Cooperative multihop localization with privacy

2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011
We introduce a cooperative algorithm for self and target network localization with privacy. The algorithm differs form other cooperative localization algorithms in which it does not require nodes to disclose their location or even to measure (or share) their mutual distances.

Probabilistic Cooperative Target Localization

IEEE Transactions on Automation Science and Engineering, 2015
This work addresses the problem of localizing a ground target observed by multiple heterogeneous unmanned vehicles. Specifically, the case of a team of unmanned aerial and ground vehicles is analyzed. Effective collaboration between unmanned aerial and ground vehicles can utilize the strengths of both platforms while mediating their individual ...

Cooperative concurrent mapping and localization

Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003
Autonomous vehicles require the ability to build maps of an unknown environment while concurrently using these maps for navigation. Current algorithms for this concurrent mapping and localization (CML) problem have been implemented for single vehicles, but do not account for extra positional information available when multiple vehicles operate ...

Cooperative Localization and Mapping with Robotic Swarms

Journal of Intelligent & Robotic Systems, 2021
The Cooperative Localization (CL) problem considers the case where groups of robots aim to improve their overall localization by sharing position estimates within the team instead of using landmarks in the environment. Despite being a well-studied problem, very few works deal with the increased complexity when a very large number of robots is used, as ...

Local scheduling for distributed cooperation

Proceedings IEEE International Symposium on Network Computing and Applications. NCA 2001, 2002
The emergence of mobile computing paradigms has created new dimensions for the problem of performing a collection of tasks in a distributed setting. Indeed, an intrinsic feature of mobile computing is that the communication topology changes over time, and some devices may not be able to communicate with others for prolonged periods of time.

AOA Cooperative Position Localization

IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
In wireless sensor networks, it is very important to obtain an accurate position of each sensor node. In this paper, we consider the potential of Ultra Wideband (UWB) signals for positioning due to its special characteristics. Accurate angle of arrival (AOA) can be obtained using UWB antenna arrays. We propose a new cooperative positioning method based

Cooperative and heterogeneous indoor localization experiments

2013 IEEE International Conference on Communications Workshops (ICC), 2013
In this paper we present the results of real-life localization experiments performed in an unprecedented cooperative and heterogeneous wireless context. These measurements are based on ZigBee and orthogonal frequency division multiplexing (OFDM) devices, respectively endowed with receivedsignal strength indicator (RSSI) and round trip delay (RTD ...

Cooperative Localization and Mapping

2006 IEEE International Conference on Networking, Sensing and Control, 2006
Practical realization of autonomous multi-vehicle control in feature rich GPS-denied areas requires that agents possess the capability to generate and share maps with details adequate for successful operation in complex environments. In addition, coordination of behaviors among robotic vehicles in a swarm is greatly enhanced by exploitation of ...

Locally lipschitz cooperative games

Journal of Mathematical Economics, 1981
A locally Lipschitz cooperative generalized game is described by its coalition worth function v defined on the set [0, 1]n of generalized (or fuzzy) coalitions of n players. We assume that v is positively homogeneous and locally Lipschitz. We propose the Clarke's generalized gradient ∂v(cN) of v at the coalition cN=(1,…,1) of all players as a set of ...

Performance analysis of multirobot Cooperative localization

IEEE Transactions on Robotics, 2006
This paper studies the accuracy of position estimation for groups of mobile robots performing cooperative localization. We consider the case of teams comprised of possibly heterogeneous robots and provide analytical expressions for the upper bound on their expected positioning uncertainty.
