In multihop wireless systems, such as ad-hoc and sensor networks, the need for cooperation among nodes to relay each other’s packets exposes them to a wide range of security att...
—Data loss in wireless communications greatly affects the reconstruction quality of a signal. In the case of images, data loss results in a reduction in quality of the received i...
Wireless sensor networks (WSN) consist of small self-contained devices with computational, sensing and wireless communication capabilities. They allow flexible, powerful, tetherles...
: Railway systems are critical in many regions, and can consist of several tens of thousands of bridges, being used over several decades. It is critical to have a system to monitor...
— Accurately positioning nodes in wireless and sensor networks is important because the location of sensors is a critical input to many higher-level networking tasks. However, th...
