Abstract

Synchronization refers to the process of achieving and maintaining coordination among independent local clocks via the exchange of local time information. Different synchronization schemes differ in the way such information is encoded, exchanged, and processed by the clocks toward the end of overcoming the unavoidable nuisance effects of inaccurate clocks and propagation/processing delays. Wireless communications provide the natural platform for the exchange of local time information between synchronizing clocks. Conversely, synchronization of local clocks enables a wealth of signal processing and communication applications in wireless networks. It is this mutual link between synchronization and wireless networks, with emphasis on decentralized structures such as ad hoc and sensor networks, that constitutes the main subject of this article. © 2008 IEEE.
