An Experimental Approach for Optimising Mobile Agent Migrations

2007

Mobile agents are considered a very interesting technology to develop applications for mobile, pervasive, and distributed computing. Thus, they present a combination of unique features, such as their autonomy and capability to move to remote computers to process data there and save remote communications.

Mobile agents (MA) are autonomous and proactive software entities which act on behalf on an owner and have the ability to migrate through a heterogeneous network of computer. In mobile agent migration, migration strategy is responsible for movement of agent from one host to another, an efficient migration strategy provide the low computation power, low bandwidth utilization. Currently there are several agent platforms which provide different approach of migration. In this paper we compare push and pull oriented approach of migration and analysis the performance with cache mechanism on aglet mobile agent platform.

The paper presents the results of a performance analysis of mobile agents in a distributed network environment. Analytical models are developed and used to compare the performance of carrying out a simple management function with Mobile Agents (MA) or SNMP (Simple Network Management Protocol). We examine how delay is affected by the size of the management domain and how each method behaves in both a local area network (LAN) and wide area network (WAN) environment. For large domains, optimal performance is obtained if the mobile agents size is bounded, and this may require sharing the management task among a small number of mobile agents. * This paper is a postprint of a paper submitted to and accepted for publication in the IET Communication and is subject to Institution of Engineering and Technology

Mobile agents programming paradigm is an emerging approach for distributed computing,extremely suitable for mobile systems because of its adaptability to exploit the available resources. Optimization of mobile agents applications and system configuration are relevant above all when we deal handheld devices with limited capabilities. Classical approaches are hard to apply because new kinds of interaction facilities provided by agent platforms, such as cloning and migration , represent an additional software layer that affects the system performances. In this context identification and estimation of performance indexes are necessary to evaluate and foresee system dependability. In fact performance evaluation is exploited to address different issues according to which, different measurements are required. In practice, there is a need for tools and techniques for evaluation of the performances of the adopted mobile agent platforms. Related work proposes a set of performance indexes, slightly different one from the other, and measured using different approaches. We present here a framework that aims at supporting the development of ad-hoc solutions based on measurement agents. Framework architecture, prototype implementation and case studies and preliminary performance figures are presented in the following.

Conventional network management is based on SNMP and often run in a centralized manna Although the centralized management approach gives network administrators a flexibility of managing the whole network from a single place, it is prone to information bottleneck and excessive processing load at the manager and heavy usage of network bandwidth. The use of Mobile Agent technology fo distribute and delegate management tasks promises to overcome the scalability and flexibility limitations o/the centralized Network Management paradigm. This paper presents distributed management architectures, using mobile agents (MA). Mechanisms building optimal agents itinerary are needed to minimize the total migration cost in terms of the round-trip latency and the incurred traffic. This is of particular importance when the management of networks spanning multiple network domains is involved. On this direction, we have designed and implemented an algorithm which adapts methods usually applied for solving network design problems in the specific problematic of MA itinerary planning. The algorithm not only suggests the optimal number of MAs that minimize the overall cost but also constructs optimal itineraries for each of them. The algorithm implementation has been integrated into distributed network model and tested into real network environments, demonstrating significant management cost savings.

This paper proposes a new framework for mobile agents which would decrease network load in cyber net while dealing with a deadlock situation due to the heterogeneous environment. Some of the security issues and their solutions are also discussed to perform a secure and successful migration.

The paper deals with performance evaluation of a mobile agent network that includes a multi-agent system and a set of processing nodes connected by a communication network where it resides and operates. A mobile agent network is described as a queuing system where an agent represents an information unit to be served. Agent hosting, execution and migration are defined as

Mobile agent technology has grown in acceptance over the years for distributed applications, but it is yet to be adopted as ubiquitous solution technique. This is due to its complexity and lack of interoperability. Mobile agent executes on mobile agent platform, these platforms from different vendors are design, and language specific, and are thus non interoperable. In other words mobile agent built on one platform cannot interact with or execute on any other platform. There is a need to provide a common base on which agents from different vendors can interact and interoperate. This work presents a framework for mobile agent interoperability by providing an Embedded Mobile Agent (EMA) system into the Windows Operating System kernel so that it can run as a service; this was done to eliminate the overheads associated with the agent platforms and enhance mobile agents’ interoperability. The targeted OS were Windows XP, Windows Vista and Windows7. https://sites.google.com/site/ijcsis/

In the past few years there has been an enthusiastic interest in mobile agent technology and several platforms have been developed. Some of them have only been used for research purposes while others have been deployed as commercial products. The community is now looking for applications where these platforms can be effectively used. Some comparisons about the functionality of some mobile agent systems have been presented in the literature. However, to the best of our knowledge, there has been no reported study that compares the real performance of the platforms.

Very large networks with thousands of applications and millions of users pose serious problems to the current traditional technology. Moreover, if synchronised client behaviour exists then the limitations are strongly felt. Mobile agent systems can be a suitable technology to answer to these requirements if some aspects of the architecture are carefully designed. This paper proposes a cooperative mobile agent system with a very dynamic and scalable trading service. The system allows applications to deploy servers onto the network to respond to demand making them self-configurable. Clients can also use mobile agents with performance gains. Sets of simulations were performed to study the scalability of the overall system.
