A special issue of International Journal of Sensor Networks
With recent technological advances in communication and computation, new wireless sensor network (WSN) applications are growing. The emergence of low-energy and low-cost multimedia devices, such as microphones and cameras, has stimulated the development of the next generation WSNs, known as wireless multimedia sensor network (WMSN). WMSNs have brought unprecedented potential, especially for applications requiring ubiquitous access to the multimedia contents such as still images, audio and video streams. The extra sensor capacity and various requirements of multimedia objects in-network processing also pose new and unique challenges. These challenges are crucial about how to energy-efficiently query, process, transfer, and store voluminous multimedia objects, since most multimedia sensors are operated under limited battery power. Additionally, relatively slow advances in battery technologies mean that energy constrains the potentially fast progress in WMSNs.
This special issue will bring together those leading researchers and developers in fields of data and resource management, distributed storage techniques and energy efficiency to study the particular problems and challenges of wireless multimedia sensor networks. Its purpose is therefore to foster communications between various communities, including distributed database management communities, multimedia communication communities and sensor networks communities, and establish a common ground for advanced research and development in wireless multimedia sensor networks.
The published papers are expected to present high quality results on state-of-the-art algorithms, novel techniques and real applications associated with wireless multimedia sensor networks.
