© 2016 IEEE. The pervasiveness of small mobile devices equipped with multiple wireless interfaces enabled novel communication paradigms: opportunistic data transfer between the mobile devices. In this paper, we consider the heterogeneity in forwarding mechanisms as one of the major reasons which affects the performance of forwarding algorithms. Heterogeneity arises in different contexts, for example in device types (i.e., tablets vs. phones vs wearable), operating systems or node objectives. Each node may have its own objectives e.g. security, privacy, trust, battery life, etc. We specifically address the heterogeneity in nodes objectives and propose two different architectures, cooperative and collaborative. In the cooperative mode nodes can only communicate if they share the same forwarding objective such as saving energy or minimizing delays. In the collaborative mode, all nodes can communicate with other nodes after a negotiation phase within which they find objective trade-offs. We then present three different collaborative algorithms and evaluate all proposed algorithms using real mobility traces to find out the message delivery success rate.
