Anonymous communication systems have recently increased in popularity in wired networks, but there are no adequate equivalent systems for wireless networks under strong surveillance. In this work we evaluate the performance of delay-tolerant friend-to-friend networking, which can allow anonymous communication in a wireless medium under strong surveillance by relying on trust relationships between the network's users. Since strong anonymity properties incur in performance penalties, a good understanding of performance under various conditions is crucial for the successful deployment of such a system. We simulate a delay-tolerant friend-to-friend network in several scenarios using real-world mobility data, analyze the trade-offs of network-related parameters and offer a preliminary throughput estimation.
