Data delivery in Delay-Tolerant Networks (DTN) is quite challenging since end-to-end paths may never exist. However, data can be opportunistically forwarded via nodes that had contacts with the destination or that belong to the same group of the destination. In a world where devices are becoming very powerful in terms of processing and storage, it is expected that human-carried devices may become part of DTNs, also known as Pocket-Switched Networks (PSN). In PSNs, forwarding may be done opportunistically based on the mobility behavior of humans. However, the e ciency of PSNs may deeply depend on the accuracy of mobility prediction. The current routing trend is to consider human behavior regarding social relationships where a social-aware approach to opportunistic routing in DTNs may present higher e ciency, since human relationships are less volatile than human mobility. In addition, this latest routing trend is also taking into account interest of users to help forwarding. Another aspect that can also be considered is the existing legacy infrastructure that can have an important role in routing information. Thus, the goal of this PhD Thesis Work Plan is to devise and evaluate novel designs for social-aware opportunistic routing.
