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 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 ...

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 ...

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.

Cooperative localization of a cascading quadrilateral network

11th IEEE International Conference on Control & Automation (ICCA), 2014
In this paper, we introduce a set of sensor networks, called the cascading quadrilateral network, and study how to compute the positions of its nodes in a cooperative way. We investigate the condition for determining whether all the sensor nodes are localizable. If not, we provide a method to detect the un-localizable nodes for the whole network.

Heterogeneous Cooperative Localization for Social Networks

International Journal of Wireless Information Networks, 2013
Location-aware techniques has become a hot research topic with great value in commercial and military applications. Cooperative localization, which utilizes multiple sensors in portable devices to estimate locations of the mobile users in the social networks, is one of the most promising solution for the indoor geo-location.
