Abstract:
Contact-based messaging applications establish a short-range communication directly between mobile devices, storing the messages in the devices in order to achieve a full dissemination of such messages. When a contact occurs, the mobile devices interchange their stored messages, following a epidemic diffusion. No messages are sent or stored in servers. In order to evaluate the diffusion of messages among mobile devices based on opportunistic contacts, we developed GRChat, an Android application that uses Bluetooth as near-by communication protocol. We present some results about the efficiency of peer-to-peer message diffusion depending on message size and devices distance.
