SENSTRAC: Scalable Querying of SENSor Networks from Mobile Platforms Using TRACking-Style Queries

Abstract

Future applications running on mobile platforms will sometimes need to query sensors and track sensor data over time. This paper uses the publish-subscribe paradigm as a natural solution to querying sensors from mobile platforms, and proposes a scalable approach to implement publish-subscribe, driven by the querying application. Our approach is evaluated by simulation, focusing on scalability
