2 Introduction  Recent Advances in Mobile Technology and Mobile Devices Mobile Computing has become an important part of our life. People are using wireless networks for their day-to-day work  The desire to be connected anytime, anywhere, anyhow has led to the development of wireless networks

Statement of the Problem  In this Proposed work, Focus has been put on the strategy to address the security issue A lot of emphasis has been given on the routing mechanism and Security Area has not been addressed adequately in Existing Research 3

Statement of the Problem  The Main Objective of the Proposed Work can be stated as – “ Modeling and Conceptualize a secure routing protocol for MANETs”.  In order to handle the above problem, the following outline is proposed Evaluation and Analysis of existing ad hoc routing protocols Design and development of the proposed routing protocol 4

Statement of the Problem  The New Protocol will be proposed after proper verification and validation through simulations 5

Protocol Classes 6 Ready to go Whole topology Updates changes Reactive On-demand Little maintenance Cell operations Proactive Overhead Costs Bandwidth Battery power Inflexible

Proposed Work  In our study the On-demand (Reactive) Protocols have a lower communication overhead because the roots are built only when required and there are no periodic updates required.  We consider a Routing Protocol, namely, Ad hoc On-Demand Distance Vector (AODV). The AODV is an on-demand routing protocol based on the concept of reactive routing 7

Security Mechanisms 9

 A pseudo DNA (Deoxyribo Nucleic Acid) based cryptographic algorithm is used in order to secure the MANETs.  The pseudo DNA cryptography is a concept inspired from the field of life science and has been extended to the field of MANETs to secure them. 10

Pseudo DNA cryptography 17

Security Mechanisms  In proposed work, one potential key application will be used known as DNA- based molecular cryptography systems. it provides a much more compact storage medium, and An extremely small amount of DNA suffices even for huge one-time pads. 18

Conclusion  Finally,the New Routing Protocol will be validated through various simulation scenarios, 19
