The routing protocol plays a vital role in mobile ad-hoc networks (MANETs). So, the designing of effective and secure routing protocol in MANETs is a crucial challenge. In current scenario, the mobile ad-hoc networks (MANETs) shows the dynamic behaviour in communication networks. Due to this, researchers face more problem during implementation of secure and effective routing protocol in networks. In this paper, authors have taken numerous factors to design the effective routing protocol for mobile ad-hoc networks in a unified manner. The main motive of this paper is to make some improvement in on-demand multicast routing protocol i.e. DYMO on the basis of energy and traffic pattern parameters with encryption scheme. In this paper, present an enhanced or modified on demand multicast secure routing protocol mechanism i.e. Enhance secure DYMO routing mechanism which follows the efficient energy and minimum traffic load concept to reach out the destination of the message control packet from the source host with encryption. This improved secure DYMO routing protocol mechanism also reconsider the route or path selection procedure as per the energy available at nodes and traffic at nodes with message encryption process using permutation method. For simulation of this system module used NS2 with VM-Ware workstation. A comparative analysis with other on demand routing protocol such as DYMO self-forwarding node, Improved DYMO based on energy and traffic parameter also presented in this paper.
