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...

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...
