A Framework for Simulation and Visualization of WMSNs

Wireless Sensor Networks (WSNs) contain small devices known as nodes that collect measurements from the physical environment and transmit them through the network to a central control station where they are analyzed and possibly decisions are made. Wireless Multimedia Sensor Networks (WMSN) are wirelessly connected nodes that are able to retrieve and transmit multimedia content like video and audio streams. Nodes in WMSNs are usually characterized as nodes that need to do multimedia (video/audio operations) in the most reliable and power-efficient manner. The emergence of low-cost technologies in image/video sensory (CMOS image sensors and microphones) digital signal processing as well as wireless communication have the most impact on enabling and the spread of WMSNs.
