This paper proposes a strong research interest in a field related to bioinformatics and computational biology in a Multi-Agent System (MAS). We promote the use of evolutionary computation within intelligent Multi-Agent Systems taking particularly the enhancement of the NEUron Routing ALgorithm (NEURAL) in Mobile Ad Hoc Network (MANET). More precisely, we develop an intelligent mobile agent called the NEURAL Agent which significantly improves the performance of NEURAL. Results demonstrated that the NEURAL Agent leads to significant benefits in the average end-to-end delay and the packet delivery ratio of the routing protocol.
