This paper proposes an ad-hoc network system based on mobile agents. We regard some special mobile agent as an implementation of the network protocol. Mobile agents can move over the network while being carried by protocol agents. Implementation of the protocols by the mobile agents enables the dynamic extension of the network. We introduce agent replication for the simple development of the in...

The Semantic Web aims at augmenting the WWW with meaning, assisting people and machines in comprehending Web content and better satisfying their requests. Intelligent agents are considered to be greatly favored by Semantic Web technologies, because of the interoperability the latter will achieve. One of the main problems in agent interoperation is the great variety in reasoning formalisms, as a...

Closed frameworks such as DESIRE, strongly based on a platform, provide more complete solutions thanothers such as Jadex or TuCSoN. They usually offer anagent architecture and a system model, very useful fornovel developers, together with...

In this paper we describe a semantic knowledge model of an agent as well as implementation and use of such model using the Jena semantic library and the JADE agent system. The solution has been used and evaluated in the Pellucid and K-Wf Grid projects.

In the operation management environment, the process of production scheduling is responsible for detailing operating activities by indicating a set of methods and tools that are conditioned, among other restrictions, by the tactical decisions that are made in the production planning environment. Although, theoretically, a bi-directional flow of information should exist among both environments o...

This work compares and contrasts two component frameworks: (1) the web-centric Java 2 Enterprise Edition (J2EE) framework and (2) the FIPA-compliant multi-agent system (MAS). FIPA, the Foundation for Intelligent Physical Agents, provides specifications for agents and agent platforms. Both frameworks are component frameworks; servlets and Enterprise Java Beans (EJBs) in the case of J2EE and soft...

The issue of developing scalable, concurrent and distributed programs has generated a renewed interest in message-passing languages and frameworks. CoDE is an actor-based software framework aimed at both simplifying the development of large and distributed complex systems and guarantying an efficient execution of applications. This software framework takes advantage of a concise actor model tha...

In wireless sensor networks, sensor nodes are typically powerconstrained with limited lifetime, and thus it is necessary to know how long the network sustains its networking operations. Heterogeneous WSNs consists of different sensor devices with different capabilities. One of major issue in WSNs is finding the coverage distance and connectivity between sensors and sink. To increase the network...
