Software Agent Constrained Mobility for Network Performance Monitoring

Abstract

During the recent years of research on mobile agents, significant effort has been directed towards the identification of models of agent mobility suitable for network management applications. Also, a lot of research work is currently being carried out trying to provide an assessment of mobile agent frameworks used to build agent-based network management systems. In this paper we clarify three different models of agent mobility, present a mobile agent-based performance monitoring system that exhibits the "constrained mobility" model, and discuss its practical use for dynamically programming network elements. The implementation of this system is presented and compared with static object approaches. Furthermore we provide a performance evaluation of the mobile agent based system as it compares with Java-RMI and CORBA distributed frameworks, in order to assess the advantages, along with the overheads, of agent solutions.

Evaluation of Ad Hoc Routing Protocols in Real Simulation Environments

“…Although the concept of constrained mobility was proposed in several papers [11,12,13], however, it is not applied widely to ad hoc networks till now. In reference [13] the focus was on an inter-vehicle communication system application.…”

Implementação e Simulação de uma Aplicação de Gerenciamento Utilizando Agentes Móveis

“…Baldi et al [2] avaliam o uso de paradigmas de códigos móveis no gerenciamento de redes através de um modelo quantitativo. Bohoris et al [3] apresentam uma comparação de desempenho entre agentes móveis, CORBA e Java-RMI, utilizando um elemento em uma rede ATM. Gavalas et al [4] e Sahai e Morin [5] analisam o desempenho do SNMP e do agente móvel quanto à utilização da banda passante e ao tempo de resposta na busca de variáveis da MIB do SNMP em uma rede local.…”
