A Scalable Location Service for Geographic Ad Hoc Routing,”
- Proceedings of ACM/IEEE MobiCom
, 2000
"... Abstract. GLS is a new distributed location service which tracks mobile node locations. GLS combined with geographic forwarding allows the construction of ad hoc mobile networks that scale to a larger number of nodes than possible with previous work. GLS is decentralized and runs on the mobile node ..."

of node identifiers and a predefined geographic hierarchy. Queries for a mobile node's location also use the predefined identifier ordering and spatial hierarchy to find a location server for that node. Experiments using the ns simulator for up to 600 mobile nodes show that the storage and bandwidth
Chord: A Scalable Peer-to-Peer Lookup Service for Internet Applications
- SIGCOMM'01
, 2001
"... A fundamental problem that confronts peer-to-peer applications is to efficiently locate the node that stores a particular data item. This paper presents Chord, a distributed lookup protocol that addresses this problem. Chord provides support for just one operation: given a key, it maps the key onto ..."

User Cooperation Diversity -- Part I: System Description
- IEEE TRANS. COMMUN
, 1998
"... Mobile users' data rate and quality of service are limited by the fact that, within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. In this two-part paper, we propose a new form of spatial diver ..."

The R*-tree: an efficient and robust access method for points and rectangles
- INTERNATIONAL CONFERENCE ON MANAGEMENT OF DATA
, 1990
"... The R-tree, one of the most popular access methods for rectangles, is based on the heuristic optimization of the area of the enclosing rectangle in each inner node. By running numerous experiments in a standardized testbed under highly varying data, queries and operations, we were able to design the ..."

The new casper: Query processing for location services without compromising privacy
- IN PROC. OF THE 32ND INTERNATIONAL CONFERENCE ON VERY LARGE DATA BASES, VLDB
, 2006
"... In this paper, we present a new privacy-aware query processing framework Capser * in which mobile and stationary users can obtain snapshot and/or continuous location-based services without revealing their private location information. In particular, we propose a privacy-aware query processor embedde ..."
