Introduction

This part of the book is devoted to Topology Maintenance, the second component after Topology Construction to exercise Topology Control. This part consists of four chapters devoted to general aspects of topology maintenance, and topology maintenance static, dynamic, and hybrid techniques. This chapter defines topology maintenance and introduces and explains a new taxonomy. In addition, the chapter includes topology maintenance general design issues, triggering criteria, and mechanisms utilized to wake up sleeping nodes. At the end, the chapter includes a section that describes the assumptions and parameters that will be used in the performance evaluation of the different topology maintenance mechanisms introduced in subsequent chapters.
