Abstract: A mobile ad-hoc network (MANET) is autonomous, self organizing and self-configuring network with the capability of rapid deployment in response to application needs. In our simulation we use DSR (dynamic source routing) that provide MANET route request flood and maintenance of routing but one is the measure challenge is energy issue in mobile ad-hoc network, because mobile node are energy constraint devices, In this paper we proposed LEACH and DSR routing and find-out reliable path (higher energy base route selection), in our proposal LEACH generate cluster and gives information about energy of each cluster belongs zone and if energy of an of the node is higher so LEACH select that particular node for data transmission that work increases the reliability to the communication, in this paper we also analyze the result in the form of network parameter like throughput, packet delivery ratio, energy consumption via node and routing overhead.
