MANET is one kind of self-configuring and dynamic wireless network that has numerous transferable consumer equipments. Mobile nodes communicate with each other without any fixed central base station to monitor the nodes and to transfer data between the nodes. Multi-protocol label switching (MPLS) is a scalable network that is used within the MANET. These networks have many issues like node failure, link failure, finite transmission bandwidth, broadcasting messages and the establishment of the dynamic link. In this paper, the routing over MPLS based MANET is made by the combination of fuzzy logic controller based routing (FLCR) which is optimised by particle swarm optimisation (PSO). By optimising the FLC with PSO, the optimum node is selected for generating the effective transmission path. This proposed method is named as FLCR-MPLS-MANET method. The performance of the FLCR-MPLS-MANET method is analysed in terms of alive nodes, dead nodes, energy consumption, throughput and bandwidth. The performance of FLCR-MPLS-MANET method is compared with the existing method Dist-MANET and BECIT. This Dist-MANET considered only the distance while generating the transmission path in the network. The bandwidth of the FLCR-MPLS-MANET method increased at 43.13% and 95.23% compared to the Dist-MANET and BECIT respectively.
