These interfaces allow access to SN deployed for collecting data using relational queries. However, SN are not confined to data collection, but may track object movement, e.g., wildlife observation or traffic monitoring. While rational approaches are well suited for data collection, research on Moving Object Databases (MOD) has shown that relational operators are unsuitable to express information needs on object movement, i.e., spatio-temporal queries..Querying Moving Objects Detected by Sensor Networks .studies declarative access to SN that track moving objects. The properties of SN present a straightforward application of MOD, e.g., node failures, limited detection ranges and accuracy which vary over time etc. Furthermore, point sets used to model MOD-entities like regions assume the availability of very accurate knowledge regarding the spatial extend of these entities, assuming such knowledge is unrealistic for most SN. This book is the first that defines a complete set of spatio-temporal operators for SN while taking into account their properties. Based on these operators, we systematically investigat | | 出版日期 | Book 2013 | | 关键词 | Distributed Query Processing; Moving Objects Databases; Object Detection; Sensor Networks; Spatio-Tempor | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4614-4927-0 | | isbn_softcover | 978-1-4614-4926-3 | | isbn_ebook | 978-1-4614-4927-0Series ISSN 2191-5768 Series E-ISSN 2191-5776 | | issn_series | 2191-5768 | | copyright | The Author(s) 2013 |
