Abstract
The main goal is to find multiple node-disjoint paths that meet the multi-objective optimization problem in terms of energy consumption minimization and network lifetime improvement. Due to the battery-dependent nodes in mobile ad hoc networks, the performance of the network will degrade. Hence, it is necessary to choose multiple optimal node-disjoint paths between source and destination for data transfer. Additionally, it improves the Quality of Service (QoS) of wireless networks. Multi-objective function is used to select a path such that it gives an optimum result based on the energy consumption, hop, and traffic load. From the simulation results, it is proved that the proposed system is achieving less energy consumption and improved network lifetime compared with existing Dynamic Source Routing (DSR), Hopfield Neural Network-based Disjoint Path set Selection (HNNDPS) and Multipath DSR (MDSR).

Mobile Ad hoc Network (MANET) is emerging as the most promising application in disaster and emergency communication management
Function-based Node-disjoint Multipath Routing protocol based on Dynamic Source Routing (DSR), which aims to find multiple node-disjoint paths that meet the multi-objective optimization problem in terms of energy consumption minimization and network lifetime improvement
Previous analysis disclosed that the node-disjoint multipath routing may not be energy-efficient, as there may be a greater number of hops and energy consumption
Summary
Mobile Ad hoc Network (MANET) is emerging as the most promising application in disaster and emergency communication management. MANET protocols have been proposed for achieving energy efficiency by load balancing and routing the network traffic [6,7,8,9,10]. Multipath routing protocols have multiple routes, and this can reduce data transmission delays caused by link failure and distributes high traffic load into multiple paths. The destination node after collecting all the RREQs applies neural network algorithm to the link and node-disjoint path set to select reliable path set. The reliable path set selection is based on the energy function alone It does not concentrate on the hop, and traffic load. It is necessary to optimize the discovered node-disjoint paths based on the multi-objective optimization criteria for providing energy-efficient communication resulting in the network lifetime enhancement. It can be interpreted that the network partitions occur rarely, and the system can reliably transfer packet through the path
