Historic Queries in Geosensor Networks

摘要

This paper addresses—to our knowledge, for the first time—the problem of querying a geosensor network—a sensor network of mobile, location-aware nodes—for historical data. It compares different network architectures and querying strategies with respect to their performance in reconstructing events or processes that happened in the past, trying to support the hypothesis that reconstruction is possible within the limited capacities of a geosensor network only. In a concrete case study, these queries are studied in a simulated peer-to-peer ride sharing system.
