Optimizing Query Injection from Mobile Objects to Sensor Networks

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 motion plans to do a form of opportunistic query injection. We discuss methods to optimize query injection in terms of optimal injection points and transmission ranges. Numerical simulations on coverage rate metrics are provided to support the proposed methods
