Abstract

Complex heterogeneous sensor networks that include both traditional scalar and richer video data are becoming possible. With such technologies comes the task of making them useful to the applications that rely on them. Unfortunately, such applications are extremely diverse in the interaction requirements of the system components. This paper argues that the system software for such sensor systems needs to balance optimization for performance and providing a flexible interface that can be tailored to the requirements of the user application. We propose Cascades, a cascading filter mechanism that can allow users to quickly compose and re-task diverse sensor systems (which include both scalar and video-based sensors) with highly optimized application-specific algorithms.
