The goal of this paper is to serve as a reference for researchers in robotics and control that are interested in realistic modeling, theoretical analysis and simulation of wireless links. To realize the full potentials of networked robotic systems, an integration of communication issues with motion planning/control is necessary. While considerable progress(More)
The goal of this overview paper is to serve as a reference for researchers that are interested in the realistic modeling of wireless channels for the purpose of analysis and optimization of networked robotic systems. By utilizing the knowledge available in the wireless communication literature, we first summarize a probabilistic framework for the(More)
– In this paper we consider a team of mobile robots that are tasked with building a map of the obstacles, including occluded ones, in a given environment. We propose an integrated framework for mapping with see-through capabilities using laser and wireless channel measurements, which can provide mapping capabilities beyond existing methods in the(More)
– In this paper, we consider a mobile robotic network that is tasked with building a map of the objects/obstacles in an environment. We are interested in the see-through mapping of the obstacles, i.e., a mapping approach that can build the spatial variations of the occluded structures. We consider two cooperative mapping approaches based on making a small(More)
— In this paper we consider the problem of distributed load balancing over a directed graph that is not fully connected. We study the impact of network topology on the stability and balance of distributed computing. We furthermore propose Informed Load Balancing (I-LB), an approach in which the nodes first reach an agreement over the balanced state, through(More)
We solve the equations of motion for a scalar field with domain wall boundary conditions in a Friedmann-Robertson-Walker (FRW) spacetime. We find (in agreement with Basu and Vilenkin) that no domain wall solutions exist in de Sitter spacetime for h ≡ H/m ≥ 1/2, where H is the Hubble parameter and m is the scalar mass. In the general FRW case we develop a(More)
