The recent advances in MEMS, embedded systems and wireless communication technologies are making the realization and deployment of networked wireless microsensors a tangible task. Vital to the success of wireless microsensor networks is the ability of microsensors to ``collectively perform sensing and computation''. In this paper, we study one of the(More)
The recent advances in MEMS, embedded systems and wireless communication technologies are making the realization and deployment of networked wireless microsensors a tangible task. In this paper we study node localization, a component technology that would enhance the effectiveness and capabilities of this new class of networks. The n-hop multilateration(More)
—We describe the system requirements, design, system integration, and performance evaluation of the Illumimote, a new light-sensing module for wireless sensor networks. The Illumimote supports three different light-sensing modalities: incident light intensity, color intensites, and incident light angle (the angle of ray arrival from the strongest source);(More)
We present the design and implementation of the Illuminator, a preliminary sensor network-based intelligent light control system for entertainment and media production. Unlike most sensor network applications, which focus on sensing alone, a distinctive aspect of Illuminator is that it closes the loop from light sensing to lighting control. We describe the(More)
Pervasive computing's historical driver applications include environmental monitoring, safety and security, home and office productivity and guided experience of cultural activities. It also suggests and offers the means to achieve new types of expression in art and entertainment, which has not been a significant area of research despite its cultural and(More)
— With the advent of tiny networked devices, Mark Weiser's vision of a world embedded with invisible computers is coming to age. Due to their small size and relative ease of deployment, sensor networks have been utilized by zoologists, seismologists and military personnel. In this paper, we investigate the novel application of sensor networks to the film(More)
— Tasks for sensor networks often have constraints such as lifetime and latency. Performance of a sensor network like energy consumption and latency is largely affected by how the task is mapped to the nodes in network. This paper presents an energy-efficient task assignment and migration framework for sensor networks. With proposed framework, optimal task(More)
Emerging sensor network technologies will enhance entertainment production, providing both increased expressive capabilities and significant cost savings. The authors explore fundamental challenges of deploying sensor networks for production, concentrating here on feature film sets and networked sensing in support of onset activity. Film sequences are(More)
Low power consumption is an essential requirement for wireless sensor networks. In many situations un-tethered wireless sensor nodes are expected to operate on non-renewable batteries for extended periods of time. To survive in such regimes, the embedded software running on the sensor nodes should strive to optimize power consumption at the node and network(More)
