In ad-hoc networks, location estimation must be designed for mobility and zero-
configuration. A peer-to-peer relative location system uses pair-wise range estimates made …

Wireless networks have displaced the well established and widely deployed wired
communication networks of the past. Tetherless access and new services offered to mobile …

This paper describes an UWB location system that employs relative location principles to
provide enhanced location performance in wireless networks. The system takes advantage …

The peer-to-peer nature of a wireless sensor network presents the opportunity for accurate
and low-configuration sensor location estimation. Range measurements are made between …

In this paper, we present new analytical, simulated, and experimental results on the
performance of relative location estimation in multihop wireless sensor networks. With …

We propose a method to estimate the location of a mobile user. We assume that mobile
users carry portable devices such as laptops or personal digital assistants equipped with off …

Future mobile devices will increasingly have multiple sources of location information
associated with them, such as GPS, cellular cell-sector ID, Bluetooth or 802.11 wireless …

This paper presents a quantitative comparison of various geolocation algorithms for the
indoor wireless environment. Using models recently developed for time-of-arrival (TOA) …

This paper focuses on fundamental system deployment aspects of location estimation in
802.11-based wireless networks. We concentrate on adaptable infrastructure-based …

Wireless location refers to the geographic coordinates of a mobile subscriber in cellular or
wireless local area network (WLAN) environments. Wireless location finding has emerged …
