This chapter formally introduces the concept of Topology Control (TC), as it is one of the most important techniques utilized to reduce energy consumption in wireless sensor networks. The chapter explains in more detail the motivations behind these algorithms and includes a discussion about where to locate the topology control algorithm within the communication protocol stack and what are the necessary or possible interactions with the adjacent layers. Finally, it includes the taxonomy of topology control that will serve as the basis for the following chapters.
