“…As a proof of concept, we used an open source implementation of the Lightweight Directory Access Protocol (LDAP) 6 as the access mechanism to the metadata The messages sent to MagCat agents by other agents are received by means of a cyclic behavior that launches onshot behaviors in order to serve task requests. A behavior is actually a non-preemptive procedure that implements a task or an agent's intentions.…”

“…This can be explored for the development of authorization and authentication mechanisms; (4) Benevolence and adaptability: agents can have goals clearly defined and cooperate in order to achieve their goals and can also change behavior in response to environmental changes; (5) Mobility: agents can migrate from an environment to another, which can be used to develop load balancing mechanisms. Mobility can also be used to move computations instead of data transfers; (6) Ontology: agents use a common vocabulary in respect to the application domain. The ontology allows the identification of environment resources (data, hardware and software devices) and the actions that can be performed on them.…”

Facing the increasing demand for data sharing in distributed environments, computer grids became an attractive technology to manage extended data sets, providing efficient access, publishing, and data discovery. In this paper we present the structure and implementation of MagCat multi-agent system, that provides a service for publishing and discovery data in grids through metadata. This service is being developed in context of MAG, a grid middleware that explores the mobile agent paradigm as a way to overcome the design and implementation challenges of constructing a grid middleware.

Abstract-Mobile cloud computing allows mobile applications to use the enormous resources in the clouds. In order to seamlessly utilize the resources, it is common to migrate computation among mobile nodes and cloud nodes. Therefore, a highly portable and transparent migration approach is needed. In terms of portability, application-level migration with code instrumentation is the most portable approach. However, in the existing literature, this approach imposes significant runtime overhead, even when no migration takes place. Most of these works are for mobile agents, and migrations are to be invoked by the programs. Migration points are also restricted to certain locations where migration status is being polled. In this paper, we propose a Java bytecode transformation technique for realizing task migration without imposing significant overhead on normal execution. Asynchronous migration technique is used to allow migrations to take place virtually anywhere in the user codes, and the proposed Twin Method Hierarchy minimizes the overhead resulting from state-restoration codes in normal execution. We have implemented our approach in our middleware. The results show that our approach can allow lightweight computation migration at application level, achieve considerable speedups and utilize the cloud resources from mobile devices.

SUMMARYThe mobile agent paradigm has emerged as a promising alternative to overcome the construction challenges of opportunistic grid environments. This model can be used to implement mechanisms that enable application execution progress even in the presence of failures such as the mechanisms provided by the MAG middleware (Mobile Agents for Grids). MAG includes retrying, replication, and checkpointing as fault tolerance techniques; they operate independently from each other and they are not capable of detecting changes on resource availability. In this paper, we describe a MAG extension that is capable of migrating agents when nodes fail, which optimizes application progress by keeping only the most advanced checkpoint, and also migrates slow replicas. The proposed approach was evaluated via simulations and experiments, which showed significant improvements.
