What Is a MANET?

A Mobile Ad-hoc Network (MANET) consists of wireless mobilehosts forming a temporary network without the aid of anyestablished infrastructure or centralized network administration .


3/20

Understanding the working and transfer data packet between two nodes is

very difficult. To understand easily a software simulation is necessary. So this is an

effort to make a simulation of the MANET Routing Algorithm for A Mobile Ad-hoc

Network.


4/20

To build a software that will simulate the MANET Routing Algorithm to transfer data

packets between the mobile hosts in A Mobile Ad-hoc Network by using extended Zone

Routing Protocol[XZRP].The extended features of this project is multicasting and

security.


5/20

The first implementation of wireless ad-hoc networks with mobile nodes was PRNETby DARPA lacks in the areas of network scalability, security, processing capability,and energy management.

Later Survivable Radio Networks (SURANs) were deployed by DARPA in 1983 toaddress the above issues but it was for non-military applications.

Existing wireless infrastructure is expensive and inconvenient to use.

Simple wireless networks require the existence of access points or static base

stations, which are responsible for routing messages to and from mobile nodes withinthe specified transmission area.

` Self-organizing and self healing .Do not require pre-existing architecture.

` Used in military , security -sensitive operations and also for commercialapplications.

` Efficiently updates the topological changes with minimal overhead

` Routing techniques appropriate for mobile environment

` supports network and resource management, addressing, security, and qualityof service.

` MANET comprises a special subset of wireless networks since they do notrequire the existence of a centralized message-passing device.


7/20

In this simulation of Mobile Ad-hoc Networks four modules arepresented. They are:

` Simulator

` Zone divider

` Controller

` Message Communicator

` The underlying purpose of simulation is to shed light on theunderlying mechanisms that control the behavior of a system.

` In this project mainly we use the AWT concepts. It is an AP I that provides a set of classes and interfaces to create GU I programs. It is implemented in java.awt.package.

` It divides the whole area into number of Zones. In this project zonesare dividing in the hexagon shape.

` Hexagon has the maximum area given the maximum distancebetween two points in adjacent zones is fixed .


10/20

` The Controller can controls the Zone divider and also the messagecommunicator.

` The Zone discover for the protocol is simple, elegant andcomprehensive.

` Any node can perform Zone discovery on any other node at any pointof time. Since we have a static zonal topology, all the source needs isthe current Zone ID of destination.

` Given the start zone and target zone and the hexagonal mesh,finding shortest route(s) is trivial


11/20

The duty of the Message Communicator is to communicate the

messages from source to destination by using the messagenetwork.

In this Message communicator four points are important:

` Request

` Response

` Sending of data

` Acknowledgment

Ad hoc networks can be implemented using various techniques like B luetooth or

WLAN for example. Ad Hoc networks need very specialized security methods. There is no

approach fitting all networks, because the nodes can be any devices. The computer security

in the nodes depends on the type of node, and no assumptions on security can be However,

it can be used with relatively small networks and potentially some very nice applications

can be realized. Although some peer-to-peer type of solutions work nicely already today, it

would be nice to see that some new and innovative solutions would be seen in the arena of

ad hoc networks since it is not hard for one to imagine a countless number of nice ad hoc

based applications that would make the world at least a bit better place.
