Wireless Sensor Networks (WSNs) have recently been the focus of significant amount of research. The vast majority of these studies apply to conventional WSN applications which need reliable and efficient communication of scalar event features and sensor data such as temperature, pressure, etc. However, the availability of low cost CMOS cameras and microphones has seen the development of Wireless Multimedia Sensor networks (WMSNs), which can capture multimedia content from the field. WMSN applications require processing and communication of event features in the form of multimedia. Hence, there are the additional challenges of energy efficient multimedia processing and communication in WMSN, which need to be addressed.
