An interplay between mobile devices and static sensor nodes is envisioned in the near future. This will enable a heterogeneous design space that can offset the stringent resource and power constraints encountered in traditional static sensor networks by taking advantage of the more powerful mobile devices. As such, we present a systematic framework for end-to-end query processing, using a two-layer...
To facilitate flexible data discovery, sensor networks can be supported by query processing, where a query is injected into the sensor network from some base station. In his paper we consider the problem of query injection by base stations that are mobile (mobile objects) and individual sensors are "location-ignorant". The idea is to have mobile objects take advantage of each other's independent...
