Wireless communications technologies are the platform to develop user-centric systems in a multi-device platform that allows mobility and user-friendly interaction. The development of a multi-device platform requires a common language such as Java. This book discusses two different works related with Bluetooth and GPS-GSM communication, to illustrate the capacity of Java language to develop applications that need wireless communications. Java application on the distributed system is introduced by certain keywords, design pattern, software architecture, design process and architecture for ubiquitous space. Furthermore, Java is often used as an embedded programming system, which is a combination of hardware, software, mechanical and other technical components designed to perform a dedicated function, unlike a general purposes computer. This book describes a new development framework for embedded control systems and engine calibration is presented, which supports the modelling of such systems and provides tools for the design and validation activities. An analytical method to express the resonant frequency in terms of the lumped component values is outlined as well.

Mobile and wireless networks have experienced an explosive growth during the last few years. Their impact ranges from medical, to military, to industrial, and to societal. In fact, mobile and wireless networking is gradually emerging as a discipline. The primary focus of this book is the rapidly evolving design methodologies and analytical models of wireless networks. The design, development, and analysis of wireless networks that can effectively be used in many applications remain challenging research problems due to the complexity involved. However, recent advances in wireless technology have addressed successfully many of the obstacles hindering the wide deployment of wireless networks. How to develop more efficient and reliable wireless networks and effectively model them using analytical models or simulation models remains a hot research area. The goal of the book is to serve as a reference for current design methodology and analytical models that can be used to design and analyse various wireless network systems. Important developments, new strategies, and promising analytical models for design of efficient and reliable wireless networks are presented. Important features and limitations of methods and models are identified.

Next generation wireless and mobile communication systems are rapidly evolving to satisfy the demands of various network users. Due to the great success and enormous impact of IP networks, high-speed transmission is now possible for both indoor and outdoor wireless systems, internet access and web browsing have become the ruling paradigm for next generation system. It is envisioned that new generation wireless networks and hand-held terminals will support a wide variety of multimedia services such as multimedia web browsing, video and news on demand, mobile office system, stock market information, and so on, to mobile users anywhere, anytime in an uninterrupted and seamless way with low-powered handsets. The characteristics of wireless links, as well as the desire to maintain connectivity while on the move, offer significant challenges to provisioning quality of service and the related performance is of central interest. Since the resources (such as time, frequency and code) in the wireless segments of such networks are very limited, over-dimensioning the network resource is equivalent to poor capital investment, while congestion at busy hours could mean lost calls and lost revenues. It is therefore critical for wireless network designers to utilise these resources efficiently and effectively. In response to the above demand for next generation wireless and mobile communication systems, this book aims at providing a timely and concise reference of the current activities and findings in the relevant technical fields. The primary goal is to address the key technical issues pertaining to the integrated new systems and present novel technical contributions. The book contains 14 invited chapters from prominent researchers working in this area around the world.

Offering a deeper understanding of today’s internet media and the management theory behind it Platforms are everywhere. From social media to chat, streaming, credit cards, and even bookstores, it seems like almost everything can be described as a platform. In The Platform Economy, Marc Steinberg argues that the “platformization� of capitalism has transformed everything, and it is imperative that we have a historically precise, robust understanding of this widespread concept.  Taking Japan as the key site for global platformization, Steinberg delves into that nation’s unique technological and managerial trajectory, in the process systematically examining every facet of the elusive word platform. Among the untold stories revealed here is that of the 1999 iPhone precursor, the i-mode: the world’s first widespread mobile internet platform, which became a blueprint for Apple and Google’s later dominance of the mobile market. Steinberg also charts the rise of social gaming giants GREE and Mobage, chat tools KakaoTalk, WeChat, and LINE, and video streaming site Niconico Video, as well as the development of platform theory in Japan, as part of a wider transformation of managerial theory to account for platforms as mediators of cultural life.  Analyzing platforms’ immense impact on contemporary media such as video streaming, music, and gaming, The Platform Economy fills in neglected parts of the platform story. In narrating the rise and fall of Japanese platforms, and the enduring legacy of Japanese platform theory, this book sheds light on contemporary tech titans like Facebook, Google, Apple, and Netflix, and their platform-mediated transformation of contemporary life—it is essential reading for anyone wanting to understand what capitalism is today and where it is headed.

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.
