Internet Protocol (IP) by converting the voice Internet Protocol (IP) by converting the voice to a group of Bits collected in to Byte Array to a group of Bits collected in to Byte Array

Then compress it to transfer it as a Datagram Then compress it to transfer it as a Datagram packet through an Ad hock network. packet through an Ad hock network.

In the receiver side, collect the packet in the In the receiver side, collect the packet in the Byte Array then read it as First In First outByte Array then read it as First In First out

MethodologyMethodology

TTo solve the problem several protocols were o solve the problem several protocols were implemented. This was discovered when a implemented. This was discovered when a literature survey was made.literature survey was made.

MeshDriverMeshDriverMeshDriver provides self-organizing, self-healing networking functionality in an easy-to install software package for end-users and system integrators. MeshDriver utilizes devices that you already have, no new hardware is needed!

ConclusionConclusion

We can manage an ad hoc network between the three nodes drive by the MeshDriver .It is work as a cross between the two nodes. MeshDriver relies on established connectivity between devices. For example, it does not automatically configure wireless adapters and establish wireless connections. using wireless adapters in Ad-Hoc mode is one way to establish wireless connections automatically.
