Robust mobile communication system over opportunistic communication connected to public network

Social media is essential to many consumer services nowadays. To enhance applicable areas, we propose a novel robust mobile communication system even for the case that public wireless network is not sufficiently available, such as in a big event where a large number of people participate or in a disaster situation. We have developed a novel routing method to overcome the technical problems in terms of name resolution and delivery rate, and we have developed also a prototype of the real communication system of smartphones and demonstrated efficiency in the real use case.
