A GPS-less, outdoor, self-positioning method for wireless sensor networks

Paired Measurement Localization: A Robust Approach for Wireless Localization

A theoretical localization framework in the presence of noise is postulated, which achieves accurate positioning compared to the existing theoretical approaches, and the paired measurement localization (PML) strategy is evaluated through simulations under various noise conditions and environmental modeling and practically verified by a testbed implementation with real motes.

A high-accuracy, low-cost localization system for wireless sensor networks

This paper formally describes, design, implement and evaluates a novel localization system, called Spotlight, which uses the spatio-temporal properties of well controlled events in the network, to obtain the locations of sensor nodes.

Self-Localization Techniques for Wireless Sensor Networks

This paper considers the problem of cooperative localization in which some small number of sensors, called seeds act as reference nodes, with known location, and the rest, un-localized nodes, are cooperating to determine their own coordinates.

Localization of wireless sensor networks with a mobile beacon

This work presents a localization technique based on a single mobile beacon aware of its position, and thus no extra hardware is necessary, and the accuracy is sufficient for most applications.

Algorithmic Aspects of Sensor Localization

This chapter takes a close look at the algorithmic aspects of various important localization techniques for WSNs, including graph-theoretic, geometric, statistical, optimization, and machine learning techniques.

Analytic Study on Object Localization Systems

This paper presents an analytical study of several algorithms and performance measure that used to locate the sensor nodes and also review some applications and simulators for these algorithms.

ALT provides a pin point location information to the Sensor Nodes (SNs) without any expense of cost or power and introduces the concept of location aware IDs for SNs, which will be highly advantageous for applications with large number of SN deployments where maintaining a unique ID for each node is difficult.

GPS-Free node localization in mobile wireless sensor networks

This work proposes an algorithm for directional node localization based on relative motion of neighboring nodes in an ad-hoc sensor network without an infrastructure of global positioning systems, anchor points, or even mobile seeds with known locations and demonstrates that it scales well for large numbers of nodes and provides convergent localization over time.

Scalable, Ad Hoc Deployable, RF-Based Localization

This paper describes, validate and evaluates in real environments a very simple self localization methodology for RF-based devices based only on RF-connectivity constraints to a set of beacons (known nodes), applicable outdoors.
