To ensure the survivability of sub sources.
To reduce the maintainance cost of the network.
To ensure data transfer among all the nodes in a network.
The data packet delivery ratio must be sufficiently high
The data transmission delay must be as less as possible.

Objectives of Research
3
Collection of self configurable mobile node connected through
wireless links
Without aid of any existing network infrastructure or central
access point
Each node participating in the network acts both as host and a
router
Characteristics of MANETs :
dynamic topology
node mobility
large number of degree of freedom
self-organizing capability
What is MANET
Node mobility in an ad hoc network causes frequently change
the network topology.

Broadcast ROUTE REQUEST packet
Nodes check the duplicity of packet; if the packet is
duplicate the discarded otherwise continue the process
ROUTE REPLY packet to
source telling how to get

Increment Hop count, rebroadcast the ROUTE REQUEST
packet to adjacent nodes and store info in its reverse route
table
Check the dest. sequence number

Conclusion
The existing system is working well with main source. But in the absence of that main soure hole system will be damaged.
We proposed a solution in this case of problem, where main source will be absence and sub-source are connected with each other when they want to send data in a network.
Hence nodes are dynamic and infrastructure less ,there is a great challange in this way of solution.
To overcome these challange, a specific node will query a neigbour node in multicast network and send ROUTE REQUEST. Repeating this process data transfer between two node will be done.
