#### K1: Social-Aware Routing in Delay Tolerant Networks

(Keynote Speech)
Prof. Jie Wu, Temple University

Most routing protocols for delay tolerant networks (DTNs) resort to the sufficient state information, including trajectory and contact information, to ensure routing efficiency. However, state information tends to be dynamic and hard to obtain without a global and/or long-term collection process. In this paper, we use the internal social features of each node in the social contact network, a special type of DTN, to perform the routing process. Unlike the traditional fine-grain social-aware approaches that resort to notions of community, centrality, betweenness, and strong and weak ties, our approaches are based on coarse-grain social features. These features are usually known a priori to avoid the complex information collection process in DTNs while ensuring a certain degree of routing efficiency. Two approaches are considered: social feature-based that uses structured contacts among users based on their feature differences, and community home-based that leverages common community home for efficient message spreading. Some insights are also given for efficient information dissemination using social features in a broader context.
