Wireless sensor networks (WSNs) are a special class of ad hoc network in which network nodes composed of tiny sensors pass data such as temperature, pressure, and humidity through the network to a central location. Wireless sensor multimedia networks (WSMNs) are a special category of WSNs in which the sensor nodes are small cameras and microphones that can send voice, image, or video data through the network. This book presents the latest advances and research in WSMN architecture, algorithms, and protocols. WSMNs are attracting great attention from academia and industry due to the variety of applications in which they can be deployed. Wireless Sensor Multimedia Networks: Architectures, Protocols, and Applications explores the many benefits of WSMNs and the variety of applications in which they can be used-surveillance, traffic monitoring, advanced healthcare (blood pressure and heart rate monitoring), habitat monitoring, and localization services (finding missing children or wanted criminals). The contributed chapters in this book explore current research into key areas such as New quality-of-service-aware routing protocols that support a high data rate in WSMNs Cognitive radio capability that increases efficiency of spectrum utilization and decreases the probability of collision and contention Multimedia streaming optimization techniques New security schemes for real-time video streaming Various ways of optimizing power consumption in WSMNs Wireless Sensor Multimedia Networks: Architectures, Protocols, and Applications discusses open research issues and future trends in WSMNs. With this book, academic researchers, engineers, and graduate students will be well-equipped to advance the research in this emerging field.

Optical networks present a promising candidate for the next generation ultra-high-speed networks due to its potential ability to offer huge bandwidth at low costs. These networks should have the ability to maintain service continuity to end-users in presence of network failures. Therefore, survivability has become a critical issue for the next generation optical networks. In this book, we demonstrate the stat of the art survivability techniques used in highly-survivable optical networks with focus on restoration techniques as promising techniques in terms of capacity utilization and blocking probability. Mohamed A. Azim distinctive approach, explores a new survivability scheme employed in optical networks namely, Active Restoration (AR). The AR scheme combines the advantages of the proactive protection and reactive restoration techniques while trying to avoid their shortcomings as verified by extensive simulations and analytical models. The book presents a step-by-step guide to survivability techniques and analytical modeling that can help researchers to find relevant ideas and open research problems on network survivability as well as developing their analytical models.
