Hierarchal Object Oriented Fault Tolerant Secured and Atomic Mobile Agent Model
نویسنده
چکیده
Mobile Agents are soft wares migrating from one node to another to fulfill the task of its owner. Mobility introduces two major challenges in front of mobile agent namely reliability and security. As the agent moves from one node to another the goal to complete its task safely is difficult to achieve. Mobile agents are no longer a theoretical concept, much architecture for their realizations have been proposed. However, it has to be confirmed that any failures (machine or agent) do not lead to blocking of agent together with the security issues. This paper proposes a model which deals with both the problems; Fault Tolerance and Security, further it also adds atomicity to mobile agents execution i.e. either all the goals are achieved or none is achieved. This paper proposes a Hierarchal model which uses the concepts of object oriented technology, grouping, atomicity and authentication to deal with the blocking problem and security issues.

Abstract Using mobile agents, it is possible to bring the code close to the resources, which is not foreseen by the traditional client/server paradigm. Compared to the client/server computing paradigm, the greater flexibility of the mobile agent paradigm comes at additional costs as well as the additional complexity of developing and managing mobile agent-based applications. Such complexity ...
متن کاملFault-Tolerant Mobile Agents in Distributed Objects Systems
A transactional agent is a mobile agent which manipulates objects in one or more than one object server so as to satisfy some constraints. There are some types of constraints depending on applications. ACID is one of the constraints, which shows traditional atomic transactions. There are other constraints like at-least-one constraint where a transaction can commit if at least one object server ...
متن کاملEvaluation of Fault Tolerant Mobile Agents in Distributed Systems
The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this article, we present an evaluation of the per formance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We derive the Fa...

An intrusion detection system has become a standard component of security infrastructure. Mobile agents transportable in network, gather information, evaluate and guide the alarm to network administrator. Advantage of having the mobile agent based approach in IDS that there is no centralized failure, less latency rate of data transmission and it has real time capability to generate the alarm ag...
متن کاملVisual Tracking using Learning Histogram of Oriented Gradients by SVM on Mobile Robot
The intelligence of a mobile robot is highly dependent on its vision. The main objective of an intelligent mobile robot is in its ability to the online image processing, object detection, and especially visual tracking which is a complex task in stochastic environments. Tracking algorithms suffer from sequence challenges such as illumination variation, occlusion, and background clutter, so an a...
