Fundamentals Of Mobile Computing

About The Book

In this book; The first chapter provides an overview of mobile computing, discussing its origins, current state of research, and future business prospects. Mobile IP, the adaptation of IP for use on mobile devices, is the topic of Chapter 2. We also talk about ad-hoc networks and the special routing techniques they need. Transport layer, the next layer, is discussed in detail in Chapter 2. In this chapter, we'll look at various strategies for modifying the present transmission control protocol (TCP), widely used on the Internet, to meet the unique needs of mobile communication networks. In Chapter 3, we cover the current most popular public mobile phone system, the worldwide system for mobile communications (GSM), as well as cordless phone technology, trunked radios, and the evolution toward the universal mobile telecommunications system (UMTS). As with other communication systems, wireless technology is broken down into its component parts and explained in Chapter 4 from a computer science perspective, which follows the classical levels of communication. Propagation, multiplexing, and modulation of signals are discussed here. The design choices made in upper layer communication protocols and applications can be understood without in-depth understanding of electrical engineering, but only if one first understands the fundamentals of wireless transmission. The importance of Ad hoc networks to the future of wireless networks is demonstrated in chapters 5 and 6. Typically, they are made up of autonomous nodes that coordinate their activities through wireless connections and operate independently of one another. Traditional issues in wireless and mobile communications, such as optimising bandwidth, regulating power consumption, and boosting transmission quality, are inherited by ad hoc wireless networks. In Chapter 7, we learn about Handoff, which is the process by which a user's active call is transferred from one base station to another when they travel inside the cellular network's service region. It needs to be quick and effective to keep service quality from plummeting. The eighth chapter analyses how the problem of location management has previously been addressed. Mobility number portability is introduced in Chapter 9. We break down the components of number portability routing methods and the expenses associated with putting them into action. We begin by outlining the solution for both call-related and unrelated routing that is based on the Signaling Relay Function. Data management strategies in mobile and wireless settings are surveyed in Chapter 10. When viewed through the lens of data management, mobile computing has parallels to more conventional forms of distributed computing. Two general outcomes are doable.
