MANET is mobile ad-hoc network. It is simply a collection of nodes where each node acts as independent router or host. Mobility is the main characteristics of MANET. Therefore routing protocol is required that adapts whenever topology changes. Secure data transmission is the main issue in MANET. The enhancement in the secure data transmission in MANET using both reactive and proactive routing protocols. Expecting the performance enhancement in packet delivery ratio, normalized routing load, end-to-end packet delay, throughput, energy consumption, residual energy of secure data transmission in comparison with existing similar routing protocols for MANET.
