We present a game-theoretic approach to Level 2/3/4 fusion for the purpose of Space Situational Awareness (SSA) along with prototypical SW implementation of this approach to demonstrate its effectiveness for possible future space operations. Our approach is based upon innovative techniques that we are developing to solve dynamic games and N-person cooperative/non-cooperative games, as well as a new emerging homological sensing algorithms which we apply to control disparate network of space sensors in order to gain better SSA.
Recent advancement in sensor networks provides a platform for applications that requires in-network data fusion and parallel algorithms. However, processing data in parallel while propagating at low latency is very ch...

Reaching consensus on a self-organized wireless sensor networks through totally decentralized algorithms is a topic that has attracted considerable attention. The average consensus method is the most popular algorithm used in this kind of applications. The main advantage of these approaches is that the network does not involve a fusion center to organize nodes. Using a realistic environment to check the behavior of this scheme is the major objective of this work. Moreover, this paper contributes to answer and confirm some results which are approved by theoretical works.

A new trend in modern Assistive Technologies implies making extensive use of ICT to develop efficient and reliable "Ambient Intelligence" applications dedicated to disabled, elderly or frail people. In this paper we describe two fall detectors, based on bio-inspired algorithms. Such devices can either operate independently or be part of a modular and easily extensible architecture, able to manage different areas of an intelligent environment. In this case, effective data fusion can be achieved, thanks to the complementary nature of the sensors on which the detectors are based. One device is based on vision and can be implemented on a standard FPGA programmable logic. It relies on a simplified version of the Particle Swarm Optimization algorithm. The other device under consideration is a wearable accelerometer-based fall detector, which relies on a recent soft-computing paradigm called Hierarchical Temporal Memories (HTMs).
In this paper, we describe a method and system for robust and efficient goal-oriented active control of a machine (e.g., robot) based on processing, hierarchical spatial understanding, representation and memory of mul...

Roll angle and height of the center of gravity are important variables that play a critical role in the calculation of real-time rollover index for a vehicle. The rollover index predicts the real-time propensity for rollover and is used in activation of rollover prevention systems such as differential braking based stability control systems. sensors to measure roll angle are expensive. sensors to estimate the e.g. height of a vehicle do not exist. While the height of the center-of-gravity does not change in real-time, it does change with the number of passengers and loading of the vehicle. This paper focuses on algorithms to estimate roll angle and e.g. height. The algorithms investigated include a sensorfusion algorithm that utilizes a low frequency tilt angle sensor and a gyroscope and a dynamic observer that utilizes only a lateral accelerometer and a gyroscope. The performance of the developed algorithms is investigated using simulations and experimental tests. Experimental data confirm that the developed algorithms perform reliably in a number of different maneuvers that include constant steering, ramp steering, double lane change and sine with dwell steering tests.

We present here an exploration of enabling MIMO spatial multiplexing in a long range LOS point-to-multipoint link such as might be found in a ground-to-air sensor network backhaul or LOS cellular configuration. The paper focuses on the capacity between a single multi-antenna sensor and an airborne multi-antenna transceiver, facilitated by an airborne single-antenna repeater. The multi-point aspect is treated by showing the regions on the ground where any multiple-antenna sensor in those regions could receive high capacity service. This repeater-assisted capacity enhancement (RACE) technique yields a capacity improvement of approximately a factor of two relative to the configuration without the repeater. A large geographical area may be serviced by proper design of system parameters. In the sensor network backhaul configuration, this capacity improvement may enable higher fidelity sensorfusion algorithms than currently possible because of link limitations. In the cellular configuration or any multi-user communication system, this technique may enable data-intensive applications that would otherwise be unavailable because of data rate constraints. To aid the reader in understanding the analysis, a separable metric for capacity is developed, which allows us to consider the impact of the TX/RX configurations separately. This metric may be helpful for other analyses where the RACE concept is found to be useful.
