POPULATION DYNAMICS FOR MOBILE AGENT BASED SYSTEMS
Computing systems are increasingly distributed in nature and information is no longer confined to a single computer, but stored on various computers and can be under constant change. As a result traditional computing paradigms, such as the client-server communication model used for Web …

Using Digital Pheromone to Improve the Hitting Time Performance of Mobile Agent-Based Systems
A flexible and lightweight approach is needed to address security concerns on large networks with little computational resources to spare. A digital ant framework is one possible solution, modeled on the movement and interactions among ants of an ant colony using pheromone. However, the movement …

A requirements elicitation framework for agent-oriented software engineering.
… for the early part of gathering requirements for agent-based systems." This thesis examines the difficulties of gathering and expressing requirements for agent based systems, and describes the development of a requirements elicitation framework. Conceptual modelling in the form of Conceptual …

A Comparison of Agent-Oriented Software Engineering Frameworks and Methodologies
Agent-oriented software engineering (AOSE) covers issues on developing systems with software agents. There are many techniques, mostly agent-oriented and object-oriented, ready to be chosen as building blocks to create agent-based systems. There have been several AOSE methodologies proposed …

An exceptional handling service for the contract net protocol family
Autonomous agents are systems that inhabit complex and dynamic environments. Attaining robust behavior in such complex conditions is a key challenge for agent-based systems. This challenge is intensified in multi-agent settings, where a diverse set of agents communicate and coordinate with each …

Fault-tolerant wireless sensor networks using evolutionary games
… an approach to creating robust communication systems in wireless sensor networks, inspired by biological and ecological systems, particularly by evolutionary game theory. In this approach, a virtual community of agents live inside the network nodes and carry out network functions. The agents …

From the ground up : an agent-based model of regional structural change
… dynamics of the farm sector. By utilizing agent-based methods, competition that exists between farm households in land markets is modelled in a dynamic framework. By modeling land markets in this manner, structural adjustments that occur due to the re-allocation of land among farm household …

Agent-based modeling framework for adaptive cyber defence of the Internet of Things
… presents an environment strongly conducive to agent-based systems, which offer a model for autonomous, cooperative, goal-oriented behaviours which can be applied to perform adaptive cyber defence activities. This thesis aims to bridge the gap between theoretical multi-agent systems research and …

Toward a unified view of complex multiscale stochastic systems: A generalized theory of interactions and its computational infrastructure for their universal and efficient investigation
The Internet, societies and the brain exemplify systems whose compositional structure contains numerous interacting parts and coupled scales of irreversible action, driven to a large extent by intrinsic random perturbations that cannot be removed without losing critical information for their …
