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

Proposed Work

In
our
Protocols
study
have
the
a
On-demand
lower
(Reactive)
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

Security Mechanisms

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.

Security Mechanisms

In
proposed
work,
one
potential
key
application will be used known as DNAbased 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,
