Essentials of Mobile Computing Principles

Description

Chapter 1 of this book, Essentials of Mobile Computing Principles, provides an overview of mobile computing, a brief history of the field, research obstacles, and a market vision that demonstrates the promise of mobile technology. The Internet Protocol (IP(mobile )'s IP) expansion into the mobile domain is covered in Chapter 2. Also covered are ad hoc networks and their unique needs for particular routing methods. Chapter 2 discusses the following layer, the transport layer. The present transmission control protocol (TCP), well-known from the Internet, is discussed in this chapter, along with various methods for modifying it to meet the unique needs of mobile communication systems. The most popular public mobile phone system in use today, the worldwide system for mobile communications (GSM), trunked radios, cordless phones, and the future development of the universal mobile telecommunications system, are all covered in Chapter 3. (UMTS). The fundamentals of wireless technology are explained in Chapter 4 using the traditional layers of communication systems and computer science terminology. This chapter covers modulation, multiplexing, and signal propagation. It is not necessary to have an in-depth understanding of electrical engineering, but it is necessary to understand the fundamentals of wireless transmission to comprehend the design choices made for higher-layer communication protocols and applications. Adhoc networks are shown in Chapters 5 and 6 as essential to developing wireless networks. They typically consist of identical nodes that interact wirelessly without using a centralized controller. Adhoc wireless networks take over the standard wireless and mobile communications issues, including transmission quality improvement, battery management, and bandwidth optimization. The technique for moving an active call from one base station to another as a user moves through a cellular system's coverage area is discussed in Chapter 7. It must be quick and effective to avoid a decline in service quality to an undesirable level. Chapter 8 discusses the location management issue's current fixes. The portability of mobile numbers is covered in Chapter 9. We outline and evaluate the implementation costs of number portability routing techniques. We begin by outlining the call-related and non-call-related routing approach based on the Signaling Relay Function. In Chapter 10, data management strategies for wireless mobile contexts are examined. From the data management perspective, mobile computing may vary from conventional distributed computing. There are generally two situations that could occur.
