A-Teams: An Agent Architecture for Optimization and Decision Support

Abstract: The effectiveness of an agent architecture is measured by its successful application to real problems. In this paper, we describe an agent architecture, A-Teams, that we have successfully used to develop real-world optimization and decision support applications. In an A-Team, an asynchronous team of agents shares a population of solutions and evolves an optimized set of solutions. Each agent embodies its own algorithm for creating, improving or eliminating a solution. Through sharing of the population of solutions, cooperative behavior between agents emerges and tends to result in better solutions than any one agent could produce. Since agents in an A-Team are autonomous and asynchronous, the architecture is both scalable and robust. In order to make the architecture easier to use and more widely available, we have developed an A-Team class library that provides a foundation for creating A-Team based decision-support systems.

Analysing dynamic change in distributed software architectures

Abstract: The software architecture of a system is the overall structure of the system in terms of its constituent components and their interconnections. Dynamic changes to the instantiated system architecture (to the components and/or interconnections) may take place while it is running. In order that these changes do not violate the integrity of the system, we adopt a general model of dynamic configuration which only permits change to occur when the affected portions of the system are quiescent. This paper investigates the feasibility of performing behaviour analysis on systems which conform to the change model. The analysis approach associates behavioural specifications with the components of a software architecture and analyses the behaviour of systems composed from these components. The changes that can occur are modelled as constraints on the architecture, thereby permitting incremental and even concurrent changes. Analysis is used to check that the architecture satisfies the properties required of it: before, during and after the changes. The paper uses an example to illustrate the approach.

Sensor fusion system architecture

Abstract: A sensor system for generating information useful for determining the environment surrounding a vehicle includes multiple sensing zones, with each zone using sensors operating in different electromagnetic bands. The outputs of the sensors are fused to provide more useful information than that obtainable from either sensor, taken alone.

Mobile cloud computing educational tool for image/video processing algorithms

Abstract: This paper shows the importance and benefit of coupling cloud computing with mobile especially due to power limitations that mobile devices exhibit. Moreover, the work done shows that mobile computing can be applied for educational purposes, where a tool for students termed Mobi4Ed is presented. This educational tool aims at exploiting the concept of cloud computing in the context of image and video processing, where students can assess several algorithms in real-time. Two possible system architectures are detailed, where one uses the cellular channel and the other uses the data channel. Consequently, one of the approaches is adopted and a detailed simulation is done where an Android client device is shown communicating with a server running openCV and using the Haar face-detection algorithm. The work assures the credibility of the adopted system architecture, in terms of deployment, and several future lines of work are proposed.
