In recent years there is advancement in the
system performance,technologies in wireless   communications. Wireless networks need  networks in which mobile nodes can communicate
over paths. In MANETs, network survivability is must by which the battery
extent of the nodes get weak. Thus to continue the network period the routing
protocol is needed to raise the energy of the node. Multiple routing protocols
support routes to flood the packets i.e., route appeal is directed by the source
to achieve facts concerning the ways. MANETs can be classified into three generations:
first, second and third generations. In 1970’s the ad hoc network first
generation are called Packet Radio Network (PRNET). In early 1980’s Survivable
Adaptive Radio Network (SURAN)is evolved from PRNET. The function group of
MANETs made the routing code standardized and resolve the agents like PDA’S,
palmtops, notebooks. Few standards like Bluetooth, IEEE 802.11(WLAN’S) are
developed to maintain the MANETs. For several years from 1970’s to 1990’s there
are changes in the generations of MANET i.e., finally some standards are made
to maintain the MANET. Energy efficiency is to be regarded as a factor in
MANET. Mainly the packets are transmitted based on the:

·       
Distance
of the route

·       
Residual
Energy of the node.

                     Thus the route that is
efficient and possible in transmitting packets can be identified.Route appeal
is directed by the source to find the route that is capable. All the ways   that are possible   can be find .The facts about the nodes
energy aligned and the connections are sent over the Route Reply. At any time
the channel breaks, the Route Error is send. When this happens the source
transmit the package through the path to the destination without any
interruption. This can be done with the multipath routing protocol which are referred
to the one path routing protocol. In one path routing once the link breaks the
packets cannot be transmitted. Whereas in multiple routing other routes can be
refered to send the data packets. Particle Swarm Optimization (PSO) is the algorithm
from which the fitness function is derivative. Fitness Function is mostly used
to find the optimal path.The optimum route is  the route with:

·       
Less
distance and

·       
Consumes
less energy.

              The optimal path minimizes the
energy loss and maximizes the network lifetime. Thus the proposed FF-AOMDV
performance in maximizing the network lifetime is possible compared to the
AOMDV.

TO WHOMSOEVER IT MAY CONCERN

It is with immense pleasure that I write this letter of
recommendation for the truly outstanding Vaibhav Anand. He had been in this
school since its inception. In my decade counseling students, it is very rare
to encounter a pupil with as much compassion and self-awareness as Vaibhav. His
resilience, optimism, and valor are chiefly striking given the unusual
circumstances he has overcome in his life. Given the depth of his experiences
and his sophisticated perception of life, Vaibhav has an unusual maturity
beyond his eighteen years.

Vaibhav has undergone significant tragedies in his life. At
a very young age (eleven years old) he lost his mother due to meningitis but
still he performed exceptionally well in his studies in subsequent classes and
exhibited a profound interest in computers and technology; he would develop
virtual machines, code programs in C++, invent scientific operational models
and take pleasure in solving mathematics. He was the topper in the grade 11 in
the subject Mathematics. However, during high school leaving / final exams
(twelfth-grade), Vaibhav’s father had committed suicide, which had affected
Vaibhav’s final twelfth-grade exams significantly. I strongly believe that the
grades earned by him in his final twelfth-grade exams do not evince his true
potential. Throughout these unstable and uncertain times, Vaibhav diligently
devoted himself to his education while balancing to manage his distressed home
condition, which compelled him to take a gap year (after graduating from high
school in May 2017) to look after his younger brother. He has taken
responsibility for his younger brother along with managing other essential
household responsibilities simultaneously.

After keeping all that in mind, I believe Vaibhav is an
industrious young man with great fortitude to withstand such life challenging
situations. Based on the incredible resilience and infectious enthusiasm
Vaibhav has shown throughout the setbacks in his life, I have no doubt that he
will not only continue to deal with anything that comes his way but also will
thrive with great strength, grace, and an optimistic outlook.
