ABSTRACT
The advancement in wireless communication and electronics has enabled the development of low-costwireless sensor networks. Especially, the productionof cheap complementarymetal-oxidesemiconductor (CMOS) cameras andmicrophones,which are able to capture richmultimedia content, have fueled a new research and development area, that of wireless multimedia sensor networks (WMSNs). WMSNs will boost the capabilities of current wireless sensor networks (WSNs), and several novel applications, like multimedia surveillance sensor networks, storage of relevant activities, and so on, will be developed. WMSNs introduce several new research challenges, mainly related to mechanisms to deliver application-level quality-of-service (QoS) (e.g., latency minimization). Such issues have almost completely been ignored in traditional WSNs, where the research focused on energy consumption minimization.
