• Sommario/riassunto: Two new fields have recently appeared: mobile ad hoc networks and sensor networks. The emergence of these very promising systems is mainly due to great technological progress in the field of wireless communication protocols; these will make it possible to offer a broad range of new applications in both civilian and militarian domains. The inherent characteristics of these systems imply new challenges. This book deals with several relevant fields related to the evolution of these spontaneous and self-organized networks. The authors tackle critical problems such as the design of unicast/multicas

• Sommario/riassunto: This volume is the first comprehensive handbook of Japanese phonetics and phonology describing the basic phonetic and phonological structures of modern Japanese with main focus on standard Tokyo Japanese. Its primary goal is to provide a comprehensive overview and descriptive generalizations of major phonetic and phonological phenomena in modern Japanese by reviewing important studies in the fields over the past century. It also presents a summary of interesting ; questions that remain unsolved in the literature. The volume consists of eighteen chapters in addition to an introduction to the whole volume. In addition to providing descriptive generalizations of empirical phonetic/phonological facts, this volume also aims to give an overview of major phonological theories including, but not restricted to, traditional generative phonology, lexical phonology, prosodic morphology, intonational phonology, and the more recent Optimality Theory. It also touches on theories of speech perception and production. This book serves as a comprehensive guide to Japanese phonetics and phonology for all interested in linguistics and speech sciences.
