N2 - The spacial distribution of nodes in the Opportunistic networks is uneven in the real scenarios. There are some landmarks with high node density distributed in the network area. Based on the uneven distribution character of nodes in the Opportunistic Networks, a landmark aware content searching scheme (LACS) is proposed. The scheme proposed here is composed of two sub-schemes, latent spray scheme in the home landmark and searching message infection scheme between landmarks, both of which control the searching message carrier amount in the landmarks, and then control the latency of content searching. The simulation results show that the content searching scheme proposed in this paper outperforms the other schemes by 10% in hit ratio and by 5% in latency of content searching.
