Ontology Development for Heterogeneous Sensor Network

Abstract

Recent improvements in sensor technology and lower prices change the way how we collect and process massive data in real time. A sensor Network consists of sensors implanted in an environment for collecting & transmitting data regarding changes in the environment based on the requests from controlling device or base station using wireless communication. Sensor networks are used in various applications in several domains for measuring and determining physical phenomena and natural events. Sensors enable machines to capture and observe characteristics of physical objects and features of natural incidents. Sensor network are being used in medical, military and environment monitoring applications. Query dissemination and gathering of information towards central node are important communication paradigms across all application domains. A sensor network is composed of a large number of sensor nodes that are densely deployed either inside the phenomenon or very close to it. The position of sensor nodes need not be engineered or predetermined. This allows random deployment in inaccessible terrains or disaster relief operations.
