1.9 Organization of this Book
This book is organized in a manner that allows a gradual progression of the subject toward more advanced topics. Chapter 2 discusses the origin of ad hoc networks, in particular, the DARPA packet radio networks. Chapter 3 presents a current version of ad hoc networks and related challenges. Since there are no static base stations present in ad hoc wireless networks, centralized access control becomes a problem. Chapter 4 presents current channel access protocols and discusses some emerging protocols. Chapter 5 provides an overview of current ad hoc mobile routing protocols, discussing their principles, features, and operation. Chapter 6 presents a new era of routing known as longevity, or associativity-based routing. This protocol is a major deviation from traditional routing protocols, which use shortest path as the main routing metric. Chapter 7 provides a narration of the implementation of an ad hoc wireless network using a new routing protocol and current-off-the-shelf (COS) hardware. It also provides a discussion of the experimental results obtained via campus field trials. Chapter 8 continues with a discussion of the communication performance of ad hoc wireless networks so that readers can understand the capabilities of such networks and what potential applications can be supported.
The advancement in CPU technology has way surpassed that of battery technology. Hence, Chapter 9 discusses how device power life can affect communication performance and protocol design for ad hoc wireless networks. Multicasting has been widely used to support multiparty communications and conferencing. Chapter 10 provides insight on how ad hoc mobile multicasting can be achieved and presents a survey of current multicasting protocols. It also reveals how associativity or longevity can be applied to ad hoc multicasting.
Since the Internet Protocol (IP) provides unreliable datagram delivery, transmission control protocol has been introduced to provide reliable delivery of information over the internet. Chapter 11 discusses the problems associated with TCP in an ad hoc wireless network environment. Ad hoc networks should provide services to users. Chapter 12 presents existing service discovery protocols that will allow an ad hoc mobile host to discover services present in the network and to access such services.
Commercial realization of ad hoc networks has taken the form of Bluetooth. Chapter 13, therefore, presents a case study of this technology. Prior to the arrival of Bluetooth, the Wireless Access Protocol (WAP) was a popular technology since it enabled a cellular network to support data in addition to voice traffic. Chapter 14, therefore, provides a discussion of WAP. Many people have been wondering about the potential applications of ad hoc networking; Chapter 15 addresses this issue. A conclusion is finally presented in Chapter 16.
