We describe the use of the mobile agent paradigm to design an improved infrastructure for data integration in distributed sensor network (DSN). We use the acronym MADSN to denote the proposed mobileagent -based DSN. Instead of moving data to processing elements for data integration, as is typical of a client/server paradigm, MADSN moves the processing code to the data locations. This saves network bandwidth and provides an effective means for overcoming network latency, since large data transfers are avoided. Our major contributions are the use of mobile agent in DSN for distributed data integration and the evaluation of performance between DSN and MADSN approaches. We develop an enhanced multiresolution integration (MRI) algorithm where multiresolution analysis is applied at local node before accumulating the overlap function by mobile agent. Compared to the MRI implementation in DSN, the enhanced integration algorithm saves up to 90% of the data transfer time. We develop objective functions to evaluation the performance between DSN and MADSN approaches. For a given set of network parameters, we analyze the conditions under which MADSN performs better than DSN and determine the condition under which MADSN reaches its optimum performance level.

A hand-designed internal representation of the world cannot deal with unknown or uncontrolled environments. Motivated by human cognitive and behavioral development, this paper presents a theory, an architecture, and some experimental results for developmental robotics. By a developmental robot, we mean that the robot generates its “brain ” (or “central nervous system, ” including the information processor and controller) through online, real-time interactions with its environment (including humans). A new Self-Aware Self-Effecting (SASE) agent concept is proposed, based on our SAIL and Dav developmental robots. The manual and autonomous development paradigms are formulated along with a theory of representation suited for autonomous development. Unlike traditional robot learning, the tasks that a developmental robot ends up learning are unknown during the programming time so that the task-specific representation must be generated and updated through real-time “living ” experiences. Experimental results with SAIL and Dav developmental robots are presented, including visual attention selection, autonomous navigation, developmental speech learning, range-based obstacle avoidance, and scaffolding through transfer and chaining.

To develop lifelong learning skills, we argue that students need to learn how to learn via inquiry and understand the sociocognitive and metacognitive processes that are involved. We illustrate how software could play a central role in enabling students to develop such expertise. Our hypothesis is that sociocognitive systems, such as those needed for collaborative inquiry and reflective learning, can best be understood as a community of interacting agents, who each have expertise in accomplishing particular high-level goals. We introduce a system, named SCI-WISE, that houses a community of software agents, such as a Planner, a Collaborator, and an Assessor. The agents give strategic advice and guide students as they undertake collaborative research projects and as they reflect on and revise their inquiry processes. Students can easily modify SCI-WISE so that it expresses their own theories of how to do inquiry and how best to coach and scaffold the process. We describe curricular activities in which middle school students use SCI-WISE to engage in “inquiry about inquiry, ” thereby making inquiry and metacognition topics of investigation. Finally, we discuss how such activities should lead to improvements in their inquiry learning skills as well as to their metacognitive development in general.

This chapter addresses embodied social interaction inlif6 like agents. Embodiment is discussedf rom both arti cial intelligence and psychology viewpoints. Di#erent degreesof embodiment in biological, virtual and robotic agents are discussed, given the example of a bottomup, behavior-oriented, dynamic control of virtual robots. A `dancing with strangers' experiment shows how the same principles can be applied to physical robot-human interaction. We then discuss the issue of sociality which di#ers in di#erent academic communities with respect to which roles are attributed to genes, memes, and the individual embodied agent.

For a long time, the role of the environment has been underestimated in multiagent systems research. Originating from research on behavior-based agents and situated multiagent systems, the importance of the environment is now gradually being accepted in the multiagent system community in general. In this paper, we elaborate on the role of environments in multiagent systems. We present a model for multiagent systems that puts forward agents and the environment as first-order abstractions. Starting from this model, we elaborate on the logical functionalities of the environment. Competence in engineering environments is a prerequisite to apply environments in practical multiagent system applications. We briefly discuss how current agent-oriented methodologies deal with the environment, and we discuss an approach for engineering environments that puts forward artifacts as building blocks for environments. After that we present the concern-based approach for engineering environments developed in our research group. This approach models the environment as a set of modules that represent different functional concerns of the environment. We illustrate how we have applied this approach in a real-world multiagent system application. The paper concludes with a number of research challenges that are important for the further exploration of environments for multiagent systems.

Reearch into virtual environments on the one hand and artificial intelligence and artificial life on the other has largely been carried out by two different groups of people with different preoccupations and interests, but some convergence is now apparent between the two fields. Applications in which activity independent of the user takes place --- involving crowds or other agents --- are beginning to be tackled, while synthetic agents, virtual humans and computer pets are all areas in which techniqes from the two fields require strong integration. The two communities have much to learn from each other if wheels are not to be reinvented on both sides. This paper reviews the issues arising from combining artificial intelligence and artificial life techniques with those of virtual environments to produce just such intelligent virtual environments. The discussion is illustrated with examples that include environments providing knowledge to direct or assist the user rather than r...

Agent-Oriented Software Engineering (AOSE) is an emerging paradigm within industry that offers much potential of the management of the increasing levels of complexity inherent within modern software systems. For this paradigm to gain widespread acceptance, it is vital that we develop comprehensive frameworks that support the development and deployment of agent-oriented applications. This thesis contributes to this through the development of a four-tier development framework entitled the Agent Factory System. This framework combines an agent programming language that is founded upon a formal agent theory of commitment; a run-time environment that delivers a set of services that support the deployment of agent-oriented applications written in this programming language; an integrated development environment that delivers a toolkit that supports the development of these applications; and a development methodology that promotes a structure approach to the use of this toolkit. Finally, we evaluate the Agent Factory System from the context of various real-world
