Abstract

Tiered systems comprised of low-power, resource constrained sensor devices (motes) and higher powered microservers are quickly becoming a reality. A typical deployment scenario would consist of several microserver-class devices, each of which would be responsible for a set of motes. Mote clustering is a set of tools and services that enables interoperation between motes and microservers, thereby allowing applications to seamlessly use the available hardware infrastructure in order to achieve their task. In particular, the goal is to leverage the computational power of the microservers, as well as the higher quality state view (in terms of both temporal and spatial resolution). One of the driving applications behind mote clustering is flexible triggering of imagers. This will be comprised of a collection of microservers with cameras attached to them, as well as a deployment of motes. The motes would sense the environment and trigger the cameras when something of interest is detected. Using mote herding, the application can associate mote locations and camera fields of view as well as locate the appropriate camera for each task.
