Instant messaging for mobile device with offline and online mode

A system for instant messaging, the system comprising:

• a memory associated with a first computing device, said memory area storing a plurality of instructions;
• a processor programmed to execute the instructions stored in the memory to:
• receive an input, at the first computing device by a user of the first computing device, for sending a message to a second computing device;
• in response to the received input, automatically scan a list on the first computing device to identify an identifier associated with the second computing device;
• determine after the scanning, at the first computing device, a proximity of the second computing device to the first computing device using the identified identifier;
• and
• send the message to the second computing device based on the identification and the determination.

A computer-readable medium comprising executable instructions to enable instant messaging, the instructions being executable to:

• broadcast periodically name and dynamic interests of a user associated with a computing device to one or more nearby available computing devices without disclosing personal information of the user and without getting connected to internet, wherein the name and dynamic interests are broadcasted based on renaming of MAC address of the computing device;
• receive a notification from one of the one or more nearby available computing devices based on matching of the dynamic interests of the user associated with the computing device with interests of the one of the one or more nearby available computing devices, wherein notification are received when the matching is more than a predefined value;
• send a request, without getting connected to the internet, to establish an offline connection with the one of the one or more available nearby computing devices after receiving the notification from the one of the one or more nearby available computing devices;
• receive an acceptance of the request, without getting connected to the internet, from the one of the one or more nearby available computing devices;
• and
• in response to receiving the acceptance, send one or more messages to the one of the one or more nearby available computing devices using an offline mode.
