Efficient CNG Indexing in Location-Aware Sevices
In this paper, we propose and evaluate a new in-memory index structure for efficient processing of range queries over moving objects. Traditional spatial index approaches suffer from the need for frequent updates and therefore result in poor performance in moving object environments. To reduce the number of updates, many existing approaches use a linear function to represent the movement of obj...
متن کاملPrivacy-Aware Multidimensional Indexing
Deleting data from a database system in a forensic secure environment and in a high performant way is a complex challenge. Due to redundant copies and additional information stored about data items, it is not appropriate to delete only data items themselves. Additional challenges arise when using multidimensional index structures. This is because information of data items are used to index the ...
متن کاملLocation-based indexing for mobile context-aware access to a digital library
Mobile information systems need to collaborate with each other to provide seamless information access to the user. Information about the user and their context provides the points of contact between the systems. Location is the most basic user context. TIP is a mobile tourist information system that provides locationbased access to documents in the digital library Greenstone. This paper identif...
متن کاملCharged Location Aware Services
Location aware services have been envisioned as the killer application for the wireless Internet. But they did not gain sufficient attention. We are convinced that one of the major pitfalls is that there is up to now no way to charge for this kind of services. In this paper we present an architecture which provides the basic mechanisms needed to realize charged location based services. The thre...
متن کاملLocation Aware Mobile Networking
With the introduction of 3 and 4 Generation networks, the increase in WLAN hotspot population, and the approaching need to stay always best connected, intelligent roaming mechanisms are needed to homogenize wireless network connectivity and assure QoS to the end users. Additionally, the security of wireless networks and wireless devices is a necessity for the wireless world to mature, and canno...
