Multi-agent information system for the assistance to urban mobility
Hayfa Zgaya, Slim Hammadi · 2014
Abstract:- According to the exponential growth of services available on large distributed networks, transport customers require relevant, interactive and instantaneous information during their travels. Thus, we designed and implemented a multi-agent information system using a special kind of software agents: the Mobile Agents. This work belongs to the national French project VIATIC.MOBILITE from the industrial cluster I-trans * , which is an initiative bringing together major French players in rail technology and innovative transport systems. The proposed system uses a two-level optimization approach based on metaheuristics. However, some network errors can occur during the mobile agents moving through the distant network nodes (bottleneck, failure, crash…). In this paper, we define a mobile agent negotiation process to reassign required services to available network nodes according to their current states in their correspondent final routes called Workplans. Consequently, we designed and implemented a flexible transport ontology which allows an easy handling of the terms and messages for negotiating. Key-Words:- Multi-agent system, Mobile agents, Negotiation protocol, Ontology. 1
