Visual sensor networks have emerged as an important class of sensor‐based distributed
intelligent systems, with unique performance, complexity, and quality of service challenges …

A wireless sensor network with multimedia capabilities typically consists of data sensor
nodes, which sense, for instance, sound or motion, and video sensor nodes, which capture …

The availability of low-cost hardware such as CMOS cameras and microphones has fostered
the development of Wireless Multimedia Sensor Networks (WMSNs), ie, networks of …

Wireless Multimedia Sensor Networks (WMSNs) have emerged and shifted the focus from
the typical scalar wireless sensor networks to networks with multimedia devices that are …

In this paper, we propose and demonstrate a novel wireless camera network system, called
CITRIC. The core component of this system is a new hardware platform that integrates a …

In conventional sensor networks, the sensors often are based on omni-sensing model.
However, directional sensing range and sensors are great application chances, typically in …

Recent developments in low-cost CMOS cameras have created the opportunity of bringing
imaging capabilities to sensor networks. Various visual sensor platforms have been …

In many applications, it is a basic operation for the sink to periodically collect reports from all
sensors. Since the data gathering process usually proceeds for many rounds, it is important …

Unlike convectional omni-directional sensors that always have an omni-angle of sensing
range, directional sensors may have a limited angle of sensing range due to technical …

Incorporating the environment-sensing capability of wireless sensor networks into video-
based surveillance systems can provide advanced services at a lower cost than traditional …
