Mobile Ad-hoc Network (MANET) consists of wireless mobile nodes that dynamically form a temporary network without depending on any fixed infrastructure. MANET’s are distributed and the routing functionalities are carried out by mobile nodes. Energy consumption is considered as one of the major challenge as the mobile nodes do not possess permanent power supply and they rely on batteries. The paper highlights the protocols in MANET which acts as solution to the energy consumption problems. In this paper the reactive MANET protocols; Ad-hoc ondemand Distance Vector (AODV), Ad-hoc on-demand Multipath Distance Vector (AOMDV) and improved AOMDV named as Ad-hoc On-demand Distance Vector with Fitness Function (FF-AOMDV) are proposed. Fitness function is an optimization technique used for optimal route selection for data transmission. The protocols are implemented using Network Simulator (NS2). Secured data transmission is established with RSA algorithm. The performance of AODV and AOMDV routing protocols are compared with different performance metrics. The FF-AOMDV is compared with existing system. The performance metrics considered for comparison are packet delivery ratio, end to end delay, energy consumption, throughput and routing overheads. The results show that AOMDV protocol outperforms AODV and improved AOMDV performs better than existing system under majority of network parameters.
