RADAR: an in-building RF-based user location and tracking system

by Paramvir Bahl, Venkata N. Padmanabhan , 2000
"... The proliferation of mobile computing devices and local-area wireless networks has fostered a growing interest in location-aware systems and services. In this paper we present RADAR, a radio-frequency (RF) based system for locating and tracking users inside buildings. RADAR operates by recording and ..."

The design and implementation of an intentional naming system

by William Adjie-Winoto, Elliot Schwartz, Hari Balakrishnan, Jeremy Lilley - 17TH ACM SYMPOSIUM ON OPERATING SYSTEMS PRINCIPLES (SOSP '99) PUBLISHED AS OPERATING SYSTEMS REVIEW, 34(5):186--201, DEC. 1999 , 1999
"... This paper presents the design and implementation of the Intentional Naming System (INS), a resource discovery and service location system for dynamic and mobile networks of devices and computers. Such environments require a naming system that is (i) expressive, to describe and make requests based o ..."

The Cricket Location-Support System

by Nissanka B. Priyantha, Anit Chakraborty, Hari Balakrishnan , 2000
"... This paper presents the design, implementation, and evaluation of Cricket, a location-support system for in-building, mobile, locationdependent applications. It allows applications running on mobile and static nodes to learn their physical location by using listeners that hear and analyze informatio ..."

The Active Badge Location System

by Roy Want, Veronica Falcao, Jon Gibbons - ACM Transactions on Information Systems , 1992
"... cation is the `pager system'. In order to locate a person a signal is sent out by a central facility that addresses a particular receiver unit (beeper) and produces an audible signal. In addition, it may display a number to which the called-party should phone back (some systems allow a vocal me ..."

The physiology of the grid: An open grid services architecture for distributed systems integration

by Ian Foster , 2002
"... In both e-business and e-science, we often need to integrate services across distributed, heterogeneous, dynamic “virtual organizations ” formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships. This integration can be t ..."

, this architecture defines a uniform exposed service semantics (the Grid service); defines standard mechanisms for creating, naming, and discovering transient Grid service instances; provides location transparency and multiple protocol bindings for service instances; and supports integration with underlying native

A Scalable Location Service for Geographic Ad Hoc Routing,”

by Jinyang Li , John Jannotti , Douglas S J De Couto , David R Karger , Robert Morris , Jinyang Li , John Jannotti , Alfred P Sloane , Foundation Fellowship , Lucille Packard , Foundations Fellowship , Jinyang 46 , John Li , Jannotti - 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 ..."

Chord: A Scalable Peer-to-Peer Lookup Service for Internet Applications

by Ion Stoica, Robert Morris, David Karger, M. Frans Kaashoek, Hari Balakrishnan - 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 ..."

a node. Data location can be easily implemented on top of Chord by associating a key with each data item, and storing the key/data item pair at the node to which the key maps. Chord adapts efficiently as nodes join and leave the system, and can answer queries even if the system is continuously

A New Location Technique for the Active Office

by Andy Ward, Alan Jones , 1997
"... Configuration of the computing and communications systems found at home and in the workplace is a complex task that currently requires the attention of the user. Recently, researchers have begun to examine computers that would autonomously change their functionality based on observations of who or ..."
