ABSTRACT
Wireless multimedia sensor networks (WMSNs) are networks of interconnected devices that allow the retrieval of video and audio streams, still images, and scalar data from the environment [1]. With the ability of providing enriched observation of the environment, WMSNs can enhance a wide range of applications such as environmental monitoring, industrial process control, traffic enforcement, and advanced health care delivery. Most WMSN applications require the delivery of multimedia information with a certain level of quality-of-service (QoS), in terms of delay, jitter, bandwidth, reliability, etc. To achieve this, one major factor that needs to be considered is the resource constraint in battery, memory, processing capability, and achievable data rate for sensor nodes.
