Opportunistic networks, in which nodes take advantage of nodes’ mobility to transmit messages, are one of the most effective technologies for developing wireless networks. However, due to the high delay and low delivery ratio in opportunistic networks, such networks have poor transmission performance. In this paper, we propose a Community-driven Hierarchical Message Transmission Scheme (CHMTS) to improve opportunistic routing. In the scheme, we divide the network into communities. We count the encountering times between communities and assign them as communication weights. In the intra-community transmission, we transmit messages based on Prophet Algorithm; however, in inter-community transmission, we transmit messages based on communication weight. Experiments on the ONE show that CHMTS can raise the delivery ratio, improve the efficiency of forwarding messages, and reduce the delivery delay to some extent.
