System support for dynamic layout of distributed applications

Biologically Inspired Approaches to Advanced Information Technology

2006

Abstract. This paper presents a middleware system for multi-agents on a distributed system as a general test-bed for bio-inspired approaches. The middleware is unique to other approaches, including distributed object systems, because it can maintain and migrate a dynamic federation of multiple agents on different computers. It enables each agent to explicitly define its own deployment policy as a relocation between the agent and another agent. This paper describes a prototype implementation of the middleware built on a Java-based mobile agent system and its practical applications that illustrates the utility and effectiveness of the approach in real distributed systems.

“…Its agent groups can consist of agents working together on a common task, but they are not mobile. The FarGo system introduces the notion of a dynamic layout for distributed applications [7] in a decentralized manner. This is similar to our relocation policy in the sense that it allows each agent to have its own policy, but it is aimed at allowing one or more agents to control a single agent, whereas ours aims at allowing one agent to describe its own migration.…”

“…To solve this problem, a few attempts to organize mobile agents have been proposed, e.g., MobileSpaces [11], CLAIM [5], and FarGo [7]. MobileSpaces and CLAIM enable each mobile agent to be organized within a tree structure and to migrate to other mobile agents, which may run on different computers, with its inner agents.…”

“…MobileSpaces and CLAIM enable each mobile agent to be organized within a tree structure and to migrate to other mobile agents, which may run on different computers, with its inner agents. FarGo [7] introduces the notion of a dynamic layout for distributed applications. It explicitly binds more than one mobile agent to a single mobile agent and, when the latter migrates to another location, it relocates the latter agent at the same destination to follow the former agent.…”

Abstract.A mobile agent system for organizing multiple mobile agents is presented. It provides two unique two mechanisms for dynamically organizing mobile agents, which may be running on single or multiple computers. The first enables a mobile agent to contain other mobile agents inside it and migrate to another mobile agent or computer with its inner agents. It provides an approach to composing large-scale mobile software from a collection of mobile agents and using mobile agents as deployable software components. The second enables a mobile agent to be deployed at computers according to the movements of other mobile agents. It can move a federation of agents running on different computers, over a distributed system. It can build and aggregate distributed applications from one or more mobile components that can be dynamically deployed at mobile or stationary computers during the execution of the application. This paper also presents a prototype implementation of the system and its application.

“…The framework enables two components on 7 As the dynamic creation mechanism is beyond the scope of this paper, we have omitted it here. Although the current implementation was not constructed for performance, we evaluated the group migration of three components (Fig.…”

Dynamic deployment of pervasive services

ICPS '05. Proceedings. International Conference on Pervasive Services, 2005.

Abstract-This paper presents a self-organizing approach to developing and managing distributed software in pervasive computing environments. In such environments, people are surrounded by hundreds of mobile or embedded computers each of which may be used to support one or more user applications due to limitations in their individual computational capabilities. We need an approach to coordinating heterogeneous computers that acts as a virtual computer around a mobile and pervasive computing environment and supports various applications beyond the capabilities of single computers. This paper presents a framework for building and aggregating distributed applications from one or more mobile components that can be dynamically deployed at mobile or stationary computers during the execution of the application. Since the approach involves mobile-transparent communications between components and component relocation semantics, it enables a federation of components to adapt its structure and be deployed on multiple computers whose computational resources, such as input and output devices, can satisfy the requirement of the components in a self-organized manner. This paper also describes a prototype implementation of the approach and its application.
