Offline Messenger - For Devices Out of Direct Bluetooth Range

As time progresses, people are being more dependent on the advanced technologies available for communication. Hence there is a need for an application which can be used in an emergency situation where all communication networks fail. The Bluetooth technology is used here. The traditional Bluetooth technology can be used only for a one to one communication between two devices which are in the range of each other, but here it is extended to a communication between more than two devices which are not available in the Bluetooth range. More precisely, the application breaks the limit of the Bluetooth technology and implements the communication. The available intermediate nodes are utilized for rendering the message to the node which is out of the limit of the master node. The security of proper communication is maintained as, even if the message hops through the intermediate nodes to reach its destination, the message will not be visible in any nodes other than the intended receiver. The application called Offline Messenger, which has been developed using the procedures as mentioned in this paper would be a complete breakthrough in the world of communication as it breaks the conventional concept that the devices should maintain any sort of direct connection with each other for a Bluetooth communication to take place.
