The fundamental challenge in opportunistic networking, regardless of the application, is enabling node cooperation to forward a message. While node cooperation is considered as a fundamental property in such networks, ensuring such a property between two devices in mobile opportunistic networks remains largely unexplored. In this paper, the authors investigate the potential impact of the lack of trust on node cooperation. They adopt a real-trace driven approach to study and analyze the trade-off between trust and success delivery rates in opportunistic networks. They explore leveraging social information to establish trustworthy communication for mobile opportunistic networks.
