security issues in WPANs such as different security threats, their impact on performance, standard security mechanisms, and security policies. Compares the IEEE 802.15.4 standard with the related Bluetooth IEEE 802.15.1 standard in terms of suitability for implementing wireless sensor networks. This reference is a valuable tool for developers and researchers getting acquainted with various aspects of IEEE 802.15.4 technology. Graduate students studying courses such as Performance Evaluation, Wireless Sensor Networks and Queuing Theory will also find this book very insightful.

Book Description

The basic idea of the real-time enterprise is to become quicker. A business which wants to become a real-time enterprise has to acquire three main abilities: - Internal and external data is integrated quickly and in real time in a well-organized company data pool, - Analyses of information in the company data pool can be obtained in real time, across function boundaries and at the touch of a button, - The number of working steps performed in batch mode is shifting dramatically in favor of immediate completion in real time. The issue of communications - or real-time communications - plays a special role here. Studies have shown that processing times sometimes double when necessary communication events are handled in batch mode in the business process and not in real time. In other words, when an activity cannot be completed and lies around for days because an urgently needed partner cannot be contacted. The necessity of acquiring these three abilities has implications for the process-related, technical and organizational aspects of a business that are dealt with in detail in this book.
