Abstract
Mysterious Location-based Efficient Routing Protocol (MLRT) is an anonymous routing protocol its play a vital role in Mobile Ad
hoc Networks (MANETs). MLRT provide a secure communication by hiding the node identities and preventing the traffic analysis
attacks from outside observers in order to provide a mysterious protection. It dynamically partition the network into subzones till
the sender and receiver are in different zones and the nodes in the zones are connected as intermediate relay nodes. It uses
random relay node selection is difficult for intruder detection and dynamically generating an unpredictable routing path for a
message. It maintains a time limit for message transmission due to security and control the time delay. MLRT offers mysterious
protection to sources, destinations and routes. It achieves better route anonymity protection and lower cost compared to other
anonymous routing protocols. It has a strategy to effectively solve the intersection attacks and avoid timing attacks because of its
non-fixed routing paths for a source and destination pair. Also MLRT mainly works on Greedy Perimeter Stateless Routing
(GPSR) algorithm.

1. INTRODUCTION
Rapid development of MANET can be used in a wide
number of areas such as commerce, emergency services,
military, education, and entertainment. MANET is a self-
configuring network of mobile wireless devices. Devices in
a MANET can move either independently or as groups in
different directions. Therefore, network topology and links
between devices change frequently. Each device may
function as a relay and forward traffic destined for other
devices. MANETs may operate autonomously or may be
connected to other networks.
The existing anonymous routing protocols in MANETs can
be mainly classified into two categories: hop-by-hop
encryption [1] and redundant traffic [2] .Both the two
techniques are generate high cost and cannot provide a
mysterious protection to sources , destinations and routes.
Hop-by-Hop encryption technique is based on public key for
data encryption and decryption. Due to this redundant traffic
technique heavy traffic will be occurred in large data
transmission. Effects of the two techniques are no security,
high cost and heavy traffic. In addition, many approaches
cannot provide anonymity protections. For example
ALARM [3] cannot protect the location anonymity of
source and destination, SDDR [1] cannot provide route
anonymity, and ZAP [4] only focuses on destination
anonymity. To transfer the message from sender to receiver
in a security way and offer a mysterious protection at a low
cost propose a Mysterious Location-Based Efficient Routing
Protocol (MLRT).
Fig -1: System Architecture Design
The scope of the MLRT is that hide the node identities and
routes from outside observers in order to provide the
mysterious protection. It split the network into sub zones till
the sender and the receiver are in different zones and nodes
in the zones are connected as intermediate relay nodes
which form a non-traceable anonymous route. Each node
itself maintains a location server and randomly selects a
node in the zones as temporary destination and transmits the
message to a temporary destination that is closer to the
destination achieved by GPSR algorithm. There is a time
limit in the message transaction. The time limit will exceed
message will expire due to security and control the time
delay. MLRT offers full mysterious protection to sources,
destinations and routes. It achieves better route mysterious

protection and lower cost compared to other anonymous
routing protocols. Also MLRT mainly works on Greedy
Perimeter Stateless Routing (GPSR) [5] algorithm. MLRT
is comparison with other anonymity and geographic
routing protocols. In summary the contribution of this
paper includes:
1. Mysterious routing. MLRT provide a route
anonymity, identity, and location anonymity of
source and destination.
2. Low cost, Instead of hop-by-hop encryption and
redundant traffic, MLRT mainly uses
randomized routing of one message copy to
provide mysterious protection.
3. Resilience to intersection attacks and timing
attacks. MLRT has a strategy to effectively
solv e counter inter-section attacks. M L RT can
also avoid timing attacks because of its non-fixed
routing paths for a source-destination pair.
2. METHODOLOGY
2.1 MLRT Routing Algorithm
All the nodes register in the database with particular IP
address and registered successfully. The node registration is
for to identify all the correct users in the database, and for
the communication between the sender and the receiver, and
also give the security to data and protect to the data
transmission between the sender and the receiver. Node
registration is using the node name, internet protocol
address, port number and the node range for the security
purpose. Above process is for unique identify and the
malicious node should not attack the data in the source node.
The registered nodes are shall with a range of 1 to 500
because in that range it divide the whole network into zones.
And when the user enters the range according to the range
the zone folder is created and inside the zone folder the
nodes have been placed for the routing. Due to the process it
can provide full security to the message and the message
transmission between the nodes are safe and secure.
The MLRT routing in this paper it checks the sender and
receiver location. If the sender and receiver are in the same
zone means it will divide the zone into subzone due to
protection from the malicious users. If not same means
connected as an intermediate relay nodes. MLRT aim is
sender and receiver should be in the different zone. If the
zone of the sender and the receiver is zone2 means it will
divide the zone into zone2.1 likewise it divide the zone into
subzone.
2.2 Dynamic Pseudo Name
In MLRT pseudo name is generated in each node location
server. The pseudonym is generated randomly in each node.
Each node uses the dynamic pseudo name for node
identification. To prevent an attacker from re-computing
the pseudo name, the timestamp should be exact(e.g.
nanoseconds).Considering the network delay, the
attacker needs to compute, e.g.,105,times for one
packet per node. There may also be many nodes for an
attacker to listen, so the computing overhead is not
acceptable, and the success rate is low. To further
make it more difficult for an attacker to compute the
timestamp, increase the computation complexity by
using randomization for the timestamps. Specifically,
keep the precise of timestamp to a certain extent, say 1
second, and randomize, The digits within 1/10th.
Thus, the pseudonyms cannot be easily reproduced.
Also, every node maintains a routing table that keeps
it’s neighbor’s pseudonyms associated with their
locations. Source node signs to intermediate node by
the port number. If the IP address and the port number of
the sending node are correct means the location server
generate the pseudonym and send the pseudonym to the
particular address of the sender. And the sender again
resends the message with the pseudonym to the intermediate
node and the intermediate node not able to see the data. And
it acts as the random forwarder and sends the data to the
temporary destination. The pseudonym is stored in the
database and when the intermediate node send the
pseudonym to the source node means the sent pseudonym is
deleted in the database. And again that pseudonym will not
be generated. The above process is for security and the
malicious node cannot predict through which pseudonym
the message is transmitted that’s why it randomly generate
the pseudonym that process is to enhance more security to
the project and secure the data from the malicious attackers.
2.3 Location Server
In MLRT location servers play a significant role. Each node
itself handles a location server. When a node moves it will
periodically update its position to location server in the
range of 1to500. Location servers maintain routing
information and generate a dynamic pseudo name. In
location server contains information about random
forwarder and temporary destination zone.
2.4 Random Forwarder
The source node signs in the intermediate node by the port
number and if the port number is correct the intermediate
node sends the pseudonym name to the source node and the
source node again signs in with the message with the
pseudonym and select the random forwarder or the
intermediate node through greedy perimeter stateless routing
algorithm and selects the intermediate node through the
distance and intermediate node acts as the random forwarder
and repeat the same process and selects the temporary
destination through greedy perimeter stateless routing
algorithm and sends the message from the intermediate node
to the temporary destination. In the temporary destination it
selects the random forwarder through the greedy perimeter
algorithm, which give high priority to the node which is
nearer to the destination and the message is transmitted to
that node and give high priority to node the process
continues until the message reach the destination. Random
forwarder node should be hiding from malicious attackers to

achieve a security. The number of random forwarders
determines the length of the routing path in MLRT.
3. SYSTEM IMPLEMENTATION
3.1 Mysterious Protection and Strategies against Attacks
3.1.1 Mysterious Protection
It tells about the mysterious protection from the malicious
users and to protect the message from the attackers. In the
Intersection attack the registered nodes for a node registered
with IP address and its name and the port number that node
is a valid node. The network node can be identified through
the port number. Any unwanted malicious node with the
different node name and the different IP address can be
easily identified and it can prevent the message from the
malicious users. In timing attacks going to set the time to the
message source node set the message time for example say 1
second. It could get reply from its destination stating that
received the message successfully. If the reply has not yet
come after 1 second means it states that any malicious nodes
attacks the message the message will automatically expire
after 1 second to avoid the above type of attacks. If the
malicious node attacks the message with the particular time
means also the message should be drop that states that the
malicious node attacking the message. In the case also the
message should be dropped. It gives full security to the
message.
4. PERFORMANCE AND OUTPUT
The Previous work was long time process. In this work
developed using Java Swing. The Previous work caused
long time transmission process but the system developed
now has a very good user-friendly tool, which has a menu-
based interface, graphical interface for the end user. In
previous work every node separately maintains a location
server. So the cost will be high. In propose every node itself
maintain a location server. So the cost will be reduced.

5. CONCLUSION
MLRT is distinguished by its low cost and mysterious
protection for sources, destinations, and routes. It uses
dynamic zone partitions and random relay node selections to
make it difficult for an intruder to detect the two endpoints
and nodes en route. In addition, MLRT has an efficient
solution to counter intersection attacks and fight against
with timing attacks. It includes implementing a Time to live
(TTL) algorithm for security and control the time delay.
