Architecture of a Large-scale Location Service

Leonhardi, A. and Rothermel, K. 2002. Architecture of a Large-Scale Location Service. In Proceedings of the 22 Nd international Conference on Distributed Computing Systems (Icdcs’02) (July 02 – 05, 2002). ICDCS. IEEE Computer Society, Washington, DC, 465.

This paper proposes a a generic location service (LS) to manage highly dynamic location information for a large number of mobile objects. It suggests the support of multiple types of queries such as position query, range query and nearest neighborhood query, and take into consideration the accuracy of the location information. It should also hide the heterogeneity of data generated by sensor systems. In its architecture and to ensure scalability, the LS are organized in a hierarchical manner (similar to the GSM-1900). The LS is configured to cover a certain geographic area called the service area.

Relation to my thesis: A quick and easy paper that covers an IEEE approach to scalable location-aware systems. Generic location service are about heterogeneity in the sensed data, types of query, scalability (service areas), accuracy, and frequency of update message. On a similar subject (update protocols) there is A Comparison of Protocols for Updating Location Information.
