Maintaining mobile agent availability in the presence of agent server crashes is a challenging issue since developers normally have no control over remote agent servers. A popular technique is that a mobile agent injects a replica into stable storage upon its arrival at each agent server. However, a server crash leaves the replica unavailable, for an unknown time period, until the agent server ...

Mobile Agent technology is emerging as a new paradigm in the area of distributed and mobile computing. Its paradigm has attracted many attentions but it is still not widely used. The reason for this is that it suffers from the various issues regarding reliable mechanisms like security and the fault tolerance in mobile agent system. Mobile agents have uniqueness that they can migrate from one se...

The paper presents the formal modeling and simulation framework for mobile agent systems . A Mobile Discrete Event System Specification (MDEVS) formalism is proposed to represent the dynamics of mobile agent systems . The MDEVS formalism supports the structural changes of systems that include creation, addition, deletion, and migration of models and the dynamic changes of couplings between mode...

The design, development, deployment and use of mobile agent in computing is a relatively new paradigm in distributed systems environment. The deployment of mobile agent in creating distributed systems has been shown to help reduce network load, overcome network latency and encapsulate protocols as well as help the dynamic adaptation, and asynchronous and autonomous execution of distributed appl...

This paper aims to investigate mobile agent scalability in network management in order to nd when mobile agents can improve the management e ciency Mobile agent performance is compared with the SNMP one in management task simulations Response time results show that the mobile agent is less sensitive to the latency and the bandwidth of a bottleneck link that connects the management station to a ...

Mobile agents can be regarded as software components which can move from host to host to perform computations. Research over the past halfdecade has found the mobile agent paradigm to be useful for many applications. This paper aims to show the broad applicability of mobile agent technology in the enterprise, and to explore the implications of this broad applicability from an architectural pers...

Fault tolerance schemes for mobile agents to survive agent server crash failures are complex since developers normally have no control over remote agent servers. Some solutions modify the agent server platform, e.g. a replica of the mobile agent is injected into stable storage upon its arrival at an agent server. However in the event of an agent server crash the replica remains unavailable unti...

Mobile agents are a class of software agents that have the ability to move from host to host and are particularly relevant for mobile and distributed applications. The development of several mobile agent implementation environments has necessitated conceptual modelling techniques for mobile agent applications. In this paper, we present mGaia, our extension of the Gaia Agent Oriented Software En...

Mobile agents have great potential for increasing the realized benefit for a variety of e-commerce applications. However, enabling the mobile agent to safely travel over the open and uncontrollable Internet is necessary to protect the contents of a mobile agent. Recently, many agent structures that manage the keys needed to provide the access control mechanism for mobile agents have been develo...

with recent developments in communication technologies, it is possible to access information any time and in any place; however, mobile environments bring forward certain requirements and exclusive challenges including low connection speeds and bandwidth limitations. thus, we need to consider mobile limitations when using web services. providing services and limited resource allocation to users...
