Effective information transmission based on socialization nodes in opportunistic networks.

In social communication, mobile devices can be regarded as socialization nodes in social networks. Furthermore, they carry and store useful information. Mobile devices can select destination nodes and deliver messages through opportunistic networks because messages can be securely and conveniently stored, carried, and transmitted with nodes. In this study, a forwarding model in opportunistic networks is built based on socialization nodes. In accordance with a defined stop time, nodes forward messages with the maximum probability when th. The proposed scheme exhibits better performance compared with classical algorithms in opportunistic networks.
