Location-Aware Wireless Sensor Networks

摘要

There are many studies in the literature addressing various issues concerning network services of wireless sensor networks. However, these existing studies were mostly targeted at general network services in wireless sensor networks and thus failed to explore their spatial properties. The spatial properties of data, queries, and network dynamics open up new research issues. This seminar introduces research issues and the state-of-the-art solutions in location-aware wireless sensor networks. We pay special attention to the aspects on data management and spatial network services. Geographical routing (Geo-routing) protocols make routing decision based on the location information of sensor nodes, relay nodes and routing destination.
