Networked Robots: Flying Robot Navigation using a Sensor Net.

TLDR
In this article, the application of a sensor network to navigate a flying robot is introduced. But the robot itself is an integral part of the localization process which establishes the positions of sensors which are not known a priori.
Abstract
This paper introduces the application of a sensor network to navigate a flying robot. We have developed distributed algorithms and efficient geographic routing techniques to incrementally guide one or more robots to points of interest based on sensor gradient fields, or along paths defined in terms of Cartesian coordinates. The robot itself is an integral part of the localization process which establishes the positions of sensors which are not known a priori. We use this system in a large-scale outdoor experiment with Mote sensors to guide an autonomous helicopter along a path encoded in the network.

Multi-Agent Reinforcement Learning: A Selective Overview of Theories and Algorithms

TL;DR: This chapter reviews the theoretical results of MARL algorithms mainly within two representative frameworks, Markov/stochastic games and extensive-form games, in accordance with the types of tasks they address, i.e., fully cooperative, fully competitive, and a mix of the two.

Environmental Wireless Sensor Networks

TL;DR: In this article, the authors present their views as to why this field has progressed less quickly than many envisaged it would over a decade ago, and they use real examples taken from their own work in this field to illustrate the technological difficulties and challenges that are entailed in meeting end-user requirements for information gathering systems.

Mobile-assisted localization in wireless sensor networks

TL;DR: MAL, a mobile-assisted localization method which employs a mobile user to assist in measuring distances between node pairs until these distance constraints form a "globally rigid'* structure that guarantees a unique localization, is described.

Path Planning of Mobile Landmarks for Localization inWireless Sensor Networks

TL;DR: The localization error of three different trajectories for the mobile landmark is studied and the tradeoffs between the trajectory resolution and the localization accuracy in the presence of 2-hop localization, in which sensors that have already obtained an estimate of their positions help to localize other sensors.
