This paper considers a system architecture referred to as the mobile agent-based distributed fusion (MADfusion) system. The system environment consists of a peer-to-peer ad-hoc network in which information may be dynamically distributed and collected via publish/subscribe functionality implemented at each node of the network to facilitate data sharing and decision making in Level 2 fusion. The Level 2 decision making process implemented in the system consists of the enhanced doctrinal template matching (EDTM) algorithm which is shown to be an improvement over the pre-existing doctrinal template matching algorithm. This algorithm is developed to operates on information obtained from lower layer fusion processes in order to identify aggregated groups of entities. The template matching algorithm is shown to be an improvement over a previously existing algorithm. The MADfusion system is proposed to extend the client/server architecture of various publish/subscribe applications to an architecture providing decentralization, re-configurability, mobility, attainability and prevention of single points of failure. The system is implemented in a wireless ad-hoc network (802.11b) and performs the publish/subscribe functionality through the implementation of a mobile agent based framework. The software agents travel deterministically from node-to-node carrying a data payload consisting of information which may be subscribed to by users within the network. Within this system, situation awareness (Level 2 fusion) can be sought by using these multi-domain information sources (GMTI, Video, or SAR) for evaluation at each node with different distributed information fusion algorithms.

In order to fuse data from a distributed sensor system, different fusion architectures can be chosen. In this work, distributed data fusion has been applied to data from a ground sensor network. Measurements have been made using five seismic and five acoustic sensor nodes, each consisting of three sensors, on vehicles of five different types. The data were analyzed off-line to achieve tracking and classification of the vehicles. The tracking was made using standard Kalman filters, and classification was made by a combination of a Bayes' classifier and voting. The information system, which made distributed data fusion possible, was based on a combination of intelligent agents and a distributed look-up table for data storage and retrieval. The results indicate that this system can operate on-line with a high accuracy in both tracking and classification.

Air and ground vehicles exhibit complementary capabilities and characteristics as robotic sensor platforms. Fixed wing aircraft offer broad field of view and rapid coverage of search areas. However, minimum operating airspeed and altitude limits, combined with attitude uncertainty, place a lower limit on their ability to detect and localize ground features. Ground vehicles on the other hand offer high resolution sensing over relatively short ranges with the disadvantaue of slow coverage. This paper presents a decentralized architecture and solution methodology for seamlessly realizing the collaborative potential of air and ground robotic sensor platforms. We provide a framework based on an established approach to the underlying sensor fusion problem. This provides transparent integration of information from heterogeneous sources. An information-theoretic utility measure captures the task objective and robot inter-dependencies. A simple distributed solution mechanism is employed to determine team member sensing trajectories subject to the constraints of individual vehicle and sensor sub-systems. The architecture is applied to a mission involving searching for and localizing an unknown number of targets in an user specified search area. Results for a team of two fixed wing UAVs and two all terrain UGVs equipped with vision sensors are presented.

conference on Multisensor, Multisource Information fusion

The wireless intelligent monitoring and analysis systems is a proof-of-concept directed at discovering solution(s) for providing decentralized intelligent data analysis and control for distributed containers equipped with wireless sensing units. The objective was to embed smart behavior directly within each wireless sensor container, through the incorporation of agent technology into each sensor suite. This approach provides intelligent directed fusion of data based on a social model of teaming behavior. This system demonstrates intelligent sensor behavior that converts raw sensor data into group knowledge to better understand the integrity of the complete container environment. The emergent team behavior is achieved with lightweight software agents that analyze sensor data based on their current behavior mode. When the system starts-up or is reconfigured the agents self-organize into virtual random teams based on the leader/member/lonely paradigm. The team leader collects sensor data from their members and investigates all abnormal situations to determine the legitimacy of high sensor readings. The team leaders flag critical situation and report this knowledge back to the user via a collection of base stations. This research provides insight into the integration issues and concerns associated with integrating multi-disciplinary fields of software agents, artificial life and autonomous sensor behavior into a complete system.

Consistency in models for communication constrained distributed learning

17th Annual conference on Learning Theory (COLT 2004)

Motivated by sensor networks and other distributed settings, several models for distributed learning are presented. The models differ from classical works in statistical pattern recognition by allocating observations of an i.i.d. sampling process amongst members of a network of learning agents. The agents are limited in their ability to communicate to a fusion center;the amount of information available for classification or regression is constrained. For several simple communication models, questions of universal consistency are addressed;i.e., the asymptotics of several agent decision rules and fusion rules are considered in both binary classification and regression frameworks. These models resemble distributed environments and introduce new questions regarding universal consistency. Insofar as these models offer a useful picture of distributed scenarios, this paper considers whether the guarantees provided by Stone's Theorem in centralized environments hold in distributed settings.

distributed Autonomous robotic System (DARS) consists of Central Processing part, Communication part. sensor part, and Etc. It is essential for DARS, which is made of independent agents. Bluetooth [1][2] is developed having the features as low power consumption, standard protocol, small module size and Etc. So it is suitable for DARS. But it has some constraints like network structure, distance of communication, and so on. To overcome these constraints, more dynamic network system is needed for DARS. In this paper, we propose the self-organizable bluetooth network base on the routing-tree that is more adaptable for DARS. This network system is composed of the following four network-organization procedures discovery, organization, maintenance, and re-organization [3]. Also this system can operate in more dynamic environment and organize communication network by itself. By the reasons, this self-organizable bluetooth network is suitable for DARS and other dynamic environment.

distributed estimation has advantages over centralized estimation in reducing communication bandwidth, distributing the processing load and improving system survivability. One important technical issue in designing distributed estimation architectures and algorithms is the proper treatment of dependent information. This paper presents graphical models to represent dependent information in general distributed estimation problems. It reviews the use of information graphs to represent dependence due to communication among processing agents so that common information can be identified to avoid double counting infusion. It introduces Bayesian networks to represent conditional independence of measurements given the system states and recognize the minimal set of random variables that satisfy the conditional independence assumption. distributed fusion algorithms that avoid double-counting and reduce communication can be designed by using both information graphs and Bayesian networks. Examples in tracking and classification illustrate the utility of this approach.

29th Annual IEEE conference on Local Computer Networks

We have demonstrated the use of low-cost sensing devices for intelligent control of typical commercial energy loads: cool rooms for keeping produce fresh and heating, ventilation, and air-conditioning (HVAC) systems for buildings. We provide the sensing devices - Berkeley Motes and X10 sensing and switching equipment - with a presence on the internet to permit sophisticated applications to access their data and control their electrical loads. The ad hoc sensor network is connected to the mobile phone network through a light-weight gateway for long-hall communications. Local control provides failsafe default behaviour in the absence of remote control or when communication is lost. We will use this network to deploy agent-based software to manage distributed energy resources, including local generation plants as well as loads. Our aim is to provide new ways for small-to-medium enterprises, energy retailers, and energy network businesses to obtain commercial benefits in a deregulated energy market.

Creating an adaptive embedded system by applying multi-agent techniques to reconfigurable hardware

FUTURE GENERATION COMPUTER SYSTEMS 2004年第6期20卷 1055-1081页

This paper describes how the multi-agent paradigm that is so prevalent in today's distributed reactive software systems can be extended to operate in a dynamically adaptable embedded system environment. In this model, both reconfigurable hardware and the embedded system software design space can be partitioned into autonomous units of execution that are called agents, where each agent has the capacity to interact with the environment and other agents in an intelligent manner. The incorporation of agents that reside in reconfigurable hardware makes it possible to create an intelligent system that exploits the speed advantages associated with reconfigurable hardware within the framework of a unified system model that spans the entire hardware/software continuum. In addition to dynamic adaptability, this approach has the potential to greatly facilitate the flexibility, efficiency, fault tolerance, scalability, and reliability of embedded systems. This paper highlights agent-based reconfigurable embedded systems, and illustrates how they can be applied to a real-time sensor fusion type application using a conventional hardware description language.

Network-centric warfare (NCW) and the interoperability of joint and coalition forces lie among the future warfighting concepts that have been identified by defence. The purpose behind the introduction of such concepts is to "link sensors, engagement systems and decision-makers into an effective and responsive whole, through shared situation awareness, clear procedures and the information connectivity needed to synchronise the actions of the defence farce to meet the commander's intent [1]." To realise the goal of shared situation awareness for NCW, it has long been acknowledged that decentralised data fusion is a key enabling technology, and to this end it has been investigated in terms of distributed target tracking and identification, and the development of distributed agents and ontologies. However, the aspects of interoperability relating to the fusion of disparate types of uncertain (local) data from joint and coalition data fusion systems for shared situation awareness do not appear to have been reported on in the open literature;fusion of disparate types of uncertain data has only been considered for centralised fusion systems. In this paper, these facets of data fusion are considered in tandem for the automatic target identification problem. In particular, a novel Bayesian technique is described and demonstrated for fusing estimates of target identity generated by local data fusion systems which employ a mix of Bayesian probability and Dempster-Shafer formalisms.
