COPELABS is developing, in the context of the H2020 UMOBILE project, a set of applications that does not require Internet access for users to exchange information. Such opportunistic transmission applications rely on social interaction between devices to better propagate (route) information.
Oi! is one of such tools. Under development with the purpose of allowing message exchange without Internet access, Oi! considers the SOCIO framework to better select nodes to propagate the messages to.
