Secure Routing Based on Social Similarity in Opportunistic Networks
—The lack of pre-existing infrastructure or dynamic topology makes it impossible to establish end-to-end connections in Opportunistic Networks (OppNets). Instead, a storeand-forward strategy can be employed. However, such looselyknit routing paths depend heavily on the cooperation among participating nodes. Selfish or malicious behaviors of nodes impact greatly on the network performance. In this paper, we design and validate a dynamic trust management model for secure routing optimization. We propose the concept of incorporating social trust into the routing decision process and design a Trust Routing based on Social Similarity (TRSS) scheme. TRSS is based on the observation that nodes move around and contact each other according to their common interests or social similarities. A node sharing more social features in social history record with the destination is more likely to travel close to the latter in the near future and should be chosen as the next-hop forwarder. Furthermore,...
