Localization technology has become indispensable in a wide variety of application scenarios, such as search and rescue, robotics control, node deployment and management, and location-based services. This book saves researchers and students time by scanning crucial information that is scattered throughout research journals and conference proceedings. It focuses on the localization problem and current research on this subject. The authors present measurement noise models and explore classification of localization problems based on operational environments. They also offer a detailed analysis...

Opportunistic networks forms one of the two major categories of multi-hop ad hoc networks, which are widely used in many scenarios. Applications on opportunistic networks have been on mobile network, space networks, online social networks, and underwater networks, etc. This book introduces opportunistic networking combining fundamental mathematical models, system architecture protocols, and practical applications. The book summarizes the main outcomes and investigation of opportunistic networks and provides the overview picture and system training for newcomers to this promising area.

This book covers main fiber lasers and amplifier devices based on rare-earth-doped silicia and flourozirconate fibers. It describes the erbium-doped fiber amplifier and its role as foundational in optical communication systems. This new edition is fully revised including new material on visible fluoride fiber lasers, single-frequency fiber lasers, broadband fiber sources, Qswitch fiber lasers, and rare-earth doped infrared-transmitting glass fibers. Three brand new chapters include high-power Ybdoped fiber lasers, Tm-doped mode-locked fiber lasers at 2ųm, and Ho-doped mode-locked...

This book discusses the benefits of creating Aware Networks that are a community of components with identities to support self-organizing networks, self-aware networks, and self-healing networks. The author explains how the creation of identities can neutralize numerous well-known security threats and how an infrastructure built on top of the networks will be more sustainably and better organized. Case studies provide insight into future business models and suggested security countermeasures.

These next generation standardization activities and related technical discussions are getting more and more interesting because advanced communication theories are consistently proposed, studied, discussed, and finally adopted as one of major technologies in standardization activities; e.g., millimeter-wave wireless communications, massive multiple-input-multiple-output (MIMO) wireless systems and precoding, device-to-device networking. This book introduces cutting-edge technological topics in future mobile cellular and wireless access standardization. With a solid understanding about the...

This book introduces the time domain numerical methods to solve electromagnetic problems, including finite-difference time-domain (FDTD) method, the finite element method (FEM) and method of moment (MOM). It also presents emerging methods in the recent ten years for electromagnetics simulations. All these methods can be unified under a single mathematic framework. This is one of the few books to unify and compare different time-domain methods and clarify their respective advantages and disadvantages.
