In MANET, the nodes can depart and connect the network; this uneven nature makes support of QoS (Quality of Service) is a complex task. A major issue in heterogeneous networks is energy utilization. In this paper, a heterogeneous network is intended to attain enhanced energy-efficient multipath QoS provisioning. Primarily, the multipath routes are assumed to be discovered and they then find the gateway node along with all the nodes in the network by using the gateway selection procedure. By using a QoS based Energy Efficient Optimal Multipath route discovery and route maintenance in multipath routing protocol, discover the optimal path for data transmission from the source to the destination. In this way, QoS parameters such as bandwidth, throughput, packet delivery ratio and end-to-end delay will be computed and accomplish in the best possible way. Keywords: Heterogeneous MANET, multipath routing, gateway selection, gateway migration and QoS provisioning. 1 INTRODUCTION The Mobile Ad Hoc Networks (MANETs) are highly dynamic in nature and infrastructure free. It is consisted of a group of mobile nodes which are not surrounded by any infrastructure. Because of non-restricted mobility these nodes are liberated to move autonomously in any direction and the straightforward deployment’s uniqueness
